2023 Award of Excellence

We did it again.

Our client wanted a full enclosure and matching sail cover with rigid solar panels that didn’t interfere with the boom (and vice versa – solar panels don’t like shade). It took a bit of doing, but John created a frame that gets the panels up and over the boom. It uses our own split side mounts to secure the panels, as well as a host of other hardware and fittings. The canvas looks great, the panels work great, the client is pleased as punch. Problem solved.

The build just won an Award of Excellence from the Advanced Textiles Association Marine Fabricator division. It was featured in the March edition of Marine Fabricator magazine. We couldn’t be happier.

Not all solar builds are this complex, but if we can do this, we can get solar on your boat, too. Give us a call.

Celebrating 30 years of excellence

John won his first design award from the  Advanced Textiles Association (ATA) in 1997 and was named a Master Fabric Craftsman by the ATA’s Marine Fabricators Association  in 1999.

Gemini Catamaran Rudder Line Replacement- June 2016

Gemini catamarans, of the 105 series have rudders which can be lifted by pulling on lines.  Lines also pull them back into place and hold them via friction clutch. A frayed line means failure is not long coming.

Frayed equals NOT GOOD

Since Yacht A Fun had already been hauled and blocked for drive leg repair and bottom paint work, maximizing the boat yard stay meant changing the rudder lines.  BUT— that meant dropping the rudders from their pivot tube to access the up-haul knot.

If you followed our Gemini catamaran’s blog back when our steering failed in St. Augustine mooring field, you know that we replaced the steering cables.  To drop the rudders, we had to undo the steering cable’s insertion into the pivot tubes!  Well, at least I knew the needed process.

Dropping the rudders was really pretty easy.  Gravity is a great helper in dropping things.  Diann pushed the pivot tube out of its hull mount while I lifted on the rudder.  Thinking that “jiggling” the thirty pound rudder would aid her effort, I managed to slightly crush the threaded end of the port tube as it edged out of the hull socket.

A new tube is $65 plus shipping.  Thank goodness a hose coupling part for $1.78 was available to insert into the tube and by pounding would round the tube again.  Care had to be taken to not enlarge the roundness.

One seldom enters a boat repair / maintenance item without finding some ancillary aspect which also needs attention.  That too occurred with the line replacement.  The rudder pivot circle which rotates on the hull mounted tube- had worn and lost chips of what appeared to have been a thick application of gelcoat .  The walls of the rudder box had lost some gelcoat- perhaps from oyster shell removal. (Yes, one needs to keep the rudder box clear of growing shell fish!)

Mixing West System epoxy and creating peanut butter consistency filler has become a new craft for Diann and me.  The maintenance was straight forward.

Once the maintenance was completed, bottom paint was added in the same sequence as for the boat bottom.

First coat, of two was Trinidad SR red

The 1” by 2” furring strips served well to create a lifting gantry for pulling the rudders back into place.

Painted with black Petit Trinidad SR & positioned for insertion up the rudder box

By using extra line to create a fish-line to pull the newly attached up and down haul lines into their needed positions, we completed the job.

The story / blog of Yacht A Fun, a Gemini catamaran sailboat, traveling the ICW and east coast with insights to the extended cruising life. Rudder line replacement

Enjoying your blog. Thanks for the tips on rudder removal – it’s on the list. Also in the process of repairing our wood centerboard (1999 M #651, Second Draft). Had some damage from groundings and some from scraping barnacles/wet wood. I’m not great at posting regularly, but if you want to check out our blog please feel free. Facebook.com/SVSecondDraft We are also primarily Florida east coast sailors and are currently in Titusville. Fair winds.

Hello sir, I apologize for disturbing you, but I have a big problem with a 105Mc Gemini rudder, and I’ve seen your website. The rudder on the right is broken in two. (I use a translator) And, I can not find a spare parts store on the Web for Gemini. (It’s very annoying) I am French and my boat is in Martinique. Would you have a store address? It would do me a great service if you do not mind. cordially

Patrice, I am unaware of parts availability for the rudder. Performance Cruising, the builder, is no longer in business. Catalina Yachts is building a greatly revised version of the Gemini. One suggestion is to drop the good rudder and use it as a pattern for custom construction of a replacement for the one that’s broken- if you have lost part of the one broken.

I contacted catamarans.com, which is the company which brokers the current models of the Gemini. They were very responsive to point me on to http://multitechmarine.net/ The service tech there (Alex) was not in. His contact info is [email protected] and phone 954-522-1114

Hope this info does the trick for you…………

Thanks Alex for your explanations. It’s annoying not to have a spare part, knowing that the system of descent and reassembly is broken in two, in the wrong place, just at the corner. I discovered that it was all composite (fibberglass). Not easy for a repair, the connection is small, and in addition there is the hole for the passage of the climbing rope. I am demoralised. Patrice

For those interested? I hade a broken rudder on me 05/105. I live in Florida. Had a new ridder made at Foss Fome (?) in central fL. They now have all the forms made to make a complete rudder. They should be able to make with a phone call.

Hope that help.

Cattitude Jon 757 717-6699

Thanks for the input. Sorry for the long delay in response.

My best suggestion is to follow the lines themselves and use them to “fish” the new ones thru.

Arguably one of the United States most popular cruising catamarans, Gemini Catamarans offer a range of domestic-built sailing and motor cruising vessels. Designed for affordability, compact design, ease of use without compromising on comfort and liveability.

The Gemini models deliver an almost unbeatable level of accommodation in relation to their size, with far more private cabin space, specious heads, and elegant dining/living space roomy enough to entertain in.

The Gemini range is a versatile craft to suit a wide customer base from serious liveaboard sailors to coastal weekend cruisers.

History of Gemini Design

The original Gemini hull shape and design was patterned in 1969 by Ken Shaw, with the Gemini 31. Over the years that followed there were serval variations to the original design in the LOA and styling but the Gemini image largely remained the same with both the Gemini 3000 and the Gemini 3200 model.

It was in 1996 when Tony Smith took ownership of the design under his company, Performance Cruising, that he redesigned the hull shape and introduced the much-loved Gemini 105 design.

For over 17 years Tony Smith retained the classic design of the Gemini 105 model, splashing over 1200 hulls from humble beginnings at his facility in Annapolis, Maryland.

At thirty-three feet long and with a beam of just fourteen feet the Gemini 105 was large enough to liveaboard but great value for money whilst also having the flexibility with retractable daggerboards for upwind sailing and gunkholing in the shallows, and due to its compact size, could snuggly fit within a conventional boat slip.

It ticked all the boxes for so many Americans looking for an entry-level catamaran without compromising on comfort.

Flowing a partnership with Hunter Marine and a generous buyout from The Catamaran Company, Gemini was able to live on under the direction of the Smith’s daughter Laura Smith Hershfeld who is now building variations of the classic 105.

We see the Legacy 35 sailing vessel as a fresh take on the proven favourite as well as Gemini’s very own power catamaran range with the Freestyle 339 and customizable Freestyle 37 model.

Gemini Models

Gemini 105mc.

The original and the classic Gemini 105-sailing design was originally conceptualised in 1996 and only later changed to the 105MC in 2004 with some notable differences being the extended cockpit cover to allow a full enclosure and a slightly taller mast.

It was in 2011 that Gemini offered the limited-edition design Touch Models whose upgrades included cherry veneer finishes, Corian countertops and ducted air conditioning.

Since its inception, the 105 model remains one of the most popular sailing catamarans, with a proven and much-loved design. Expect spacious accommodation, in relation to its size, with a light and airy saloon and cockpit, a 3-cabin layout and a large wet head.

The c-shaped settee in the saloon converts into an additional large bed for extra guests and with a propane-powered fridge offering ample food storage, this small vessel provides an excellent platform to entertain and host all your friends.

Built for safety rather than speed the Gemini 105 won’t break any records but still can achieve 40-50% of wind speed and the ability to point at about 50 degrees (apparent) to wind. Utilising the centerboards and sailplane contribute to its ability to sail closer to wind than most production catamarans out there.

And given the centerboards are lifting and the rudders are a kick-up design you can sail through as little as 2’ of water. Fitted with either outboards or Westerbeke 30b3 diesel engines, both options are fitted with great accessibility for servicing and maintenance.

The 105 design is no longer in production and has been replaced with the new Gemini Legacy 35, but there is still a large number of pre-owned Gemini 105 on the used boating market around the world.

Specifications

*Specifications provided from:

https://www.geminicatamarans.com/Gemini-Models/Gemini105Mc-Specifications.html

Designer Tony Smith suggests that this model is the ideal ‘couple’s catamaran’, perfect for those new to the boating world or a coastal cruiser on a monohull budget.

This was the design that has built the Gemini brand name into one of America’s most popular domestic-built catamarans.

For those in the market for pre-owned vessels, this model is well worth considering, especially since it still fosters an active and supportive owner’s association as well as a local builder who is willing to provide support to all Gemini owners.

Gemini Legacy 35

Based on the original Gemini 105 design, the Legacy 35 takes a fresh look at a proven family-friendly performance cruising catamaran.

Still retaining a 34-inch draft, allowing for shallow water anchoring, a 14-foot beam for easy haul out and compact size only 2 feet longer than original the flexibility that this vessel offers is admirable.

It is argued that this 35 model offers more interior than most 40 foot monohulls, still offering the iconic Gemini design down below. The large C-shaped lounge area in the saloon with a table facing aft, a spacious galley amidships on the starboard hull, with cabins and double berths fore and aft.

The port side accommodates the owner’s stateroom with an aft head, a navigation station amidships and a spacious cabin forward for the mast, there really is plenty of room for the whole family below the decks here.

Similar to that of the Gemini 105 the Legacy 35 handles easily, tracking straight with its shallow keels and together with a square-top mainsail and optional Selden sprit you can enjoy speedy sailing atop this stable platform, with virtually no heeling.

This design has also included an upgrade to the engine specs to include two 15 horsepower shaft drive Yanmar diesels, allowing for a much higher and efficient motoring speed.

*Specifications and features provided from:

https://www.geminicatamarans.com/Gemini-Models/GeminiLegacy35-Specifications.html

There is no doubt Gemini’s new Legacy 35 model has been well received by the wider American sailing customer base, receiving raving reviews from its cruising community. Gemini still retains its place in the market based on its core values of comfort, sailing ability and excellent value with this popular new sailing design.

Gemini Freestyle 37

The Gemini Freestyle 37 is a completely new concept for Gemini and also in boat design, fully customizable for a world where flexibility is key.

Each Freestyle model can be tailored to suit a variety of sailing ambitions, whether it be as a basic sailing family catamaran, a day charter boat or even luxury cruising vessel complete with chaise lounge, outdoor galley and wraparound bar.

Still based on the classic Gemini 105 hulls this vessel can be purchased at a very low base price and customised to suit any family. The basic base price offers a similar style to an open picnic-style boat with deck furniture available as modular or built-in sections from the factory, either at initial purchase or as a retrofit.

There is also an option for a full-size hardtop canopy that can be used as a sun deck or platform for solar panels. The added platform for solar allows for a new ‘green’ version of the design, developed to include electric engines and ample solar power for appliances.

The Gemini Freestyle 37 not only offers the trusted design features of the original Gemini hulls but opens up the possibilities to a far wider audience of sailors with its flexibility in custom-built versions.

Gemini Freestyle 399 Power

Taking the streamlined design features that step further, Gemini now has their very first ultimate day-powerboat catamaran. Taking all the innovations of customizability from the Freestyle 37 and evolving this to suit the motorboat market.

Unlike the other models, this design incorporates a centre consul design powdered by twin Suzuki DF90A outboards with a cruising speed of 15 knots and 22.5 knots at full throttle. This helm station is positioned front and centre makes the cockpit an ever-larger entertaining space.

Similar to the Freestyle 37 this model is fully customizable to suit almost any purpose with basic day use versions, charter and full luxury fit-out options available.

This design takes everything great from the earlier sailing models to put a new spin on the motor cruising catamaran, offering the same affordability, comfort and cruising capability that Gemini is so well known for.

Frequently Asked Questions

Answer : Gemini Catamarans are manufactured at the Hunter Marine plant in Florida.

Answer : The Gemini is designed as a coastal cruiser and therefore are designed for a different purpose. It has been reported that some owners of the sailing models have crossed open ocean passages such as the Atlantic and Pacific oceans.

Answer : The Gemini range is a moderately priced modestly constructed catamaran. Their standout features include excellent value, outstanding accommodations and solid sailing performance. There is an active and supportive owners’ association as well informative support from the local US-based build facility. Highlights include: Narrow beam offering ease when hauling out. These vessels fit into a standard slip, lowering the cost of ownership and reducing haul-out fees. Shallow draft combined with kick-up centerboards and rudders as well as outboards that can raise up. This allows the vessel to be anchored in as little as 2’ of water. Great sense of liveability . Despite its size, Gemini catamarans offer larger living spaces than most other comparable-sized boats on the market, combined with a minimum of 6’ of headroom inside and up to 6’7 of headroom in the cockpit. Better than average speed. With regards to their sailing vessel’s range they won’t necessarily bet speed records but for a vessel of her size achieves a noteworthy 40-50% of wind speed and the ability to point at about 50 degrees (apparent) to the wind. Outstanding engine accessibility . Careful consideration has been made with all models for access in and around the engine wells, for both the diesel and outboard fit-outs making it far easier to complete maintenance and servicing.

Gemini 31/3000

Long america's only production cruising multihull, this boat has many fans..

Tony Smith sure knows how to make the most of a good thing. The British multihull lover has gotten more mileage out of one design than any boatbuilder we know. And why not? With more than 200 Geminis built to date, and interest building, why switch?

In 1972 Smith designed and developed the 26-foot folding trimaran Telstar in England. He brought the molds to the U.S. and built 350 of them before a devestating fire destroyed the molds in 1981. Desperate to resurrect his business, he grabbed some old catamaran molds he had—the Aristocat—changed the name and that same year launched the first Gemini 31.

Three years and 27 boats later, he retooled to produce the Gemini 3000, which is essentially the same boat, but longer. Today, yet another incarnation of that first design—the Gemini 3200—continues to sell well.

Several years ago, Smith planned to introduce a larger 37-foot version, but the cost was much higher and despite building one boat, he changed his mind. The multihull business in this country has been slow to take off. And as even the established monohull builders like Pearson and C & C have found out, there ain’t much room for error. Instead, Smith has refined the Gemini much like the Volkswagen Beetle. By listening to owners’ comments, and by incorporating his own evolving ideas, the boat has changed a good deal, though one would be hard pressed to distinguish, at a glance, between a 1984 Gemini and a 1992 model.

The funny thing about the Gemini is that it’s an old design. Ken Shaw drew the lines in 1969. There’s nothing particularly contemporary about it. However, by painting the cabin sides black (Euro styling), adding a swept-back fiberglass “pilothouse” and gradually adding length to the full-bodied hulls, the Gemini has always looked like she belonged with her contemporaries, whether that was the 1980s or 1990s.

The most important thing to remember when evaluating this design is that the Gemini is essentially used as a 30-foot live-aboard, cruising catamaran. While faster than most monohulls of equal length, it has no pretense of being a racer. How could it be with such a spacious interior? Further, many of Smith’s customers are older folks who are tired of heeling, don’t have $200,000 to spend, and don’t plan to circumnavigate. In fact, most Geminis we’ve seen are happily puttering up and down the Intracoastal Waterway along the Eastern Seaboard and Gulf Coast. It’s perfect for that.

Summing up the design gets a little dicey when offshore work is discussed. The Gemini’s liabilities here are several. Because of the substantial accommodations built on the bridge, which necessitates lowering it for headroom, and the solid bridge forward (as opposed to netting), it’s a bit heavy. Smith says that if loaded for extended cruising, there is not a lot of clearance between the bottom of the bridge and the surface of the water, and it will pound going to weather in choppy seas. Sailed light, the Gemini will do quite nicely and be much more comfortable.

The performance of full bridgedeck cats, such as the Gemini, also suffer a bit from the extra weight and windage. Smith, a racer at heart, admits that if he had his druthers he’d build an open bridge forward, but for his cruising clientele, the full bridge makes more sense.

Nevertheless, Geminis have, according to Smith, crossed the Atlantic, cruised the South Pacific and Caribbean.

Having spent a week cruising the Chesapeake Bay aboard a Gemini 31, we found the boat extremely comfortable and fun to sail. With a large queen-size stateroom forward and double staterooms aft in each hull, there’s room for Mom and Dad, Junior and Sis, each in their own private cabins.

Speed reaching and sailing upwind was about 50 percent faster than what we could do in our 33-foot Pearson Vanguard. We hit double digits just once. But sailing in moderate winds we’d make eight and nine knots when our Pearson would do five and six. Three or four knots may not seem like a lot, but for sailboats on an all-day passage, the difference cuts hours off sailing time.

Best of all, it’s level sailing. This makes for very restful cruising.

Punching to windward in a chop, we did buck a bit, and the quicker motion of a multi takes some getting used to. All in all, we came away impressed with its space and performance.

Construction

The key to high-performance multihull construction is lightness and strength. The rapid evolution of composite building techniques now makes possible the use of lightweight core materials, specialized fibers such as Kevlar, and strong resins that in combination yield a panel that is much lighter and stiffer than solid fiberglass or fiberglass with just “traditional” core materials such as end-grain balsa and PVC foam. Vacuum bagging helps assure uniform bonding of all the “parts.” Naturally, such construction is costly.

Construction of the Gemini, which is marketed as a comfortable, low-priced cruising catamaran rather than a spartan high-tech racing machine, is quite conventional. The hull is built of solid fiberglass—mat and woven roving. The deck is cored with balsa for stiffness. The new Gemini 3200 incorporates a layer of vinylester resin as a blister barrier. Twenty percent of the owners of older models responding to our survey reported “some” blistering—a below average incidence.

The centerboard trunks were laid up separately in the early boats, but Smith said it was difficult getting good tolerances for the centerboards to fit right. Now the trunks are part of the hull mold and the slot is a guaranteed two inches and the polyurethane-coated plywood centerboards 1-7/8″.

Obviously, to keep weight light, a multihull builder isn’t going to use any unnecessary laminations. Consequently, many multihulls feel flimsy compared to monohulls. One Gemini owner said, “The strength is a little lower than I would have liked, but it helps hold the cost down.” And, we might, add, the weight that is so important to multihull performance. The rock steady feel of thick decks is somewhat at odds with the requirements of multihull design and construction.

A frequent complaint of Gemini owners is gelcoat flaws. “Gelcoat has many voids,” wrote one owner. “Some gelcoat yellowing and crazing,” said another. The interior woodwork is acceptable to some owners, and not to others. “Woodwork finish is inept,” said one owner. “Finish work is my biggest complaint,” said the owner of a 1985 model.

Smith admits that leaky windows were a problem in early boats. The design has since been changed, including the use of Lexan in place of Plexiglas, and a new system to bed the large panels allows for thicker beads of sealant to absorb the expansion and contraction of the windows.

Most owners, however, seemed to feel that these are minor problems they’re willing to live with. They rate construction lower than other attributes of the boat, but overall still are satisfied with their choice of the Gemini. We’d like to see a bit more glass in the Gemini, or the use of a core for stiffness and strength, though we acknowledge it would increase the price.

Performance

Besides accomodation space and low heel angles, speed is a major factor in choosing a multihull. Only one owner expressed disappointment in his Gemini’s maximum speed attainable. True, it won’t hit those 15- to 20-knot speeds possible in more performance-oriented cats and tris. Nearly all owners, however, remarked on the Gemini’s good light-air performance. And, as we found during our week’s cruise of the Chesapeake Bay, the boat is definitely faster than a cruising monohull of equivalent size.

A key to performance in any multihull is keeping weight down. Unfortunately, many owners overload their boats and this has a direct effect on speed and pointing ability. It’s a problem with no easy answers for live-aboards and long-term cruisers: Either buy a boat with longer hulls and hence greater payload capacity, or live with sub-par performance.

A significant feature of the Gemini is its centerboards, which improve pointing and tacking considerably. Many production catamarans today have fin keels on each hull. The thought here is that the problems inherent with centerboards (broken pennants, jammed boards in the trunk) are eliminated, while acceptable upwind sailing characteristics are retained. This may be true, but there seems no denying that centerboards improve overall performance. Further, the fins add to wetted surface, which increases drag and adversely affect maneuverability.

It is interesting that author Bernard Perret wrote in the October 1990 issue of Cruising World regarding his search for a cruising cat: “We focused in on exactly what we wanted: two sideboards to help us tack more efficiently against the wind and to maintain a shallow draft…”

Having ourselves sailed on production cats without centerboards that were dogs to windward (close reaching was virtually impossible, leaving motorsailing the only option), we consider daggerboards or centerboards an important criteria in selecting a catamaran. Perret said he tacks his French-built 36-foot Naviplane through 115 degrees true, but that’s nothing to write home about. We’re sure he could do better if he wasn’t loaded down with cruising gear for five. Under optimal conditions, Smith says the Gemini can tack through 80 degrees. Burdened with bicycles, computers, three anchors, a library, and food for six months, that number is sure to increase.

A number of owners noted the boat’s lack of directional stability (because there’s not a lot of boat underwater). But they also acknowledged that it is very easy to steer, and that with the lee board down, it balances nicely.

The wide sheeting angle of the early boats made the genoa inefficient upwind. Smith says this has been improved, by means of lengthening the track, in the Gemini 3200.

Under power, the Gemini performs well. The outboard turns with the rudders for assistance in close quarters—most multihulls need it. And it retracts for sailing. The arrangement has been modified several times over the years.

The current Gemini 3200 comes equipped with a 40-hp. Tohatsu. Some 31 owners felt more power was needed. The results of our recent Reader Survey didn’t rate Tohatsus very highly, but Smith says a 25-inch shaft is very important for maximum performance.

The Mercury 35, standard on Gemini 31s and 3000s, is no longer made. The Tohatsu, he said, is the only engine in that power range available with a 25-inch shaft. In any case, motoring the Gemini at decent speeds, and in comfort, is certainly possible, though punching into head seas isn’t its cup of tea—multis are too light and their motors often too weak to grind out the miles like a heavy, diesel-powered monohull.

Twin Yanmar and Volvo diesels were available, but at such an increase in cost, few buyers would consider them. We’d take the outboard for cost savings, clean interiors, and ease of repair and maintenance. So what if it’s a little noisier? You’ll motor less with a catamaran than your old monohull anyway.

Accommodations

There are numerous appeals to the cruising cat—the large foredeck, large cockpit and the possibility of three or more private sleeping cabins. The Gemini has all three.

The full bridge means there is no netting between the hulls as seen on many cats. This adds weight, but does help deflect waves. From a particularly hedonistic point of view, the netting is best for lying on face down, watching the water fly by. On the other hand, footing is precarious. The full bridge makes anchor handling easier and provides for possibly a little extra stowage space.

The Gemini’s cockpit is large enough to walk around in, with good footing and stowage. Bulkhead wheel steering is convenient whether standing under the so-called pilothouse (added after hull #10), or sitting either on the bench seat or coaming top.

There is not standing headroom in the saloon forward of the 6′ 2″ pilothouse, but this isn’t a major item. Several interior plans have been offered over the years. The one we chartered had a 64″ x 75″ double berth forward in the starboard sector. The view from the bunk looking through the forward windows is stunning! The head with shower was in the port bow and aft, in each hull, was a quarter cabin. The 48″ x 75″ bunks in these weren’t quite as wide as a couple might like, but tolerable, and certainly more than big enough for kids. The nav station was amidships to port and the galley in the starboard hull, with 6′ 3″ headroom. Headroom forward is 6′ 0″ .

An interesting dilemma of outboard-powered boats is the question of generating power for live-aboard conveniences. Outboard engines aren’t able to generate the amps necessary to run a lot of hungry electrical appliances. To combat the problem, Smith has elected to use RV-type propane/12-volt/110-volt refrigerators. These are well suited to multihulls because they work most efficiently when level. LPG, of course, will be the usual energy source for these units, though at the dock shorepower works well. We sailed with a Dometic three-way refrigerator for several years and found them too poorly insulated for 12-volt service.

An instantaneous gas-fired water heater services the Gemini’s shower, which again eliminates the need for electricity.

About the only appliances that must then be accounted for are cabin lights, fans, stereo and pumps. This can be handled by several good quality batteries, though some owners note the need for alternate energy sources. Solar panels, in our experience, can help a great deal, but several fairly large ones will be needed. They are difficult to place where shadows won’t limit performance, and where they aren’t likely to be stepped on. Plus, their life expectancy is depressingly brief—several years in our experience. A better bet, for many cruisers, will be a pole-mounted wind generator capable of producing, say, six to seven amps in 15 to 18 knots of wind.

The Gemini 31 is a comfortable coastal cruiser that benefits from its builder’s undying devotion. The quality of workmanship isn’t what you’ll find in more expensive monohulls or multihulls, but this is also one of the few cruising multihulls that’s affordable to buyers in the $50,000 to $80,000 range—used or new.

Brand: Gemini 105

Jump to Gemini 105 Catamarans For Sale

The Gemini 105 was designed to be affordable, compact, relatively easy vessels for sailors new to catamarans. Production began with the 105M (meaning 10.5 meters), with a design change in 2004 to the 105MC, notable differences being the extended cockpit cover to allow for a full enclosure and a slightly taller mast (while still remaining ICW-friendly). In fact, the “c” in the 105Mc stands for “convertible,” likening the cockpit to that of a sports car. The Gemini Owners Group has a complete list of the numerous small differences between the M and MC as well as there are owner interviews below on this website that explain differences.

Gemini 105M (Florida)

Aireze is a Florida-based 1999 Gemini 105M catamaran for sale by owner.  The Gemini 105 was designed to be affordable, compact, relatively easy vessels for sailors new to catamarans.  It is one of the most popular catamaran designs ever built with over 1,200 hulls constructed.

Aireze is easy to handle and well equipped with a new Raymarine Autopilot, Lewmar electric windlass, new electric head, lazy jacks, 2-100 watt solar panels, new Garmin 9″ touch screen, davits , all new rigging and lines installed 2016, new water heater, new alternator, water pump, impeller, elbow, sea strainer, heat exchanger just serviced,  new belts and filters. …

Gemini 105M (California)

First introduced on the original Gemini 105M, the hull shape of the 105M is still revolutionary in the multihull industry. The hulls of the Gemini 105M are shallow and shaped much like a “teardrop” which requires little force to move the 105M through the water yet it also provides a high load carrying capacity.

Gemini 105 Review

No catamaran discussion would be complete without a nod to the 34’ Gemini 105M and 105 MC line of catamarans, created by designer Tony Smith. From modest beginnings in 1996, the Gemini 105 has become one of the most popular domestic-built catamarans in the United States, with over 1200 hulls splashed.

making boat life better

Our Gemini Catamaran

Published on May 18, 2015 ; last updated on June 20, 2020 by Carolyn Shearlock

We’ve had a number of questions on how we like our Gemini catamaran or how was it to go from our previous boat — a monohull Tayana 37 — to it. Here’s our listing of the pros and cons.

In a nutshell, we LOVE our Gemini catamaran for what we are now doing — two people living aboard full-time, coastal cruising in the Florida Keys and going to the Bahamas for several months at a time. But I’m not going to say it’s the perfect boat for everyone.

Okay, with that out of the way, there are a few things that we need to say:

• The Tayana 37 is a true blue water boat. The Gemini is a coastal cruiser. They are very, very different boats and designed for different purposes.
• Because of that, it’s almost impossible to truly compare them.

When we bought the Tayana ( Que Tal ), we didn’t know if we’d cross the Pacific, but thought we might (we didn’t). We wanted a boat that left the possibility open. The Tayana did well for us in the Sea of Cortez and down the coast to El Salvador, but the reality is that the Gemini would have been great, too. Probably better.

Things that we particularly like about the Gemini ( Barefoot Gal is a 105M):

• The living arrangement. It’s just a good layout for us, with a large “living room” (settee and table). The whole boat is much lighter and brighter, too. We also like the fact that the cockpit opens right into the living area, without going up and down stairs all the time. It’s also easier to get into and out of the queen berth (side entry) as opposed to the V-berth on the Tayana.
• Huge cockpit. It’s great for entertaining or even just the two of us, with room to actually walk around. The Tayana 37 has what’s referred to as an “offshore” cockpit, meaning it’s very small so that if a wave breaks into the cockpit it won’t sink the boat. But that means that it’s a very tight fit for four people. The Gemini is a much better layout for having people over. When we bought Que Tal , we underestimated how much we’d use the cockpit for things other than just steering the boat.
• Maneuverability. The Gemini is so much easier to handle in close quarters, it’s not even funny. The drive leg makes it like having an outboard, in that you steer it as well as the rudders. The Gemini is also technically 3 feet shorter than the Tayana (34 feet vs. 37) but with the Tayana’s bowsprit, it’s more like 8 or 9 feet shorter in reality. The lighter weight of the Gemini also makes it much more responsive. And any full keel boat such as the Tayana, in the words of another Tayana owner, “backs like a drunken elephant.” In other words, you don’t have a clue where it will go. Less freeboard on the Gemini also makes it easier to pick up a mooring ball both as it’s easier for the person at the helm to see it and much easier for the person at the bow to pick it up. The stress level on the Gemini as we approach a fixed object (dock, bridge, lock or even a mooring ball) is so much less than on the Tayana. The ease of getting underway/returning resulted in us going for a lot of short (1 – 2 hour) daysails. We had no idea how much this one factor would contribute to our enjoyment of the boat — and we’ve both always loved boating!
• Ease of sail handling. The Gemini’s sails are considerably smaller than the Tayana’s and the boom is much lower to the coach house roof. It is so much easier to raise/roll out the sails and stow them again, and the spinnaker is also a much more manageable size and has a larger wind range. We never wonder if it’s worth the effort to set the sails, even for a short trip. We’re not getting any younger, either (Dave is 77 and I’m 55): easier sail handling and a smaller anchor mean we’ll be able to cruise longer.
• Speed. Despite being smaller, the Gemini is considerably faster under sail and power. Our one-day range is considerably expanded. We can sail a lot more both as we move at a reasonable speed even in light winds (the drive leg pivots up out of the water easily to decrease drag) and we can afford several hours of light-air sailing and still make our intended anchorage since we typically motor at 6 knots versus 4.5 knots on the Tayana. Believe it or not, the Gemini sails slightly closer to the wind than our Tayana.
• Shallow draft. Draft was never a big issue in the Sea of Cortez or along the coast of Mexico and Central America. But it is in Florida and the Bahamas. Our Tayana theoretically drew 6 feet but loaded for cruising it was probably closer to 6½ feet. The Gemini draws about 2½ feet with the centerboards up but the drive leg and rudders down. We can go lots of places that many other boats, including a lot of catamarans, can’t. And we like to explore off the beaten path. A related factor is that our bridge clearance is just 45 feet, also giving us the freedom to go places some others can’t . . . and we have a lot less stress going under those 54 and 55 foot spans!

Bottom line is that for what we’re doing , the Gemini catamaran is just plain a fun boat. But I want to emphasize the “for what we’re doing.” Should we decide that we want to go to the Virgin Islands, we won’t have the option of going offshore — we’ll have to island hop down (yes, I know a few Geminis have gone offshore but I’ve also read their accounts).

To keep the speed and maneuverability that we like, we have to watch how much we load on board — and that means that we can’t carry as many provisions. The guest arrangements are great if one person comes, bad for more (what’s billed as a double berth is 4″ narrower than a double bed). The galley arrangement isn’t quite as good, but it’s not at all unworkable. Finally, the motion of a catamaran is different than a monohull. Not necessarily bad but it does take some getting used to if sailing in chop.

The holding tank is small at 18 gallons. After a year of cruising, we switched to a composting head ( read more about our reasons here ).

Our Gemini is an “M,” built in 1999 towards the end of the “M” series and has many features of an “MC” such as composite centerboards instead of plywood. The MC has many features that we’d like but the available ones at the time of our purchase were out of our budget.

The current model is the “Legacy” and it is totally redesigned with the interior layout changed slightly and, most importantly to us, skegs instead of centerboards. While the skegs are lower maintenance and require no effort while underway (versus having the lower a centerboard if sailing above a beam reach), we like the improved windward performance that the centerboards bring over a skeg.

Everything is a tradeoff. We are extremely glad that we decided on a Gemini as we absolutely love it. Some of the things that we love about it — such as the speed — are fairly typical of catamarans as opposed to monohulls, while other items are more specific to having a small catamaran or even to the Gemini (maneuverability).

I’ve been asked a few times if we intend to get a larger boat now that we’re going to be living aboard full time. You’ve probably already guessed that our answer is no — the Gemini catamaran is big enough for our needs and its small size leads to many of the things that we like about her. Within reason, smaller is just easier . . . and costs less too!

Some of the differences we expected, such as the living arrangement and the large cockpit. But we didn’t realize how much easier she’d be to “move” — whether by motor or sail. And that’s turned out to be a big part of why we love her!

May 18, 2015 at 1:00 pm

I have only ever sailed monohulls. I am looking to live aboard in the next few years. I was considering a boat like your former one for the same reasons – like leaving the possibility of ocean crossing open. Still open to all possibilities, which is why your post gave me a lot to consider. Thanks again.

How much of a factor were tramps when you picked the Gemini? I love everything about it, except for I have this dream of laying out on the trampolines, and I’m not sure I can give it up. How much do you think you’d use them if you had them?

We’ve been on some cats with tramps (friends’ boats) and didn’t use them as much as we’d envisioned. So we didn’t really consider them (or the lack of them) in picking the Gemini. I don’t think (I may be mis-remembering) I’ve seen any of the small cats with them — they just need the space for living quarters and storage. Probably the biggest thing is that since it’s solid up from, there is more wave slap when you’re beating. We don’t find it too annoying, but some people hate it.

Bob Kimble says

March 25, 2016 at 8:13 am

I too had wanted tramps when I bought my Gem, but the hard foredeck turned out to be a blessing in disguise. It was the perfect place for morning sun salutes.

Rik Dove says

May 18, 2015 at 9:10 pm

True. And I agree with the thought. Problem is… Dikenga and I have been through so much. She is family. I could never bring myself to sell my Tayana

May 19, 2015 at 7:57 am

Sounds like a perfect boat for the Keys. We had a 30′ Iroquois for 14 years with a trampoline and while the kids loved it, it made the boat wetter going into heavy seas. I’m thinking too, now that I’m older, it wouldn’t be as stable a platform for foredeck work. We moved up to an Island Packet catamaran 8 years ago with a solid foredeck. It’s very dry( has a pod to break waves) but there is slap at anchor if there’s a heavy chop( no fun on any boat, either). What’s nice about the Gemini and Island Packet is they usually fit into a conventional slip, being 14 and 15 foot beam, respectively. The cockpit is another “room” for us. Thanks for your thoughts on your model. We sailed a Legacy last summer as a demo, but could never afford a newer one.

I looked at the Gem’s and ruled them out for several reasons. I did find 2 of the IpY Packet Cat 35’s for sale and a friend and I each bought one of them. I’m getting ready to head off this year, circumnavigation and would love to connect with you. Perhaps Carolyn can assist us if you’re interested.

I emailed re the name of a product you’d recommended and I couldn’t remember. You got back to me in a day! I was very surprised and happy. Thank you so much.

May 19, 2015 at 8:56 am

What a good comparison! We’ve been living aboard our Cal 39 in the Leewards since November 2014, and I have enjoyed the luxury of space and light when I visited friends with large catamarans. It didn’t occur to me that we could find a catamaran with maneuverability and a size that would be comfortable for gunk holing in the Chesapeake and the Florida Bay. My husband got very excited by your article. You’ve planted a seed for our next stage of cruising a few years down the road.

Tim Sheahan says

May 19, 2015 at 2:16 pm

Do you have problems with stress cracks,..a friend has one and has cracks along all his shrouds and basically all around the deck, everywhere anything is bolted thru.

May 19, 2015 at 6:43 pm

The gelcoat is a problem area on the Gems. Ours is chalky and has a lot of crazing. The company swears that it’s not structural and that is how it seems on all that we’ve seen and owners we’ve talked to — not pretty but not structural.

May 19, 2015 at 7:58 pm

Right, we’re doing his this fall, just curious if it was universal.

After owning our Gemini 105M for 15 years, we are putting it up for sale. It has been a great boat to own and we have had many great trips with it. We will miss it and all the great Gemini sailors that we have met over the past 15 years.

Happy/sad time.

I have been hearing about the gemini so much that for the last year I have been researching every thing about this cat and the more I read the more I am looking forward to purchasing my own. I’m in love with it and have not even chartered one yet.

December 1, 2015 at 11:30 am

We bought our Gemini 105M from PCI in 2000. It’s been a great boat and we have had 16 years of great sailing. Health issues and age are catching up with us so we are putting our boat up for sale. We are spending this winter in Cocoa Village, FL.

December 1, 2015 at 3:53 pm

Glad to hear of your many fun years aboard! It must be a tough decision to sell her . . .

Did you end up selling it ? Looking for a 105M Joe

December 15, 2015 at 9:41 pm

I’m looking at getting a Gemini legacy 35 for a live aboard and possibly some blue water sailing. What would be the pros and cons of this type of sailing occasionally. I have 2 children that will with me so accommodations should be just right.

March 24, 2016 at 6:14 pm

Those of you who are considering a Gemini:

Have a look at the Canadian-made “Tomcat.” We looked at one at Miami Boat Show and were very impressed. Very like the Gems, yet to us, better thought out. If we were in the Gem market we’d seriously consider them.

March 24, 2016 at 6:39 pm

We saw them 2 years ago and were also impressed. However there are almost none available used, and the backlog for new ones is several years long. Or at least it was then.

Michael McIntosh says

How many degrees off the wind will she sail?

March 25, 2016 at 12:00 pm

50-ish, depending on sea state. Smooth water, closer than that.

June 9, 2016 at 9:48 am

hi great comments evaluating your cat. The small cats do it for me too, I now have a Catalac 10m after my first cat a Wharram Tiki 30! The centerboard set up ibdeed better upwind sailing but so much weaker in gunkholing! It is amazing how these under 35 foot cats have such large living areas. I would not howecer use a Gemini where I am cruising with my Catalac because no chandlers, no technical backup. My Catalac can take quite a knock which leseer strong cars wpuldnt survive. Imagine hitting an old bridge head thats completely dubmerged and nowhere indicated on charts but in major river gere in Mozambique. Great blog keep it up, I admire those bloggers that entertain/inform us so well.

Dan Rupli says

June 17, 2016 at 5:03 pm

I love the whole idea of the Gemini 35, but will always want to go around the world at least one time. Is there no compromise between catamaran comfort and Tayana blue water capabilities?

June 17, 2016 at 7:51 pm

There are definitely boats that are in between . . . some of the 40-foot cats and some of the lighter monohulls. No boat can be everything, though, so you have to decide what’s important for you.

June 20, 2016 at 1:42 pm

Thanks for this insightful article. I am one of many investigating/considering the Gemini – I’m curious whether you found yourself sitting on the combing when handling the wheel? I had not realized the other advantages you pointed out regarding visibility/convenience in handling.

June 20, 2016 at 3:34 pm

We rarely hand steer — only when doing close quarters work. The rest of the time we let the autopilot do it’s thing. But yes, we usually sit up on the “upper level” on the side of the cockpit.

mikeoore says

August 14, 2016 at 9:53 am

Great article. We are close to a boat purchase and liked both the gemini cats and my lifelong favorite, the Tayana 37. Being so different, and generally for different purposes, it was hard to make a choice. Your story helprf. Thanks

August 14, 2016 at 10:17 am

We really like both, but they are very different boats and best suited for different types of cruising. Glad you found the comparison useful!

Brian Kepner says

Paul English says

July 21, 2017 at 9:13 pm

I’m still struggling with the whole “blue water” distinction – and I realize it is not necessarily razor sharp.

What features did your mono have that made it blue water, that the Gemini doesn’t?

Does the Gemini itself preclude blue water from your perspective – like you wouldn’t consider an Atlantic or Pacific crossing with it? Or would you consider it with (presumably pretty expensive) modifications?

And a more general question – do you think you would have been ultimately “equally open” to blue water sailing by purchasing a non-blue-water boat to start with, then simply traded up when you were ready and certain that you were going to cross an ocean?

July 22, 2017 at 7:11 am

It has a lot to do with build strength. The Tayana has a much thicker and heavier hull that would be much harder to hole. The deck to hull joint is also much “beefier.” Chainplates are attached with more bolts and are themselves larger. Winches were oversized. Water and diesel tanks were much larger. It’s also a heavy displacement boat and comfortable (well, relatively!) in large seas. It’s also things like the size of cleats, having secure places to clip in on deck and a protected cockpit.

I know of one Gemini that circumnavigated (Slap-Dash) and while they beefed it up before they went, they did major repair in most of the big cities they hit along the way.

The designer of the Gemini took one across the Atlantic — again, with modifications.

The thing about crossing an ocean is that you don’t know what weather you’ll encounter and your boat has to be okay to handle large seas. Now, we could island-hop through the Caribbean, where we’d have numerous open water passages — but most just about 100 miles long. That’s a single day. You can get a pretty good weather forecast for the next 24 hours so even “unexpected” conditions aren’t going to have the huge seas that would be a problem.

So, while others may have crossed oceans in a Gemini, I wouldn’t.

As to your more general question. I think when we began cruising (2002), there weren’t the blogs and Facebook that showed people cruising on a smaller scale. Most information came from circumnavigators — or at least ocean-crossers — in books and Cruising World. So our initial thoughts were that we’d be like all those folks . . . and wanted that type of boat.

Totally agree! We love our Gem too!

Steve Barnes says

July 22, 2017 at 4:01 am

What’s your hull number? We are a 1999 M #651 and have wooden boards. In good shape now, but was a pain restoring them after barnacles got through the paint and water rotted several spots.

July 22, 2017 at 10:34 am

We’re 655, just 4 after you.

Thomas Pierquet says

September 18, 2018 at 11:03 pm

I am wondering what the boat speed is cruising at 2000,2500,and 2800 rpm respectively. I heard someone claim 8kts at 2800rpm. Is this possible? Or is that a stretch? I presently have a Beneteau 311 (cruises at 6kts@2800rpm) and have been considering a Gemini 105MC for more room. My wife would like to have a bigger cabin and more boat speed on the way home if no wind.. Also, how valuable is the option of the Screecher sail to the performance of these boats?

September 19, 2018 at 8:45 am

I’d say that’s a stretch. We can motor a little over 6 knots in very smooth water. Looking back on our logs, 5.8 is more common at 2800 — but remember that we are loaded for cruising/full-time living aboard, probably much more so than you would be if you still have a land-based home. We don’t have a screecher, so I can’t answer that — I know it would be fun on certain points of sail, but can’t talk to how it actually performs. I think we’d use it on the furler more than we use our asymmetrical spinnaker.

September 19, 2018 at 9:18 am

Thank you for your very timely reply. It’s always good to hear from an owner to get accurate information. I have been reading everything I can about the Gemini. I have decided that I want a 105mc to get the latest version with the centerboards. I would welcome all and any comments directly from owners of any of the performance positive or negatives. I enjoy my Beneteau 311 but need a main cabin bed with more room and more space for my grandkids to come along. Thanks again

October 2, 2018 at 1:14 pm

Great review of the boat. We are also considering a Gemini 105M along with a Prout Snowgoose. Can you comment on wave slap when at anchor on a typical night. I have been a power boater for years, have done a lot of anchoring out overnight and have never liked the chine slap at anchor if the wind is up.

October 4, 2018 at 9:04 pm

It all depends on the amount of wind and waves. Most nights, in a calm anchorage, it’s not noticeable. But if there are waves, you’ll hear them on the hull and you’ll hear some wave slap on the bridge deck.

JoAnna Mitchell says

January 25, 2020 at 10:21 am

Hi Carolyn, Thanks for this informative post! My husband and I are considering stepping up from our Hunter 30T to a Gemini 105MC. I have noticed in the listings that many have had the IO replaced with a standard outboard engine. What are your thoughts and what have you heard from other Gemini owners? Thanks for this page as well. We have used it a lot in preparation for our cruising future. JoAnna

January 25, 2020 at 12:35 pm

I know that many have made the switch but I think that more are still with the diesel. We did not want a gas engine as we simply didn’t want to carry that much gasoline on trips as it is MUCH more explosive than diesel fuel. However, they’re typically lighter weight and easy to have repaired or replaced should that be necessary.

Janet Smoot says

April 4, 2020 at 4:03 pm

We have owned our 2000 Gemini 105M for 8 years. We love it! We had a 25′ Catalina swing keel before that. Live the space..Plenty of sleeping for 4 people.The kitchen works great. Bought closed cell cushions for outside cockpit so very comfortable. Sail msilnly Potomac River and Chesapeake. But once we retire plan on longer trips. Works well for small grandchildren too. Can’t say enough good things about this cat. Never thought we could afford one. Gemini has now priced themselves out of the average sailor though. Thanks for the inciteful review.

Holly Henry says

October 8, 2020 at 11:03 am

Thank you for your website and information. We are looking at a 2000 Gemini 105M…it’s so difficult to find an MC. What does the MC have different that you would like? Thank you again for all of your information.

October 8, 2020 at 11:18 am

We have a 1999 105M.

Major changes in the MC:

• Mast is 1 foot taller and boom one foot longer, so mainsail is larger. Also bigger roach with the masthead crane.
• MC has an optional screacher.
• Seating at table is squared off, making it easier to nap on settees and huge difference in how easy the seats are to remove when you need to re-upholster.
• Table drops down to create a large bed for guests.
• Laminate centerboards instead of wood. Our 1999 M has the laminate boards, so it’s very likely the 2000 model does.
• Built-in air conditioning (this isn’t something we cared about, but it’s a big deal for many people)
• MC is 900+ pounds lighter, so it sails and motors faster with the same load.

October 8, 2020 at 7:08 pm

Thank you so much. Gemini’s are getting harder to find now that we are looking. Your website and info are invaluable to this part-time cruiser.

Mo Jacob says

August 13, 2024 at 11:49 am
