Hunter 41 DS

• By Nim Marsh
• Updated: June 2, 2006

What luck! This blustery fall day on Chesapeake Bay, yacht designer (and Hunter’s director of engineering) Glenn Henderson would sail with us aboard one of his team’s creations, the shoal-draft version of the Hunter 41 DS, a spin-off from the year-old aft-cockpit Hunter 41. We joined the deck-saloon sloop by launch as it luffed up in Eastport’s lee, near the mouth of Back Creek in Annapolis, Maryland. People and gear were quickly pulled aboard, and Henderson was champing at the bit to tell me his baby’s story. “First off,” he said, “I wanted a boat that would have all the systems and conveniences you’d expect in a house and also be capable of long-distance offshore passages.”

I looked down the broad decks–the 41 DS has a 3:1 length-to-beam ratio–held high above the water by substantial freeboard, and I thought that the first part of the wish was eminently possible. But I also wondered, would she sail? So many builders of successful designs have pushed the interior-volume envelope so far that their creations no longer effectively harness the wind.

We cracked off in very light air, heading for the unprotected waters of the bay. I was visibly surprised when the boat-with a modest 17.2 sail area-to-displacement ratio–responded dramatically, accelerating as the optional Selden in-mast furling main and Furlex roller-furling genoa filled. Henderson had been watching for my reaction, and when he got what he wanted, he said, “Sail area/displacement doesn’t always tell the story. Right off the bat, I try to make my hulls easily driven. Of course,” he added with a wry smile, “they put three-bladed props on them, but I can’t do anything about that.”

Coaxing the Coefficients Henderson then explained that with each boat he designs, he tries to push one of the design coefficients: fineness, block (underwater volume compared with a block with the same overall dimensions), midship (the ratio of underwater fullness to that same block amidships), or prismatic coefficient (Cp). For the Hunter 41 and 41 DS, he decided to push the Cp, a mathematical description of how full a boat is in the ends.

“The extremes for sailboats are between .49 and .62,” Henderson said, the higher figure equating to fuller ends. The higher the Cp, the more stable–and sluggish–the hull form. While trying to pick the ideal Cp at one point on the hull and determine an optimal speed-to-length ratio, it occurred to Henderson that the Cp is a single number that defines two different ends but treats them equally. “So I decided to cut the boat in two at max beam and make a graph of stern and bow Cps,” he said. Henderson analyzed the numbers from past Hunters, then extrapolated the ranges to the behavior of the respective designs. “I then could safely take that data and apply more radical treatment [to the 41 DS] and yet be safe that the boat wouldn’t be over the edge,” he said. The numbers he arrived at–lower Cp for the bow, higher for the stern–had the most effect on boat speed and motion.

The boat accelerated well in both light and heavy air, and it got up to speed quickly as we cleared Horn Point and took head-on the full 18- to 20-knot brunt of a northeasterly wind. While the seas weren’t large, they were sloppy and persistent, and the 41 DS coursed easily through them at more than 6 knots, the helm delicate and responsive as we picked our way through wakes and around crab-pot buoys. A stem closer to plumb not only increased the waterline but also reduced pitching.

For Henderson, responsiveness in the 41 DS was an important factor. It’s a “largish” boat, he said, and it’s likely to be carrying a number of passengers, with only one or two familiar with the boat. He wanted to make this boat as maneuverable as possible in crowded situations-wharf areas, marinas, crowded harbors, any tight quarters. The Whitlock direct-drive steering system and balanced spade rudder with a stainless-steel rudderstock certainly help to achieve this. “Responsiveness is also a good attribute when sailing in really rough seas offshore and steering through waves,” he added.

Versatile Deck Layout

Out in the bay, the 41 DS was steady and smooth as we put it through its paces. I’m 5 feet 7 inches tall, and I found the visibility forward, over the dodger, excellent. Where once the mainsheet was led solely to the cabin top, strategic positioning of hardware and winches allows the solo crew to trim from the companionway–or the gregarious skipper with a cockpit full of guests to run the boat from the fantail. The mainsheet can be led from the cabin top and sheeted on the spinnaker winch, creating little interference with the cockpit. When in port, the 40-inch wheel folds out of the way to create more space for socializing.

The side decks are wide and graced with a terrific nonskid pattern. The first time I went to the foredeck, I felt secure, bracing myself on the stout handrails on the dodger and the cabin top. Slippery areas existed, though, around the forward hatch and on the corners and visor of the house.

With 777 square feet of working sail (we sailed with the optional vertical-batten in-mast furling main) on a 19,400-pound displacement, this Hunter isn’t overcanvased. Yet in 13 to 15 knots of wind on a truly messy sea, we logged close to 7 knots of speed, accelerating with every gust but never overpowered. “I’d rather have a boat that’s easily driven and, at the same time, manageable and able to sail in relatively stiff breezes without reefing than one that excels in light airs to the exclusion of high-wind performance,” said Henderson.

The most impressive aspect of the 41 DS was how quickly it was able to accelerate. Henderson said he achieved this by pushing the volume forward so the stern corner was out of the water, which flattened the stern wave. “Hull speed is derived from bow and stern waves,” he said. “If the boat goes too fast and gets too far ahead of the stern wave, it falls into a hole. So, by virtue of an S-shaped curve at the quarters, I artificially induced a wave to form farther aft, which in essence increased the waterline length and the boat speed.”

When I went below on the wide companionway steps, holding on to perfectly positioned grabrails, the ride was smooth and quiet, even though conditions outside were anything but. Later, when we ran the 40-horsepower Yanmar with a conventional shaft at 2,500 rpm, the noise level remained low.

Light and Airy Saloon

Upon entering the saloon, I was struck by the awesome, 6-foot-10-inch headroom and the light and airiness created by the raised deck. Just forward and to port of the steps is the L-shaped galley. Corian countertops (with an inset waste bin and, to protect the dinette, a clear backsplash with rounded edges) are surrounded by high, inward-curved fiddles, which do double duty as grabrails as you prepare meals and approach or descend the companionway. These ergonomic fiddles are found throughout the boat along shelf edges over settees and in the cabins. In the galley, at the stove, a harness will be needed, especially when on port tack.

The double sinks, positioned diagonally in the angle of the L, would take some getting used to while washing up in a seaway. Aft of them is a gimbaled two-burner propane stove and oven, with a microwave set above, and a stainless-steel front-loading fridge. The pantry, with shelves and a deep bin, is worthy of any small home, and there’s in-sole storage for cans and jars. With two opening ports, a hatch, and proximity to the companionway, galley ventilation will be superb. Forward of the galley is the dinette; all three seats could serve as extra berths while on passage, and the table, with telescoping support, converts to a double berth. A vertical stainless-steel grabrail is conveniently located between the galley counter and the dinette.

The aft head/shower stall, with two frosted opening ports, is to starboard of the companionway; just aft of it is the door to the aft cabin, with its athwartships queen berth, private entrance to the head, Corian-topped vanity, cedar-lined hanging locker, and lots of drawers. With two opening ports and a hatch, cross-ventilation will be excellent. The forward-facing nav station, forward of the head, has a radiused, battened seat for comfort and efficiency in a seaway, a lift-top desk with more of those seamanlike fiddles, and a mahogany console on which to mount remote instrument readouts. Opposite the dinette is a full-sized couch, with a large drawer under and, on the boat we sailed, a plasma-TV and sound system over.

The forward cabin, with 6 feet 2 inches of headroom, has a comfy double to port, with fiddled shelves all around and drawers under. To starboard is another cedar hanging locker and a Corian-topped vanity. The head/shower is in the peak and, thus, only usable on a flat sea or in port.

I stepped off this Hunter impressed. The 41 DS seems to cover many bases and includes many details in an attractive package that really works. Apparently, Cruising World’s 2006 Boat of the Year judges also think the Hunter Design Group is on the right track: The 41 DS was voted Best Production Cruiser 40 to 44 Feet (see “Crunching the Numbers,” January 2006).

Also noted by the BOTY judges was Hunter’s attention, throughout the boat, to American Boat & Yacht Council (ABYC) specifications, anticipating, in at least two cases–carbon-monoxide and smoke detectors–future ABYC recommendations. One judge, ABYC curriculum designer and senior instructor Ed Sherman, said, “I think the build quality is much higher in terms of fit and finish. It certainly represents a lot of bang for the buck.”

But for me, it was the Hunter’s performance that stood out, which I reiterated to Henderson. “My primary objectives were high stability, boat speed, a good motion in a seaway, and reactivity or responsiveness,” he replied. “These four attributes make up what is commonly known as ‘performance.'”

HUNTER RESPONDS

We trust that you, too, will be as impressed as Nim Marsh was, and we feel it appropriate that the Hunter 41 DS not only earned the 2006 Cruising World award for Best Production Cruiser 40 to 44 Feet but also earned the 2006 Cruising World Overall Best Value award.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Hull Length: 38.67’/11.76m Shoal Draft (wing keel): 5’/1.52 m) Ballast-Shoal: 6612 lb./2999 kg P(Furling): 50.67’/15.46m E(Furling): 19.5’/5.95m

Hunter 41 AC Builders Plate

• Thread starter deekster92
• Start date May 23, 2024
• Hunter Owner Forums
• Ask A Hunter Owner

Hey guys. A friend and I are attempting to start up a little day charter with our newly acquired 2008 Hunter 41 AC. Some items we are missing to proceed with the process are "Builders Plate' information stating maximum persons / weight allowed on board that you usually see affixed to a vessels hull usually in the cockpit area. We have not been able to locate this plate on the boat or see reference to it online. The 2004 manual states that there is a builders plate affixed to the boat but does not show a picture of it. The 2008 manual that we have doesn't even mention the plate. I can see this information provided on other Hunter boats manuals for instance the 40.5 shows a capacity of 10 persons. Another item we are missing is any documents detailing the buoyancy, flotation, or stability of the vessel. I was wondering if anyone with a Hunter 41 produced from 2004-2012 may have a builders plate on their vessel that they may be able to share the information with, and if anyone knows anything about the other document on stability that our governing body is asking us for. Any information would help a lot, Thanks, Derrick  

SBO Weather and Forecasting Forum Jim & John

You need your Hull ID number which normally found on the Rear Starboard side. Jim...  

More information that will help them is here Hunter 41 AC — Sailboat Guide Jim...  

You can get a complete History of your Hunter 41 here Boat VIN Lookup / Hull Identification Number Lookup | Boat History Report about $80 USD [free for first look] Jim...  

Thanks James, I do have my Hull ID number. When originally submitting stability and buoyancy I attempted to use information showing specifications of the vessel with information like the comfort and capsize numbers but apparently this is not quite what they were looking for. I pulled up and information through the boat VIN lookup you linked that didnt give me much information either other than telling me that it has been accident and damage free and some basic info like hull material etc. Thanks, Derrick  

ice breaker

I have a 2004 and have never seen the plate. And I have been everywhere on the boat. The CE classification is A/10.  

Thanks Ice Breaker, This does help, I can see in the 2004 manual where it states a better compliance notice than the 2008 model. In this I can see where it states the A category, but can I ask where you got 10 from? Thanks  

twalker H260

You likely won’t find a “builders or conformity plate” as I think that is a Canadian (Australians have a version) thing only. On our 2004 260 we had to go through a lot of hoops to get one issued from transport Canada - if I remember correctly it was issued as a self built. Hunter and our broker who we bought our boat from (- new in 2003)were not helpful as they seemed to know nothing about its requirement. We were eventually able to connect with a person who sat on a govt board/committee that advised transport Canada on the regulations - they assisted us in obtaining a “one off” plate. You might want to contact your local MP for assistance. It is disappointing to hear this continued to happed for several years after our experience. Not sure if it’s still happening now.  

Hey Twalker, Thanks for your input. I have reached out to Hunter, but would be surprised if they came back with the information that I would require even though I believe they would or should have this information pretty readily available. I'm sure if I were to buy a brand new Marlow-Hunter this information could be requested prior to sale and they would be more inclined to provide the sufficient documentation required. I am with Transport Canada as well and it may be looking like I have to go through these same hoops, including having a stability assessment done and I believe something along the lines of what you described above. Thanks,  

Thanks, Unfortunately no A in my Hull number but there is a D. I can find the CE of A/10 for the hunter 41 DS in their documentation which is near identical mostly just a raised cabin so im sure it is A/10 it just seems impossible to find on the AC

Category A 10 People All I can contribute to help you. Jim...  

That is exactly what im looking for, however does not seem to exist for my vessel. https://www.marlow-hunter.com/wp-content/export/Owners-Manuals/40.5%20Owners%20Manual.pdf This manual shows on page 34 a compliance style letter stating that on page 35 a builders plate copy is included in manual, in which of course on the next page shows the plate. on the 2004 Hunter 41 AC Manual ( https://www.marlow-hunter.com/wp-content/export/Owners-Manuals/41 Operator's Manual 2004.pdf ) It states on page 34 the same style compliance notice stating on the next page 35 will be a copy of the plate and of course the next page is not a builders plate which is super frustrating.  

Thanks Jim, I really appreciate your help, I am aware now that my boat is certainly 10 people CAT A. I just cant tell that to Transport Canada with no proof. But I will try and use the A/10 from the form I found on the DS variant and I will hope they will accept that. Thanks
