American Magic Unveils AC75 Boat 'Patriot' in Landmark Moment for 37th America's Cup Campaign

image1

A landmark day unfolded for NYYC American Magic on Tuesday morning, May 7th, as Boat 3, Patriot, embarked on its inaugural sail.

Team members and their families gathered at their Barcelona team base for a christening ceremony preceding the sail of their new AC75, the foiling monohull set to be tested and raced by New York Yacht Club American Magic this summer in advance of the 37th America's Cup.

Clare G. Harrington, Vice Commodore of the New York Yacht Club, had the honor of christening the team’s AC75 "Patriot."

In her address to an enthusiastic gathering of team members, friends, and family, Vice Commodore Clare Harrington commented, "The New York Yacht Club has never wavered from its core purpose of ensuring international competition at the highest level of skill and performance. That is our tradition. However, the launch of Patriot also signifies innovation, blending two distinct elements: tradition and innovation. And so I bring to American Magic the heartfelt wishes of all 3,400 plus members of the New York Yacht Club for your success in the upcoming competition, maintaining the club's tradition through your inspired innovation."

Terry Hutchinson, President of Sailing Operations at American Magic, contemplated the team's campaign to date, commenting, "As we reflect on the last 21 months, it's remarkable that we set a launch date of just three days from now. As a team, we persevered through adversity, especially in the early stages of the build when things didn't proceed perfectly."

Expressing gratitude towards the team principals, Hutchinson added, "The entire team is immensely grateful to Hap Fauth and Doug DeVos for their unwavering support. Without their vision and backing, none of this would have been possible. As a team, we are dedicated to honoring their commitment by striving for excellence in everything we do."

Acknowledging the collective effort, he continued, "When you observe the families and children present, you realize the immense support, effort, and energy required to bring this boat to the water. While the production team's hard work is behind us, the focus and challenges for the sailing team and designers lie ahead."

In his speech to the team, Mike Cazer, CEO at American Magic, emphasized the team's collective dedication, stating, "Every person on this team understands our mission: to win America's Cup. Moreover, they clearly understand their role in helping the team accomplish this mission, and this team is highly talented and dedicated to the mission."

Cazer also highlighted the team's commitment to fostering a positive culture, saying, "In addition, the team is also committed to creating a positive and strong culture. Our culture reflects the values of our founders, Hap Fauth and Doug DeVos. These values champion excellence, innovation, integrity, unity, and teamwork. They give us a strong foundation to strive to accomplish our mission. To win the cup, to bring it back home to the United States and to the New York Yacht Club.

Building upon the legacy of its predecessors, American Magic’s new boat, Patriot, represents the culmination of US boat design and engineering excellence. Notable advancements include:

  • Enhanced hull design to optimize performance in varying wind and sea states.
  • New lighter foils with an increase in span to 4.5m, facilitating lift out of the water.
  • Upgraded electronics, hydraulics, and software systems for improved control and maneuverability.
  • Reducing crew size from eleven to eight members utilizes innovative cyclors (replacing grinders) powering the yacht's systems.
  • The AC75 features a 26.5-meter mast, meticulously crafted by the American Magic team in the United States.
  • The soft sail design comprises twin mainsails and a headsail (jib), resulting in a total sail area of approximately 230m².
  • This configuration ensures maximum efficiency and performance.

The development of Patriot was a collaborative effort involving American Magic's team of 30 designers, CFD analysts, engineers, naval architects, AI resources, and boatbuilders. Over 108,000 design and 65,000 construction hours were dedicated to refining every aspect of the boat.

Design Coordinator Scott Ferguson reflects, "We followed our own design path with Patriot as we pushed the limits of the AC75 rule while tailoring for the Barcelona venue. Our overall philosophy is minimalistic, as we've tried to squeeze down our volumes to the base minimum while still fitting the crew and systems into the boat. There are tradeoffs for every decision regarding performance, weight, energy, and forgiveness. The design team, together with the sailing, shore, and build teams, have developed what we feel is a strong package for competing at a high level here in Barcelona.”

Patriot is poised to deliver high-performance sailing on the racecourse. The team anticipates that Patriot will excel in speed, agility, and maneuverability, providing a platform capable of winning the 37th America’s Cup.

Details released for 37th America’s Cup

Published on November 16th, 2021 by Editor -->

(November 17, 2021) – The Protocol of the 37th America’s Cup was released today by the Defender, the Royal New Zealand Yacht Squadron and Emirates Team New Zealand and the Challenger of Record – Royal Yacht Squadron Ltd and their representative team INEOS Britannia, eight months to the day after Emirates Team New Zealand successfully defended the America’s Cup.

The Protocol sets the foundations and rules of participation for all teams in the 37th America’s Cup and records the items of mutual consent under the America’s Cup Deed of Gift agreed between the Defender and the Challenger of Record which establishes the basis for a multi challenger event.

Defender Emirates Team New Zealand’s CEO Grant Dalton said: “As we saw with AC36, after 170 years, as the oldest trophy in international sport, the America’s Cup maintains its unique position of balancing the traditions of the Deed of Gift while continuing to push the boundaries of innovation, technology and design in the boats, the event, the broadcast and the commercial aspects of the event.

“Maintaining this balance is the ongoing challenge and responsibility of the Defender and Challenger of Record as we aim to progress into the 37th edition of the America’s Cup in the ever-changing environment and demands of global sports as well as a determination to drive sustainability through innovation via hydrogen technology for the marine sector which we both believe is reflected in this Protocol.”

ac 37 sailboat

INEOS Britannia CEO and Team Principal Sir Ben Ainslie said: “As Challenger of Record, INEOS Britannia has sought with the Defender, Emirates Team New Zealand, to make the next America’s Cup less expensive and more inclusive.

“The Protocol this time around will see reduced team operating costs without compromising any of the technical development which the Cup is so famous for. There is an opportunity for change, so for AC37 we will see the first Women’s America’s Cup Regatta and we also welcome back the Youth America’s Cup.”

An updated ‘Version 2’ of the AC75 Class Rule has been released from the last America’s Cup which specifies the latest requirements to be compliant with the class rule including modification requirements for new teams buying ‘Version 1 AC75s’ that were built and used by teams competing in AC36.

Documents: • Protocol for 37th America’s Cup • AC75 Class Rule Cost reduction has been a key consideration as part of the balance in the development of the AC37 Protocol including:

• Teams are only permitted to build one new AC75. • Limitations on the quantity of foils and componentry that can be built for the AC75s. • Introduction of the multi-purpose One Design AC40 class which teams will be able to convert and use for testing, component development, and Match Race training. • AC40 class will then be converted back to the measured One Design AC40 class for use in the new America’s Cup Women’s Regatta and America’s Cup Youth events. These events have been developed to create new accelerated inclusive pathways into the America’s Cup for the growing global talent pool of female and youth sailors. • Race crew onboard the AC75 reduced from 11 to 8 sailors. • Further one design elements. • Shared team recon. • Supplied starting software. • The AC75 class of boat will be maintained for the next two events.

The shared recon program whilst reducing costs, is also aimed to give America’s Cup fans the inside track on the testing and development on the water by all the teams. The observations will be made public via AC media channels so that fans can stay up to date with the latest developments as they emerge from the sheds throughout the whole of AC37.

With a view to opening the doors and the continued drive to increase the global audience of the America’s Cup and the sport of sailing, a condition of entry to competitors is they agree to be part of a potential behind-the-scenes documentary series. The intention of this is to bring the secrecy, the drama and all the teams’ personalities into the limelight.

There will be up to three Preliminary Regattas, the first two raced in AC40s, the last one at the Match venue in AC75s. The Challenger Selection Series and the America’s Cup Match will be held in 2024, with the Match Venue and approximate event dates to be announced by March 31, 2022.

The Protocol outlines restrictions on when the AC75s can be sailed. With the anticipated benefit angled towards new Challengers to AC37, existing teams are not permitted to sail their AC75s before the 17th of September 2022, however, new Challengers entering AC37 that have purchased a second hand “Version 1 AC75” are permitted to sail their AC75 for 20 days from June 17, 2022. There are other restricted sailing periods which are provisional and will be confirmed once the Match venue is announced.

The Crew Nationality Rule will require 100% of the race crew for each competitor to either be a passport holder of the country of the team’s yacht club as of March 17, 2021 or to have been physically present in that country (or, acting on behalf of such yacht club in Auckland, the venue of the AC36 Events) for 18 months of the previous three years prior to March 17, 2021.

As an exception to this requirement, there will be a discretionary provision allowing a quota of non-nationals on the race crew for competitors from ‘Emerging Nations.’

As part of the ongoing drive for innovation and new clean technology in the America’s Cup, it is now a mandated obligation of all teams to build and operate two hydrogen powered foiling chase boats for their campaign (subject to proof of concept).

It’s hoped showcasing proven hydrogen technology in the marine sector will help create a game-changing pathway for the wider industry and lead to a significant reduction in its carbon footprint. These boats must be a minimum of 10 metres long and the usage and performance criteria is set out in the Protocol.

“A significant proportion of the team’s carbon footprints is in their on-water operations, through their long days of testing, development and training,” said Grant Dalton.

“So for the past year we have been researching, designing, and are now building a prototype hydrogen-powered foiling chase boat which will have a dramatic effect on the reduction of the team’s carbon footprints, as well as pushing the development of hydrogen in the marine sector.”

Race Management will be entirely independent of the event organization and will be led by the Regatta Director. The umpires and jury that will manage all on the water rules and disputes for all events.

• The independent Rules and Measurement Committees will be responsible for interpretation of the AC75 Class Rule and the yacht measurement.

• A three-person Arbitration Panel will oversee and deal with all Protocol disputes with published decisions to maintain the integrity of the event. And there will be a new fast-track process to reduce the potential delays in making decisions on disputed items.

“A lot of work has gone into the AC37 Protocol and we extend our thanks and gratitude to Emirates Team New Zealand and the Challenger of Record – the Royal Yacht Squadron and INEOS Britannia – for their hard work and commitment to an exciting 37th America’s Cup,” said Aaron Young, Commodore of the Royal New Zealand Yacht Squadron.

“Clearly the 36th America’s Cup was hugely successful despite the difficulties and huge restrictions due to dealing with COVID-19 pandemic in New Zealand and globally. But as custodians of the America’s Cup along with Emirates Team New Zealand, it is our responsibility to keep building the event for the good of the America’s Cup, and the sport.

“We especially welcome the inclusion of both the Youth and Women’s America’s Cup as part of the protocol and event, and believe these are important developments that will increase participation and inclusion within the America’s Cup going forward.

“We are also pleased to keep pushing the boundaries of innovation, technology, sustainability, participation, broadcast and the commercial aspects of the event. And so we think we have taken a good step forward in that respect.

“The Royal New Zealand Yacht Squadron will continue to support Team New Zealand as they fulfill their role in the planning, funding and delivery of this AC37 campaign and event.”

Bertie Bicket, Chairman of Royal Yacht Squadron Ltd, regarding the Protocol: “We are delighted with the result of this positive collaboration between the Defender and the Challenger of Record which has resulted in a truly progressive protocol for the 37th America’s Cup designed to promote fair competition and sustainability.

“Furthermore, we believe that the cost reduction measures and introduction of a women’s and youth event provide new and exciting opportunities within our sport.“

Mickey Ickert, Rig and Sails Design Lead, talks AC37 sail design

Bold Protocol is a series published exclusively on www.INEOSBritannia.com to dig deeper into the Protocol that defines the competition for the 37th America’s Cup.    

The Protocol for the 37 th America’s Cup didn’t bring the only rule changes for the latest edition of sport’s oldest international trophy. There was also a new set of class rules for the AC75, and a new set of Technical Regulations. In this sixth episode we are joined by INEOS Britannia’s Mickey Ickert, Rig and Sails Design Lead, to look at how the challenges and the opportunities have shifted in the world of AC aerodynamics .

Mickey Ickert has been designing fast sails since the 1980s, and counts America’s Cup wins with Team New Zealand (in 1995 and 2000) and Team USA Oracle (in 2013) on his CV. He’s also had a lot of success in ocean racing, including designing sails for ABN AMRO 2, winner of the 2005-06 Volvo Ocean Race. So what’s his overview of the new rule environment?  

“I think it was a good clean up from AC36. There’s been a lot of thought gone into it, and some negotiation with Team New Zealand to make sure that the rules are clean and tidy.  I think there’s some progressive stuff there, and they didn't fundamentally change the boats, which is good. I like the fact that some of the loopholes got closed, so that was a good step forward from the AC36 Protocol.”  

ac 37 sailboat

In AC36 an American Magic sail design known as the ‘batwing’ pushed hard at the rules envelope to ‘scallop’ area out of the mainsail between the battens. “The mainsail is now smaller than it was before [as defined by the rule], to take into account that the bat wing’s reduction in sail area was a good thing [for performance].”  

The mast tube itself is unchanged but the running backstay been removed and new rigging supplied to all competitors will improve the overall efficiency of the sailplan even further for AC37. 

The most notable aspect of the AC75’s sails is probably the double-skinned mainsail, one of the major innovations when the boat was introduced and still part of the rule. “I’ve been involved in a lot of different concepts and I was skeptical initially... I think what's important about the double skin concept is that for a boat like this it has some real advantages,” explained Mickey.  

“It's not that it’s fundamentally that much better than a single skin with a rotating mast, but it just makes it that much more efficient, so that the mast height can be reduced. This is important because these boats are very tippy before they take off as the hydrodynamics [foils and wings] don't provide any righting moment [until the boat is moving fast and flying]. So for these boats, it's just enough of a change that it makes the mast short enough that the whole concept works. So I think it's a nice solution for these boats.”  

Another of the eye-catching and game-changing AC75 rules was the opportunity to ‘endplate’, or seal the mainsail onto the deck of the hull (or platform), and this is also still part of the rule. This provides performance gains by stopping air flowing under the bottom of the mainsail, which detrimentally reduces the pressure differential between the windward and leeward sides. It’s this pressure differential that provides the driving force from the rig, so anything that can be done to maintain it will make the boat faster.  

“So, basically we're making the sailplan more efficient by endplating it to the very bottom so that pressure can't leak across the deck from one side to the other, maintaining that differential of pressure on both sides,” said Mickey.  

ac 37 sailboat

“I think that last time a lot of the teams came into the Cup thinking that the double-skin sail was more like a  solid wingsail. This got magnified by the fact that the three previous Cups all saw wings being used. A lot of the knowledge about sail behavior and performance advantages came from this wingsail era, but suddenly it changed back to membranes and soft sails and people needed to change their approach, but – apart from Team New Zealand -- probably a lot of the teams were lagging behind in that switch.”  

One element in the aerodynamic package that has changed is that the rule no longer allows the code zero, a big, powerful headsail that was intended to help get the AC75 foiling in lighter winds. “The initial concept was that the code zero was a bit of a ‘safety-valve’ in case the boats were very sticky in the light [winds]. Nobody had ever seen a foiling monohull at that point, and everybody was concerned about the weight of the boats, and the drag they had in light air.  

“As it turned out, the boats were more efficient than most people thought. And the other factor is that the aerodynamic drag of a big code zero is so prohibitive that it has a very, very small window where it would work.”  

Mickey has no concerns that the boats will be short of sail area as a result of the loss of the code zero. “I think there's enough sail area still available for the boats. So, I think the challenge is always the same; optimize the sails and rig for range. How do you expand the sail range so that when the wind drops two or three knots, or the conditions change and it’s a bit more choppy, we can adapt the sail shape to it. That's where the design space is, and that adaptability is, I think, where we can improve; on the adaptability of the sail shapes and the range of the rig.” If the adaptability of the rig is the biggest opportunity, then what’s the team’s greatest challenge?  

ac 37 sailboat

“I think the biggest challenge is to make sure that the basic principles are looked after. It's very easy in well-resourced campaigns to get distracted by details and to try to do these details very well, but to have the overall concept lacking. So, we have to make sure that the overall concept follows a solid path of how a sail and a rig behaves… and don't forget that it's still a sailboat and it operates in that environment.  

  “So make sure that these basic functions are done very, very well… the sailmakers design experience of how a sail behaves and what needs to be done to make it fast when integrated with the rig. I think it's very important to have a focus on what you're trying to achieve. If you try to copy something somebody else does and you don't really understand the underlying principle of what they're trying to achieve, then you're not any better off. You need to have a path you follow and you need to work that out.  

“You can be sure that people will push the boundary and we will see some wacky stuff. I think we will see people pushing the envelope around the deck, the fairings and how they are integrated with the crew. The aerodynamic drag on these boats is a big deal, so we're going to see a little bit of the Formula 1 focus with an emphasis on drag. I think it's a pretty interesting challenge for somebody like myself, simply because this is one of the few campaigns where the rig and sail aerodynamics is weighted as high as the hydro performance, and that is unusual in our world.  

ac 37 sailboat

“Historically, the America's Cup is all about yacht design and therefore about yacht designers and therefore about the hull shape -- and the sails sort of trundle along… now we’re seeing an environment where it’s a very combined, equally weighted approach, and that comes from the F1 side to a big degree. They're used to that, they're talking about it every day and that's exciting.”

AC37 Preliminary Regatta – Good News and Not so Good News for INEOS Britannia on Day 3

AC37 Prelim D3 Ben Ainslie

Day 3 of the Louis Vuitton Preliminary Regatta and the British team desperately needed to up their game and get some points on the board.

And it was a good news and not so good news day for INEOS Britannia fans.

The good news was that the challenger of record finally have a win on the board.

In their match with the Swiss, Alinghi Red Bull Racing they came off the startline neck and neck, then tacked away and crossed behind Alinghi.

But by the first gate Ainslie took Britannia round with a 4 sec advantage to lead downwind,  and continued to build the lead on each leg,  to take a 33 sec win.

AC37 Prelim Day 2 Ineos Alinghi

So far, so good . . . but this comfortable performance was spoilt in the second race, where the Brits faced much stronger opposition in Italy’s Luna Rossa Prada Pirelli.

Ainslie picked-up a start line penalty and despite a close start had to let the Italians gain a 75m lead to clear the penalty.

That was not helped by a boundary penalty dropping them to a total 190m deficit.

This sort of gift is just something you cannot give to Jimmy Spithill, who took Luna Rossa up the course without error and built a 400m lead by leg 4.

AC37 Prelim D3 Ben Ainslie

The wind was dropping but Luna Rossa continued safely to a 46sec win at the finish.

The errors were small but critical in this matchrace format on the tight course, and this race really defined the INEOS Britannia performance so far.

INEOS Britannia will race France’s Orient Express Racing Team in their final race Sunday.

This really has to be a confident win of the Kiwi doppleganger, for the Brits to go forward with any hope of being a contender.

AC37 Prelim D3 American Magic Rudder

Meanwhile Orient Express Racing Team FRA, bounced back from their Foil Cant System issues of yesterday.

They got a sail-over win after NYYC American Magic were forced to retire, with a rudder rake cylinder issue that brought ‘Patriot’ to a halt before they could start.

The final race of the day saw Emirates Team New Zealand take on Alinghi Red Bull Racing and a split tack start with the Kiwis taking the right and the Swiss going left.

When the two boats came back together, it was a 40m advantage to ETNZ and they capitalised on every leg, winning by 1 minute and 15 seconds.

The Kiwis now have a four win record and will sail unruffled into Sunday’s match against NYYC American Magic having already sealed their place in the final.

The forecast for for Sunday is an increase in wind strength, which may inject some jeopardy into the event, apart from the technical issues!

ac 37 sailboat

Racing starts at 13:00 UK (14.00 CET) every day – 22 to 25 August – and will be screened here on the America’s Cup YouTube channel.

AC37: Challenger Alinghi Red Bull enters America's Cup regatta

Related articles.

A name that has not been part of the America’s Cup series for over a decade will be returning as a new Challenger in the form of the Alinghi Red Bull sailing team.

Red Bull has partnered up with the Alinghi syndicate, which races under the flag of Switzerland’s Société Nautique de Genève. Despite representing a land-locked country, the Alinghi team has won the America's Cup twice – in 2003 in New Zealand and in 2007 in Spain.

"While keeping the winning spirit that has always animated Alinghi, we want for this challenge to do something totally different, totally new, totally fresh," said Alinghi team founder Ernesto Bertarelli.

“With Red Bull we are equal partners in this venture. They will bring their competence, energy and strength in creating performing teams, and we bring our experience in sailing and winning the America's Cup. Alinghi Red Bull Racing will shine a new light on the event," Bertarelli added.

The Alinghi sailing team will benefit from the expertise of the Red Bull Advanced Technologies unit that has powered Red Bull Racing to a total of five Formula One Drivers' Championships and four F1 Constructors' Championships, including the win just secured by Max Verstappen in the last lap of 2021 at the Abu Dhabi Grand Prix.

Fresh from the Formula One final, Red Bull Racing principal Christian Horner commented on the partnership: "We welcome Alinghi Red Bull Racing to the World of Red Bull, and our F1 team is looking forward to helping this new member of our family to succeed […] We will share our experiences, engineering tips, etc. It is a two-way cooperation."

The new America’s Cup team will establish its headquarters in Écublens in the canton of Vaud, Switzerland. Located on the fringes of Lake Geneva, this site will be where the hull of the team’s vessel is to be constructed. 

The crew of Alinghi Red Bull will be made entirely of Swiss sailors, led by Alinghi's GC32 coskipper Arnaud Psarofaghis and mainsail trimmer Bryan Mettraux who will begin training during the winter period.

Alinghi Red Bull joins fellow Challengers INEOS Britannia from the UK against Defender Emirates Team New Zealand in a bid to win the oldest sports trophy in the world. In 2021, Emirates Team New Zealand triumphed against Italian Challenger Luna Rossa Prada Pirelli to win the 36th America's Cup.

More challengers are expected to be announced in the coming months as the entry period runs until July 31, 2022. The final America’s Cup regatta will be held in 2024, with the venue and event dates to be announced by the end of March 2022.

America’s Cup boats: 8 facts about the AC75 and why they’re unique

  • August 20, 2024

The America's Cup boats to be used on the 2024 edition of the event are immensely complicated high tech bits of kit. They might be officially sailing craft but they behave in some remarkable ways

ac 37 sailboat

The AC75 is the class of boat that takes part in the America’s Cup and are arguably the most radical boats the compeition has ever seen.  This type of America’s Cup boat was first used in the 2021 America’s Cup so this is the second event in which these boats have been used.  

The America’s Cup is, fundamentally, a design competition, and successive America’s Cups have featured the most extreme yachts yet – for their time – ever since the first race in 1851.

However, the foiling boats we have seen in the last four editions of America’s Cup racing (the AC72 and AC50 catamarans, and now the AC75 monohulls) do represent a new direction for the highest level of sailing.

There are plenty who argue that this technology is so far beyond the bounds of what most people consider sailing as to be an entirely different sport. Equally, there are those who believe this is simply a continuation of the development that the America’s Cup has always pushed to the fore, from Bermudan rigs, to composite materials, winged keels, and everything in between.

Good arguments can be made either way and foiling in the world’s oldest sporting trophy will always be a subjective and controversial topic. But one thing is certain: the current America’s Cup boats, the AC75s, are unlike anything seen before and are showcasing to the world just what is possible under sail power alone.

1 Unimaginable speed

Topping the 50-knot barrier used to be the preserve of extreme speed record craft and kiteboarders. A World Speed Sailing Record was set in 2009 of 51.36 knots by Alain Thebault in his early foiling trimaran, Hydroptere , and was bested in 2010 by kite boarder, Alexandre Caizergues who managed 54.10 knots.

Only one craft has ever topped 60-knots, the asymmetric Vestas Sail Rocket 2 , which was designed for straight line speed only and could no more get around an America’s Cup course than cross an ocean. Such records are set by sailing an average speed over the course of 500m, usually over a perfectly straight, flat course in optimum conditions.

America’s Cup class yachts, designed to sail windward/leeward courses around marks, are now hitting speeds that just over a decade ago were the preserve of specialist record attempts, while mid-race. American Magic has been recorded doing 53.31 knots on their first version of the AC75 class, Patriot.

Perhaps even more impressive, in the right conditions when racing we have seen some boats managing 40 knots of boatspeed upwind in around 17 knots of wind. That is simply unheard of in performance terms and almost unimaginable just three or so years ago.

The America’s Cup Louis Vuitton Preliminary Regatta will start on Thursday 22 August 2024 and will run through until Sunday…

WATCH: Will the USA’s Radical America’s Cup Design Choices Pay Off?

American Magic’s new AC75, Patriot, has garnered significant attention due to its unique approach. While all the teams are bound…

2 A storm onboard the AC75

Related to the speeds the boats are sailing through the water, particularly upwind, is the wind speeds the sailors will feel on deck.

When sailing, the forward motion affects the wind we experience onboard, known as apparent wind. The oft’ trotted out explanation of how apparent wind works is to imagine driving your car at 50mph. Roll down the window and stick your hand out of it and there will be 50mph of wind hitting your hand from the direction your car is travelling.

So when an AC75 is sailing upwind in 18 knots of breeze at a boatspeed of 40 knots, the crew on deck will be experiencing 40 knots of wind over the decks plus a percentage of the true wind speed – depending on their angle to the wind.

The AC75 crews might be sailing in only 18 knots of breeze – what would feel like a decent summer breeze on any other boat – but they experience winds of around 50 knots.

To put that into context, that is a storm force 10 on the Beaufort scale!

ac 37 sailboat

3 Righting moment changes

The single most radical development of the AC75 is to take a 75ft ‘keelboat’, but put no keel on it whatsoever.

When the then America’s Cup Defender and the Challenger of Record, Emirates Team New Zealand and Luna Rossa Prada Pirelli respectively, announced that the 36th America’s Cup (to be held in 2021) would be sailed in 75ft monohulls, conventional wisdom had it that the boats would look something like a TP52 or a Maxi72 – both impressively high performance keelboats.

By doing away with the keel entirely, the design is now like nothing we have ever seen, particularly when it comes to how dynamic the power transition is between foiling and not foiling.

The boats are designed to foil on the leeward foil, with the windward one raised to help increase righting moment: to help balance the boat. This means that when the AC75 is not foiling they are extremely tippy – much more so than most other boats of the same size.

Essentially, when the wind catches the sails, the boat wants to fall over as there is too much sail area for the amount of weight underneath the boat – something a lead keel usually counters on a yacht or keelboat.

Once the boat is up and on the foils, however, that all changes, as everything to windward of the single foil in the water balances the sails. That means, the hull, the crew weight, the sail and rig weight, and the windward foil, all work to counter the sails.

What all this means is that the boats go from being extremely tippy, to hugely powerful in just the few seconds it takes to get up on the foil. “The [AC75s] are really very tippy pre-foiling and then they go through the transition where they will need to build significant power. Then immediately [once they lift off] you have more stability than, well, take your pick, but certainly more righting moment than something like a Volvo 70 with a big canting keel.

“That change all happens in a very short space of time,” explained Burns Fallow of North Sails, who was one of the team who developed the soft wing concept back when the concept was revealed.

4 ‘Cyclors’ return to power America’s Cup boats

Bak in 2017 Emirates Team New Zealand stormed to America’s Cup victory in an AC50 foiling catamaran which was, by some margin, quicker than any of the other teams.

The most glaring difference was their use of pedal grinders to produce power rather than traditional pedestal arm grinders. ETNZ’s sci-fi style term for their grinders was ‘cyclors’, cyclist sailors.

The idea had actually been tried before in the America’s Cup; Pelle Petterson used pedal grinders on the 12-metre Sverige in 1977. But ETNZ’s set-up now was very different: here it was part of a linked chain of innovations, the most obvious emblem of a radical approach.

One obvious benefit was the greater power output from using legs to pedal, but beyond this it left cyclists’ hands free and allowed the team to use a highly sophisticated system of fingertip control systems, and thus to use faster, less stable foils, and then to divide up crew roles so ETNZ could be sailed in a different way.

When the AC75 was first introduced in 2021, Cyclors were specifically banned by the class rule. However, with a reduction of crew numbers from 11 to 8 in the second AC75 class rule – in use for the 2024 America’s Cup – cyclors are now allowed once again and all teams look set to be using pedal power onboard.

5 America’s Cup boats may not be heading where they point

With the AC75 sailing on its foil, drag is dramatically reduced, vast amounts of power can be generated and so speeds rapidly increase. But the foils can serve another purpose too.

In order to be able to lift each foil out of the water, the foil arms must be able to be raised and lowered. Hence the foil wings, which sit at the bottom of the foil arms (and are usually a T or Y shape), do not always sit perpendicular to the water surface and the AC75s often sail with them canted over to something nearer 45º to the surface.

The further out the leeward foil arm is canted – essentially more raised – the closer the AC75 flies to surface and, crucially, the more righting moment is generated as the hull and rest of the boat gets further from the lifting surface of the foil.

There is another positive to this: as the lifting foil is angled, it produces lift to windward, which can force the boat more towards the wind than the angle it is sailing.

Due to this negative leeway (as it is known when a foil creates lift to windward) the boat can be pointing at a compass heading of say 180º but in fact will be sailing at eg 177º as the foil pushes the boat sideways and to weather, essentially sailing to windward somewhat diagonally.

ac 37 sailboat

6 The foils are heavy. Very heavy.

As the foils work to provide stability to the boat (when it is stationary both foils are dropped all the way down to stop it tipping over) and to provide massive amounts of righting moment, they are incredibly heavy.

A pair of foil wings and flaps (excluding the one-design foil arm which attaches them to the boat and lifts them up and down) weigh 1842kg. To put that into perspective, the entire boat itself with all equipment (but without the crew) weighs between 6200kg and 6160kg. So the foil wings at the base of the foil arms are nearly ⅓ of the total weight of the boat.

It is partly due to this that you will see some teams with bulbs on their foils. If you decide to go for a skinny foil wing (which would be low drag and so faster) then there will not be enough volume to cram sufficient material in to make the foil weigh enough. So some teams have decided to add a bulb in order to make it weigh enough but to also keep a less draggy, slimmer foil shape.

7 Sails can invert at the head

As with everything on the AC75, the mainsail was a relatively new concept when the boat was first announced. It consists of two mainsails which are attached to both corners of a D-shaped mast tube. This has the effect of creating a profile similar to a wing.

It is well established that solid wing sails are more efficient at generating power than a soft sail and for this reason solid wings were used in both the America’s Cup in 2013 and 2017. But there are drawbacks with a wing: they cannot be lowered if something goes wrong and require a significant amount of manpower and a crane to put it on or take it off a boat.

One reason a wing makes for such a powerful sail is that the shape can be manipulated from top to bottom fairly easily with the right controls. With the AC75 the designers wanted a sail that could have some of this manipulation, produce similar power but could also be dropped while out on the water. The twin skin, ‘soft wing’ is what they came up with for this class of America’s Cup boat.

In addition to the usual sail controls, within the rules, the teams are allowed to develop systems for controlling the top few metres of the mainsail and the bottom few metres.

What this means is that the teams are able to manipulate their mainsail in a number of different ways to develop power and control where that power is produced in the sail. But it also means that they have the ability to invert the head of the sail.

Doing this effectively means ‘tacking’ the top of the sail while the rest of the sail is in its usual shape. The advantage here is that instead of trying to tip the boat to leeward, the very top of the sail will be trying to push the boat upright and so creating even more righting moment. The disadvantage is that it would come at the cost of increased aerodynamic drag.

We know that a number of America’s Cup teams are able to do this, though whether it is effective is another question and it is very hard to spot this technique being used while the boats are racing at lightning speeds.

8 America’s Cup meets F1

A new America’s Cup boat is a vastly complex bit of kit. Each team has incredibly powerful Computational Fluid Dynamics (CFD) software packages and simulators in order to try to understand the various gains and losses.

To make these simulators and computer projections as accurate as possible each team has been getting as much data as they can over their three year development cycle.

In the case of this America’s Cup it does seem the development process is genuinely getting closer to Formula 1 (albeit with smaller budgets than a modern F1 team has behind them).

INEOS Britannia have been work alongside the all powerful Mercedes F1 team (both of who are backed by INEOS) and have been open about how much this has helped their development process and after a relatively small amount of collaboration in 2021 the British team and Mercedes have created a much tighter relationship for the 2024 America’s Cup .

But the British team is not alone. When two-time America’s Cup winner, Alinghi announced they would be coming back to the event after some years on the sidelines, they also announced their own tie-in with current F1 World Champions, Red Bull Racing, to for Alinghi Red Bull Racing .

“It’s really similar to F1,” explains Mercedes Applied Science Principal Engineer Thomas Batch who has 11 F1 titles to his name and is was with INEOS in Auckland 2021. “Certainly in this campaign the technology is close to what we have in F1.

“In terms of raw sensors on the boat you are probably talking in the 100s but then we take that and we make that into mass channels and additional analysis with computational versions of those channels that we then analyse and get into in more detail. So you are looking at 1000s of plots that we can delve into [per race or training session].

“That level of data analysis and then feedback with the sailors is very similar to working with an [F1] driver.”

12 - 27 October 2024 The America's Cup is a competition where there's no room for second place—it's a winner-takes-all event that has been this way for over 170 years. In October 2024, the Defender, Emirates Team New Zealand, will compete against the winner of the Louis Vuitton Cup (Challenger Selection Series) in a 13-race match series. Each race will be a direct battle between the two teams, with the victor earning one point and the loser receiving none. The first team to accumulate seven points will be crowned the Defender of the 38th America's Cup.

All six America’s Cup teams took part in the Louis Vuitton Preliminary Regatta, racing their new AC75 yachts. The competition began on August 22nd and featured four days of match racing to identify the two fastest teams. These were Emirites Team New Zealand and Ineos Britannia. They advanced to a winner-takes-all final match race on the fourth and final day to determine the event's ultimate victor, which was Emirites Team New Zealand. AC37 is indeed going to be exciting!

America’s Cup 2024: What are the AC75 boats and how do they work?

The world’s oldest international sports trophy, best yachtsmen and cutting-edge design and technology come together in Barcelona for the 37th edition of the America’s Cup.

Five boats – from Italy, the United States, Britain, Switzerland and France – will spend the coming weeks racing in the Mediterranean waves to decide who will earn the honour of trying to dethrone the mighty Emirates Team New Zealand for the Auld Mug.

As the two-time defender, the Kiwis chose Barcelona’s choppy waters as the venue and helped establish the rules and boat design for this edition. They also get a guaranteed spot in the final, to be held in October.

The results of three years of work and massive investment will now be put to the test.

“It is starting to get serious in a hurry. We are now racing for keeps,” Ben Ainslie, skipper of British team Ineos Britannia, said.

Here is everything we know about the boats – AC75s – that will be racing...

“Because Barcelona is quite a lightwind venue, you don’t actually want to design foils for going at 60 knots. Acceleration and manoeuvrability are more important. So in terms of top speeds I don’t think we will see anything radically different from the top speeds we saw in the last Cup in New Zealand. Somewhere around 50 knots. But these boats would smash the boats from last time if they actually raced. I guess it’s like Formula One cars. The new boats are much faster over a lap, but they gain that time through cornering speed and acceleration rather than on the straights.” – Giles Scott (Head of Sailing, Ineos Britannia)

This is the second iteration of the AC75 after they were also used in New Zealand at the 36th Cup.

The “75” in AC75 stands for 75-feet, the length of the boat. The boats are 16 feet wide.

The AC75 is a “foiling” monohull, which means it has only one hull which lifts up out of the water on hydrofoils - or “flies” - when the wind gets above a certain speed, typically around six knots.

Although the boats look very similar, there are various changes since the last Cup.

The rules have been tweaked partly to improve light-wind performance (frankly, it looked silly when the most technologically-advanced boats in the world fell off their foils in light winds in New Zealand in 2021, bobbing around helplessly) and partly to reduce crew numbers from 11 to eight for cost and performance reasons.

The move to reduce the crew means cycle power is again legalised, and “cyclors”, the hybrid sailor-cyclists introduced by Team New Zealand in Bermuda in 2017, return.

Length: 75 feet

Width: 16 feet

Height: 26.5m from the deck

Weight: 6,200kg

Max crew weight: 700kg

Top speed: 50 knots

Eight-man crews

Crews have been reduced from 11 to eight since the last Cup.

No boat will feature anyone crossing during manoeuvres. That will be the biggest visual change for spectators. Everyone stays where they are, with four sailors on each side of the boat.

The crews sit low in their pods, out of the airstream with only their helmeted heads exposed.

Each team is slightly different in how and where they deploy their eight men, but every team has a helm, a trimmer and two cyclors on either side of their boat.

The British team are unique in that their trimmer-pilots sit at the back of the boat in the aft pods, with the two cyclors between them and the helms in the forward pods.

The cyclors’ role is to provide hydraulic power to the boat’s systems, from the foil arms to the mainsail.

The Americans are outliers in that their cyclors are “recumbent”, meaning they are sitting/lying backwards, facing up towards the sky. This position sacrifices some power - around 10-20 per cent compared to traditional cyclists - but it does free up their hands to perform secondary functions.

But it is likely that on every boat, certainly the British one, the cyclors will all have secondary roles. On Britannia, two of those roles are critical functions but not necessarily sailing-skill oriented (these might be suitable for former rowers who do not have sailing backgrounds). Two you would want to put sailors in there.

F1 crossover

The crossover between America’s Cup and F1 is becoming ever greater. Not for nothing is sailing’s most elite competition becoming known as “F1 on water”.

Carbon-fibre composites, structural analysis, hydraulic systems, control systems, electronics, data analysis, hydrodynamics and aerodynamics are just some of the overlapping areas.

Ineos Britannia have a partnership with Mercedes F1 via joint owners Ineos. The sailing team has offices in Brackley and hundreds of Mercedes staff have been seconded to the sailing project. James Allison is Chief Technical Officer of both teams. Geoff Willis is Technical Director of Mercedes-AMG F1 Applied Science and INEOS Britannia.

Each boat is equipped with a pair of T-foils, on the end of “cant arms”. Around the size of an ironing board, the foils on the AC75 are capable of lifting a seven-tonne boat out of the water.

As in the last Cup, the mainsail is “twin skin”; two membranes held together. Teams are allowed to “endplate”, or seal the mainsail onto the deck of the hull (or platform). This provides performance gains by stopping air flowing under the bottom of the mainsail, which detrimentally reduces the pressure differential between the windward and leeward sides.

The AC75 rudder allows the boat to change pitch, or trim, by providing lift. This change in pitch moves the stern of the boat closer to the ground, which increases the angle of attack on the main foils. The foils provide lift, which moves the entire platform up.

It appears that foiling monohulls are here to stay. At least for The AC. The technology works reasonably well, and is a way of keeping with monohulls (catamarans are faster foilers). Indeed, foiling seems to be the last word in scalable sailboat performance. So, it's only natural for the AC to embrace it. But it seems different from the 12 meter class old days. I find myself more and more indifferent to the competition, as it seems to be dominated by a small mafia of sailors who seem to be completely mercenary. I suppose this is at least partly because most sailors will never own or even sail on a foiler. They are incredibly fast, but must be kept extremely light in order to work.

True enough.On the other hand the lifting foils on a cat can have a greater amount of lateral separation from the rig and the windward hull is even further away,which helps the righting moment.I would be very interested if anybody could dig out reliable comparative aero drag figures for both types.I don't doubt it would be too confidential to share and have no realistic expectation of seeing solid data.  
Flotation said: ↑ Why would catamarans be faster foilers by definition? As speeds increase air drag gets more important and cats drag a whole lot of draggy structure trough the air. Click to expand...

DogCavalry Senior Member

When not on the foils, monohulls still need ballast, to not just flop over. So presumably the cat is still lighter, once the boat is big enough that constant motion from the crew isn't enough to keep it upright.  
Must agree though. I simply don't care anymore. It hasn't been relevant to the art of making seaworthy boats for a very long time. If they set the dates a year and advance, and ran the races absolutely without regard for the weather that day, I'd pay some attention. I'd love to see some of these decadent monstrosities fighting it out in sea state 5. Or cowering in port while some folks in a real boat take it all.

I have an idea that I already launched on Sailing Anarchy the day they issued the new protocol. Protocol for the 37th America’s Cup https://forums.sailinganarchy.com/index.php?/topic/227617-protocol-for-the-37th-america%E2%80%99s-cup/&do=findComment&comment=7732586 Here is the idea, It's bloody simpel. Use photo electric Voltcells molted into the deck as an extra bonus for battery 60 volt charge. Use the same cells of the solarchallege if you do not want to do research, but in case of endless financial supply, invent a better one and be usefull for the planet. They reacted somewhat positive maybe Dalts is considering to take the extra option into the final, not draft, version. He stated there were al lot of days not sunny in for instance Portsmouth. Also the final location in the cup, Auckland has a lot of not sunny days. My idea is as follows but has to be described in the regattarules. Make a green flag when lurking (extra shore power ) is prohibited. As counter argument they came up with the extra weight disadvantage. That's not a problem if every team is obliged to do so. Most effective PV cells might be to costly and too vunerable for water leaking. How do my fellow engineers feel about this plan? It might safe the weight of grinders in the best case. Looking forward to constructive remarks....

sharpii2 said: ↑ For two reasons: 1.) No.ballast, so less weight, and 2.) Greater distance between the main lifting foils. Also, two slim hulls are easier to push through the air than one wider one, even if the beams of the two narrow hulls add up to be the same as the wider hull. Click to expand...

5 Best Sailboat Air Conditioners

Best Sailboat Air Conditioners | Life of Sailing

Last Updated by

Daniel Wade

June 15, 2022

It's quite easy to imagine yourself anchored near an island, sipping juice from a young coconut without a worry in the world while aboard your sailboat. But complete comfort can only be possible if your sailboat is fitted with one of the best air conditioners (ACs).

Sailing in the hot scorching sun or tropical heat is great. But the reality that you have to deal with such hot weather and the possibility of suffering from heatstroke can be some of the major drawbacks. Sure, you can take a dip into the water or take a shower to mitigate the sweltering heat and sweat but this can only work for a few minutes if not seconds. As such, nothing is more comfortable than having your sailboat fitted with high-quality air conditioning if you want to get rid of that heat.

If you, like most of us, do not fare well in sweltering temperatures, investing in one of the best sailboat air conditioners should be the right thing to do.

The Importance of Having a Reliable Air Conditioner on Your Sailboat

Sailing, especially in the summer, generally means that you'll have to deal with temperatures on the north of 95 degrees Fahrenheit and humidity that's close to 90%! Sailing in such temperatures is hands down challenging. Add to the fact that it can be extremely cold at night or during winter, and you have several reasons to have a reliable sailboat air conditioner installed on your vessel.

Honestly speaking, sailboat air conditioners are quite costly, especially for those of us who are cruising on a budget. However, their importance in ensuring that you have an enjoyable sailing experience and do not suffer from heatstroke can never be downplayed. With a reliable air conditioner, your sailboat will be comfortable, cool, and air will circulate in your boat, which is essential in preventing mold.

Factors to Consider when Choosing the Best Sailboat Air Conditioner

Besides being expensive, an air conditioner plays a crucial role in making your vessel more comfortable and enhancing your sailing experience. You certainly do not want to end up with a poorly working air conditioner. This is exactly why you must have a well-thought-out plan when in the market for the best sailboat conditioner.

Here are things to consider.

Size and Layout of Your Sailboat

The right air conditioner system is one that can efficiently cool or arm the entire boat without struggling. The larger the boat, the more powerful the air conditioner system you will need. Of course, you'll need more than one unit if your boat has several cabins. You'll also need space for an engine room if you choose a split air conditioning unit.

The Size of the AC Units

Modern AC units are designed to be lightweight, easy to set up, and install. These are some of the most important features to consider when choosing an appropriate AC for your vessel. You do not want to end up with a bulky unit that may not fit in your vessel.

The Air Conditioner's Power Requirement

One of the most important things to consider when choosing the best sailboat air conditioner is the unit's power requirement. Generally, you need to have generous battery banks, a powerful inverter, and an efficient source of power such as a generator or solar panel.

Most air conditioners are noisy when they operate and this can be irritating. You should go for an AC unit that is less noisy, especially if you're a light sleeper.

Your Planned Sailing Ground

Weather conditions generally affect how an AC unit will work. Of course, the unit will work a lot harder if you are sailing in hotter climates than when sailing in colder climates. With that in mind, your preferred sailing ground and its climates will determine the appropriate BTU (British Thermal Unit) that you require.

Budget and Maintenance

Keep in mind that sailboat air conditioners can be costly, so you need to consider your budget. Again, it's important to ensure that the unit is well-maintained to operate effectively without breaking down.

Without wasting much of your precious time, here are the best sailboat air conditioners for 2020.

LOUIS VUITTON 37TH AMERICA'S CUP BARCELONA

Welcome to the Louis Vuitton 37th America’s Cup taking place between August and October 2024 in the beating heart of beautiful Barcelona, the capital of Catalonia and one of the most visited cities on planet Earth. Situated around Port Vell and along the beach to Port Olímpic, the sailing world has made Barcelona their home for what promises to be one of the most intense America’s Cups in the event’s 174-year history.

WHAT IS THE AMERICA'S CUP: THE RACE WITH NO SECOND PLACE

It is the oldest international sporting trophy – dating back to 1851 – and stands as one of the hardest sporting endeavours. The New York Yacht Club, one of the most prestigious clubs in the world, held the trophy for 132 years before losing it in 1983 to Australia. Since then, the Cup has only been won by teams from the United States, Switzerland, and New Zealand. The current Defender of the America's Cup is Emirates Team New Zealand, representing the Royal New Zealand Yacht Squadron.

WHERE: BARCELONA, CATALONIA, SPAIN

“Like a jewel in the sun” was how Montserrat Caballé and Freddy Mercury described Barcelona in their famous song about the city. The cosmopolitan capital of Spain’s Catalonia region–known worldwide for its art, architecture and vibrancy–is shining even brighter as preparations are well underway to welcome the Louis Vuitton 37th America’s Cup and its teams. All the teams’ bases are located within the Port Vell area and surrounded by the America’s Cup Race Village where tens of thousands of spectators can be accommodated daily. The racecourse, just outside the port entrance breakwaters, is set in front of significant fan zones, beach viewing platforms and a hospitality area to provide the perfect vista.

WHEN: AUGUST – OCTOBER 2024

The Louis Vuitton Preliminary Regatta starts on the 22nd August and the Louis Vuitton Cup (Challenger Selection Series) will follow, leading up to the Louis Vuitton America's Cup Match starting on the 12th of October 2024. During 2023 and early 2024, three preliminary events will be held in Vilanova i La Geltrú, Jeddah, and Barcelona. In June 2023, all teams set up their bases and are training in Barcelona. Further details and race schedules will be published in due course.

WHO’S RACING: Emirates Team New Zealand, INEOS Britannia, Alinghi Red Bull Racing, Luna Rossa Prada Pirelli, NYYC American Magic and Orient Express Racing Team

The holders of the America’s Cup are Emirates Team New Zealand representing the Royal New Zealand Yacht Squadron, but some strong competition is coming for them. INEOS Britannia, the ‘Challenger of Record’ from the United Kingdom, are in charge of the Louis Vuitton Cup (Challenger Selection Series) to decide who will race against Emirates Team New Zealand for the trophy. The unique format of the Cup sees the Defender of the trophy automatically entitled to race in the final Louis Vuitton 37th America's Cup Match whereas the Challengers will undertake a series to find the top yacht to take on the New Zealand team. The additional confirmed entries are: Alinghi Red Bull Racing from Switzerland, Luna Rossa Prada Pirelli from Italy, American Magic New York Yacht Club from the USA and Orient Express Racing Team from France.

WHAT BOATS: AC75 AND AC40

The AC75s are the pinnacle of foiling monohull yachts. Created for the 36th America’s Cup, they are a technological leap ahead of typical yachts as Formula 1 is to your daily driver. With foils that lift them out of the water and enable the yachts to generate so much momentum that they sail 4x faster than the wind.

For the Louis Vuitton 37th America’s Cup, the second generation of the AC75s will be even faster with wider foils and refinements all over. Eight crew will be aboard and some of the finest sailing talent will be charged with racing them.

The AC40s, meanwhile, are the boats used for the UniCredit Youth and Puig Women's America’s Cup events and as training vessels for the main teams competing in the Louis Vuitton 37th America’s Cup. Smaller but no less potent, with a four-person crew, these pocket-rockets were launched to much fanfare in September 2022, and their performance has been astonishing.

Event Format

The Louis Vuitton 37th America’s Cup Barcelona will comprise several events that will eventually culminate in the October 2024 Match. The Preliminary Regattas will serve as warm-up races ahead of the Louis Vuitton Cup (Challenger Selection Series), which decides who moves on and faces the Defender for the ultimate prize. The very best female and youth athletes from around the world will be thrust into America’s Cup level racing for the UniCredit Youth & Puig Women's America's Cup events, paving the pathway to the future of the America’s Cup itself.

LOUIS VUITTON 37TH AMERICA'S CUP MATCH: STARTS 12 OCTOBER 2024

Each race will be a match race between the two teams. The winner of each race scores one point, the loser scores no points.

Video shows 37 passengers evacuate from New York City ferry after fire breaks out

Portrait of Anthony Robledo

About 37 passengers were evacuated from a New York City ferry boat when a fire broke out onboard .

The engine fire began around 4:37 p.m. local time, as the "Father Mychal Judge" ferry boat headed from Manhattan toward Jersey City along the Hudson River, according to New York Waterway spokesperson Adam Pockriss.

First responders transported 37 passengers onto a separate New York Waterway vessel named the "Frank Sinatra," Pockriss told USA TODAY Thursday. No injuries were reported as a result of the blaze.

The fire was extinguished 3 or 4 minutes after it started with the ferry boat later taken back to a work dock to be repaired, Pockriss added. The cause of the incident has not yet been determined.

Passenger said he considered jumping into the water.

Cary Broder rode the ferry that day as part of his work commute when the fire broke out, according to local station WPIX . He said people remained calm despite being "obviously scared."

"I looked behind me, and there were orange flames shooting out of the back of the boat," Broder told the TV station. "I was fairly certain we were going to have to jump into the river, actually."

Despite the frightening incident he has no intentions to stop taking the ferry, which saves him an hour from his commute to work, the station reported.

"I was a little bit panicked, you know, and there were a bunch of people gathered on there, and you know, I was just trying to get off the boat onto the other one, and then it wasn’t until afterward I realized I was like, oh, you know, my bike’s still on there," he told WPIX.

Air Conditioning for Sailboats

Long-term test compares ac choices.

ac 37 sailboat

One of the great joys of sailing is the state of near nakedness (literal and figurative) to the wind, air, and sea-and the wisdom that comes with it. From that perspective, climate control seems antithetical to the sailors art. But being Practical Sailor (not Philosophical Sailor) we recognize that even the hardiest round-the-world racers seek temporary refuge dampness, cold, and heat. And for one looking to make the transition from the landlubbers life in temperate climates to full-time cruiser in the tropics, the idea of air-conditioning-despite its huge power demands-is alluring.

Today’s air-conditioning units are lighter and more power efficient than they were ten years ago, but they are still relatively expensive, regarded as luxury items on most boats. The expense of a professionally installed unit on a 35-footer can be as much as a new set sails.

Whenever you are plunking down that much money on a piece of gear, the first question that comes to mind is durability. How long will it last? So, in this, our first in a series of articles on climate control well look at types of air-conditioning and prospective life spans in the real world. (For those who are headed northbound and exploring heat options see Playing it Safe with LPG Heat , Practical Sailor , December 2015).

What We Tested

This long-term comparison focused on two products from Dometic, a world leader in this field-the Dometic CruiseAir 6,700 BTU portable air conditioner and the Dometic 10,000 BTU Turbo Air Conditioner. The units were chosen as representatives of two popular types of integral air conditioning units designed specifically for cruising boats, and were confident that most of our findings can be applied generically to each type. To put these two units into context, we compared their specifications, performance, and attributes to those of portable air-conditioners designed for home use but often used by live-aboard cruisers. A fourth type of air conditioner, the split gas system, which allows separate installation locations of the compressor (usually in the engine space) and the condenser coils and fans, will be looked at in a future article. A fifth type, the RV-type permanent roof-top (or hatch) mount is only really suitable for house boats, or boats that are permanently moored to a dock.

Both systems were installed on the same boat-a PDQ 32 – for an extended period. PS tester Drew Frye, who carried out the testing, has several years of experience using with each of these units on board. For comparison sake we included a portable window unit and a portable ducted air-conditioner, readily available at local home supply stores. Since we did not test the non-marine products, we relied on manufacturer supplied data for comparison.

How We Tested

Along with durability, noise and efficiency are the key concerns for most buyers. Using a calibrated decibel meter we took multiple noise readings from the two air conditioning units at a distance of one meter. We took current readings using a Fluke multimeter to compare energy efficiency and peak current loads. Finally, we observed any other notable differences in performance. The data is recorded in the adjacent tables.

Observations

Without question, portable units are cheaper than fixed units. The CruiseAir 6,700 BTU is no longer in production, but Pompanette makes a similar 6,000 BTU unit available from West Marine for about $1,200. Contrast this to $2,200 plus $1,200 in installation parts and materials for the Dometic Turbo 10000 BTU unit. Fitting the ducts and installing hardware for the Turbo can add two days to the DIY job. If you opt for a professional installation, this can raise the total cost to more than $5,000. The expense of a professionally installed permanent AC is a little less painful when you consider that the AC will increase the boats resale value-especially in warmer climates.

Is a DIY installation practical for a permanently installed AC? Sure, if you’re prepared to run wires and duct work and install through hulls and plumbing. The vendors say it can be done in an afternoon, and this is possible for skilled workman in an ideal situation. However, if the job requires complicated ductwork, allow a day for planning and three full days for installation. If you do decide to do your own installation, be careful not to compromise any structural bulkheads when cutting out passages for ductwork.

Air Conditioning for Sailboats

Follow the instructions rigorously. We have seen many botched installations, both amateur and professional, almost always because the installer did not follow the instructions. To save money on ductwork, buy the insulated duct and inlet/outlet fittings from a home improvement store or an RV store rather than from the manufacturer or a marine equipment supplier.

Floor mounted portables, connected to the outdoors via flexible ductwork, are another option. These are less expensive, only $250-$500 for comparable sizes, but they are still bulky, and they must be secured while the boat is underway. They are not a long-term solution for the mobile cruiser looking for maximum efficiency, but for the low budget cruiser stuck on the dock they are an affordable alternative to sweltering.

Air Conditioning for Sailboats

Avoid single-hose models. These draw cooling air only from inside, and exhaust hot air out through a duct. Since the air within the boat is often hotter and more humid than the outside air, this can reduce the cooling efficiency by as much as 50 percent.

A dual-hose unit recirculates indoor air and also draws air from outside, which improves efficiency significantly. Dual hose units are all greater than 10,000 BTUs. Some require a drain hose, while others evaporate the water into the hot air stream. Some can also operate as high capacity dehumidifiers.

Noise. A permanently installed air conditioner runs on seawater instead of air cooling, eliminating the often noisy cooling air fan required of all portable units. Testers installed the Dometic Turbos compressor and circulating fan inside one of the PDQs salon settees. With the settee seat cushions in place, the unit was very quiet-air hissed through the vents and the compressor emitted a low rumble.

The noise difference is considerable. Testers recorded 67 decibels for the installed Dometic Turbo vs. 75 decibels the smaller portable CruiseAir. Remember that a 10 decibel increase represents ten times the sound energy-so the difference is significant.

Tone. The sound pitch can also make a difference. The installed Turbo was lower in pitch and less intrusive than the CruiseAir. Quiet conversations were nearly impossible when the CruiseAir was running, while the noise of a permanently installed AC is can be nearly unnoticeable if installed correctly. Since the industry sound rating system is not directly comparable our own ratings for installed units, we did not rate the untested units for noise. Experience tells us that the standup and window portables will be closer to the hatch-mounted CruiseAir in terms of noise.

Distribution of cooling. With a portable air conditioner-any type-the person sitting next to it freezes. Distribution through the cabin can be aided by fans, but it will always be uneven. With installed air, vents take the air wherever you want it. However, it is important that area of the supply vent inlets falls within a recommended range. If a vent is too small efficiency suffers. If the inlet area is too big, the flow of cooler air is reduced.

The return volume must also meet the manufacturers minimum requirements, and the return inlet should not draw air from the bilge or engine space, which would not only spread odors and be inefficient, but also present a hazard.

Maintenance. The portable units require no maintenance, other than annual air filter cleaning. A permanent, central air conditioner requires regular raw water strainer cleaning, every 8 to 100 hours, depending on the amount of sea grass and nettles in the water. An external strainer is also required. This, too, needs to be checked for blockages, especially in high fouling areas.

Durability. The Dometic CruiseAir portable survived 18 years of seasonal use without complaint. Frye defied manufacture warnings, leaving it in place during many coastal passages on his catamaran, since it was too heavy to reasonably move and occupied too much space in the cabin. He lashed it down tightly, but that didn’t save it from spray and occasional green water. In the process of moving it, it took a few hard knocks. Eventually, the clamps on the leveling mechanism began to slip, but they were easily replaced with pins that were fabricated from fiberglass tent poles.

Weight. Excess weight is always a concern for sailors. The Pompanette 6,000 BTU unit weighs 53 pounds and the Dometic Turbo 10,000 BTU weighs 47 pounds-plus 17 pounds worth of installation parts (64 pounds total). The added weight of the installed unit is carried much lower, reducing pitching and lowering the center of gravity.

Storage Space. The compressor and condenser coils will occupy one small locker, and you’ll give up parts of other lockers for the duct work. This is the time for that house cleaning you’ve been putting off. Portable units require space when stowed for sailing, preferably where they are out of the way.

Power Requirements. The Pompanette 6,000 BTU portable draws 17 amps to start and 6.9 amps running. The Dometic Turbo, 10,000 BTU draws 14.5 amps to start and 6.7 amps running. It incorporates Dometics Smart Start capacitor and controller to reduce load spikes during start-up. The Avallon 12,000 draws a whopping 10.8 amps running, pressing the maximum safe running load of a 15 amp circuit. Clearly, the Dometic unit is the most efficient, and that translates not only into lower power bills, but also into reduced installation complexity. The Dometic, aided by the smart start controller is easily served by a 15-amp circuit, while the Avallon portable is bumping right up against the maximum.

Inconveniences. Carrying a 55-pound AC unit around the side decks, on-and-off the dock, and down below can be dangerous. Even with two people, getting it down through the companionway is still tricky. What is the cost of a single serious injury? When the unit is stored below for a foul weather passage, it must be well secured and takes up valuable space. If left in the deck hatch during fair-weather sailing, it blocks the view, blocks natural ventilation through the hatch, and snags every sheet that comes near it.

No matter how carefully fitted, hatch units leak rainwater during squalls. Because the close proximity to humid air where they fit through the hatch, most drip condensation. Window units and dual hose units also have concerns.

The only inconveniences of installed AC are opening the seacock and cleaning the raw water strainer. Locate both so they are easy to access. The strainer should have valves on both sides to reduce water spillage. The seacock should be closed when not in use (safety) and for 24 hours every few weeks. Closing the seacock for 24 hours prevents marine growth by eliminating oxygen and by allowing the concentration of copper ions in the water, leached from the copper coil, to reach preventative levels.

Hatch Mounted Units

A step above home store window units, hatch mounted units are a good temporary solution for dockside living while your moored to terra firma doing boat work or rebuilding the cruising kitty.

Dometic CruiseAir 6,700 BTU

We knocked this one around, it took green water right over the top several times (not while running), and though noisy and annoying to have on deck, it just kept running. I doubt many users abused theirs any more, although they may have more hours on them.

Bottom line: Recommended as a second-hand purchase.

Pompanette 6000

Very similar in size and weight to the CruiseAir, we’ve observed them on other boats but not studied them in depth. Those users we interviewed reported zero mechanical problems.

Bottom Line: Consider saving up for installed air.

Installed Air Conditioning

This is the option best suited for long-term cruising, because all of the critical components remain below decks protected from the elements. This feature is especially important for saltwater sailors. The premature failures with installed air systems that we know of stem from installation shortcomings, usually in the raw water suction design.

High intake loops that collect air result in unreliable operation. Oversized water pumps cause premature wear on the coil-bigger is not better in this case. Stray current can eat the cooling coil on the inside, and water leaks can drip seawater on the cooling coil, rotting it from the outside. Low voltage due to undersized wire or poor connections can strain the compressor. Properly installed, the unit should be as reliable and durable as a shore-based unit.

Dometic Turbo DTU 10 10,000 BTU

Dometic dominates this field with several lines of air conditioners to meet specific needs. Its smallest unit is the 3,500 BTU Cuddy, we opted for the 10,000 DTU 10 model.

This unit is quiet and efficient. Although the installation is time-consuming, the several days of boat yoga are well worth it. The very low power draw is a big bonus, allowing us to stay at marinas with modest power supplies.

A DIY installation requires good power tool skills and common sense (see aforementioned caution about penetrating structural bulkheads). It will likely require several days of steady work, or you can pay a contractor $1,000-$2,800, depending on the complexity of the installation and location of your boat.

Bottom line: Installed air is certainly the Best Choice, if you have either the DIY skills to do it right, or the dollars to hire someone.

Portable Uprights

There are dozens of brands of upright, dual hose-air conditioners. Friedrich is one brand that tested well with Consumer Reports, but their test field was limited. Our advice if you go this route is to compare warranty coverage and buy from a reputable supplier.

Avallon APAC120S

The advantage of caster-mounted units is that, unlike hatch mounted portables, you don’t have to lug them above and below decks. When you get the urge to sail they can be wheeled into a corner and secured, although they still eat up space. They are generally very quiet. Because they use a different BTU scale, a 12,000 BTU unit is closer to 5,500 BTU.

Finally, although they claim to evaporate all of the condensate back into the hot air exhaust, we still observed a few ounces of condensate on the most humid days. There is a pan with a sensor-remember to check it daily.

Bottom line: If you need quick AC for summer, this is a good solution while you make up your mind.

Window Units

Window units are clearly the shoestring sailors choice. Look for familiar brand names with good warranty coverage. Most today come with a remote control, which comes in handy.

Kenmore 10,000 BTU (#77060)

A dime a dozen, these are a cheap solution for the boat that spends a lot of time at the dock. We’ve seen them installed in companionway hatches using modified hatch boards, and over deck hatches, adapted to fit using some manner of home-made carpentry.

The former is more compatible with the design since the faceplate is meant to be in the room. There is also a YouTube video showing on how to modify one of these to operate below decks (although it requires quite a bit of metalwork).

Costing as little as $120 on sale, these can be the bargain solution for a small boat in a warm climate. Stowability and durability-especially in a marine environment-are the biggest drawbacks.

Bottom Line: A window unit can be a cheap, short-term solution while you make up your mind.

Conclusions

Portable air conditioning units can be durable and reliable, but they are inconvenient. Installed air conditioning adds considerable expense, particularly if professionally installed, but there is some recovery in increased resale value if properly done.

Generally these units are brought into service when the boat is dockside for long periods of time. If you are on the move between marinas – the stow and set-up routine with a portable can get tedious. But if you are held captive in one spot by circumstances and need some relief from the heat and stillness-a window mount or upright dual-hose will civilize your summer.

Stay tuned as we dive deeper into the world of compressors and coils and various options among split-gas systems.

Air Conditioning for Sailboats

Portable air conditioner can meet the needs of a casual cruiser, but long-term cruisers in tropical climates, especially those with boats greater than 40 feet long, will be better served by installed systems.

Air Conditioning for Sailboats

Nearly all marine air-conditioning problems can be partly traced to poor installation. A key step is to create a schematic that maps out the wiring, plumbing, ducts, and vents. Due to the potential fire risk with these systems, if you have doubts about wiring or fuses, you should consult an electrician. Although you don’t need to be an expert to succeed with a DIY installation—it helps if you are a jack of all trades. And you need to do your homework.

1. A Fein Multimaster simplifies cutting in close quarters. Be careful not to compromise structural bulkheads or liners. 2. Measure twice, cut once. An inlet vent, mounted low in the main saloon fits snugly in its cutout. 3. We fabricated some of the plenums, transitions, and elbows, others were meant for use with clothes driers. 4. An above-the-waterline loop in the cooling water outlet (white hose) prevents backflow into a heeled boat. 5. Glue-on studs are a big help if you cannot through-bolt. These studs are from Duckworks. Weld Mount is another source. (See “ Glue-on Fasteners ” PS July 2017).

Air Conditioning for Sailboats

Properly plumbing the AC system is one of the most important installation tasks, not only from a functional standpoint, but also safety. In order to meet the American Boat and Yacht Standards for through hulls, the seacock needs to be able to withstand 500 pounds of static force for 30 seconds. This typically calls for a flanged base that is supported with screws or through-bolts. A backing plate that incorporates studs is one of the most sensible ways to meet the standard because it avoids the need for additional holes in the hull.

1. The home-made backing plate assembly is tested before gluing, from left: long screw used for clamping during gluing, UL certified Marelon through-hull, the assembled seacock and backing plate. 2. The backing plate with studs is clamped in place as epoxy glue cures. 3. A t-connector simplifies draining for winterizing, ensuring no low spots. 4. The water should rise smoothly from intake, through the strainer, to the pump. If any air pockets exist, the pump will not prime after a short peried of sailing (waves drive air into the pipes and the pump cavitates).

One suggestion, if you are using your AC system in places like Florida – include provisions to flush the piping. This includes connections from the seacock to the thru-hull, with connectors that are easy to get to and install. plus valves, if you have more than one unit on the boat. You will have to periodically use Barnacle Buster to clean out the pipes, and this is best done in recirc mode with a 5 gallon bucket. Also, think about installing a strainer that will accept a pool-cleaner chlorine tablet (or a sizeable piece of a tablet), to keep the piping clean.

Here, this is really useful comment, many thanks!

I am sorry but this article does not help. You should have tested same type of ac across different brands. But here, you are comparing apples to oranges….

Thank you for this article. Very encouraging in a safe manner.

We have a 1998 Beneteau Oceanis 321. We bought the boat in 2015. The first owner installed a Mermaid M6 6,500 BTU air conditioner shortly after he bought the boat. It has a heat cycle. It is designed to cool 550 cubic feet. We keep the boat on Lake Erie and sail six months a year. It works very well. No major repairs. The only repairs have been that we have had to replace the water pump in 2016 and 2022 due to wear and tear on the impeller.

We use the heat cycle in the spring and the fall. We leave it on most of the time at our dock. It keeps the humidity down in the boat. We have two effective 12v fans that we can run when we are not on shore power. We run it off 15 amp, 115 volt shore power.

I have experience as a yacht broker.

I agree with the advice in your article. I would add the following suggestions, 1. If at all possible buy a sailboat with factory A/C. The installation should be neater and easier to maintain. As the article states, most faults are with the installation. The yard who installed ours did a good job but I have seen many others that are less than seamanlike. 2. If installing an A/C unit, ensure you have an easy way to bleed air out of the water inlet plumbing to the pump. We have to bleed the system every spring after winter haulout. It is a pain in our boat. There are self priming pumps available but they are two to three times more expensive. 3. If installing an A/C unit, ensure you have a relatively easy way to clean the inlet water filter strainer. We have to clean the strainer about once a month in the summer. It is a pain on our boat. 4. If you are installing an A/C unit, ensure you install effective sound proofing. Ours is a bit more noisy than the factory A/C units I have experience with.

We have a Swallow Craft Swift 33 sailboat. It is a very large capacity 33′ boat. After almost a year of exploring options for AC we put in an overhead RV unit in the main cabin overhead hatch. One season in Florida and so far, we are very pleased. The unit is a Houghton B3500. It is low profile with 13,000 BTUs of cooling and 12,000 BTUs of heat. We just could not afford the lazarette space for a built in.
