How do you judge the success of an ocean cruising yacht? You can tell a lot from where you see them and where you don’t. It’s also instructive to look at the builder’s order book. If you buy one now, how long will you have to wait for delivery? Another indicator is how well (or poorly) they hold their value on the secondhand market. By any of these measures, Neel Trimarans is absolutely nailing it.

You’ll often see Neel tris anchored in remote parts of the Hebrides and far-flung atolls of the South Pacific but they’re rarely seen in crowded, mainstream cruising destinations like the Ionian, the Virgin Islands or the Solent. Depending on which model of Neel tri you want, you’ll probably have to wait at least eight months and possibly up to two years. And a survey of brokerage websites suggests that there isn’t a great deal of difference between the asking price of a two-year-old Neel and the cost of a new one.

Despite the disruptions of the Covid pandemic, the La Rochellebased shipyard is still steadily growing. ‘We built about 30 boats last year,’ says Neel founder Eric Bruneel, ‘and this year we expect to build 45 to 50.’ The latest, smallest model, the Neel 43, is coming off the production line at a rate of one boat every two weeks and demand is still outstripping supply.

That said, due to the shipyard’s recently increased capacity, now is a good time to order a new Neel as the waiting list, at the time of writing, is shorter than it’s been in years.

Neel’s new Leen power tri have the same core values, and designer Bernard Nivelt owns one…

Neel is one of just a few brands that have carefully positioned themselves between these two extremes. ‘Where other multihulls have to choose between performance and comfort, a Neel combines both,’ says Charline Picon, an Olympic gold medallist the the RS-X class, who knows a thing or two about performance and is Godmother of the Neel 51. ‘We’re definitely performance-oriented but it’s absolutely not about racing,’ says Eric Bruneel, pointing out that while his yachts have performed very well indeed in ocean passage events like the ARC and ARC+, these are competitive cruising rallies rather than races.

Bruneel has a strong personal racing pedigree, having won his class in the 2004 OSTAR and 2005 Fastnet aboard the 50ft Trilogic, which he built himself, plus a second place in the 2006 Route du Rhum and various exploits in bleeding-edge C Class cats. He also has a lifetime of experience at the forefront of multihull production with 27 years at Fountaine-Pajot, including 10 years as managing director, before he left to found his own shipyard. In the decade since the first Neel trimaran sailed out of La Rochelle’s historic harbour, his boats have earned widespread respect among experienced ocean sailors.

So why choose a tri? There are several reasons why three hulls are better than two, especially if you’re sailing offshore. First and foremost: weight distribution, which is far more important in a multihull than a monohull. The central hull of a trimaran is the ideal place to put all the heavy stuff, Bruneel explains, and having a single engine amidships is much better for stability than twin engines at the aft ends of two hulls. ‘It changes everything, all the dynamics – like a skater in a spin, moving her arms in and out to control her speed,’ he says. ‘Catamarans have to carry weight in all four corners and that’s why the motion of a trimaran is better, much softer, at sea.’ The pitching motion is less pronounced when sailing closehauled and on a beam reach there’s less of a tendency for the boat to rock back and forth from hull to hull.

Another advantage is better performance in light airs, Bruneel says, which directly translates to more enjoyment for the owner and crew. The combined wetted surface of a trimaran’s main hull and one float is smaller than the wetted area of a cat with both of its hulls still immersed, and the trimaran is designed to sail with a small amount of heel, rather than bolt upright, which helps the sails hold their shape in very light winds. Also, a single rudder with a simple direct linkage gives a better ‘feel’ to the helm than a twin-rudder setup, particularly upwind, and saves weight in the stern where it has a significant effect on the boat’s fore-and- aft pitching motion.

The front end of a Neel 65’s bridgedeck has two separate lounge seating areas, either side of the yacht’s main nav station.

Neel’s ‘cockloon’, an original concept by Michel Joubert, turns the saloon and cockpit into a single indoor/outdoor space.

One of the Neel tris’ most useful characteristics is the ability to sail deeper angles downwind than most multihulls

Other key features include a cutter-rigged mast stepped amidships (long before it became fashionable to bring the mast step aft) with a big genoa and a working jib with a much lower centre of effort than the part-furled genoa of a sloop-rigged yacht; plenty of lateral resistance to ensure good upwind VMG – equivalent to a monohull racer-cruiser of similar length in almost any conditions – without needing a daggerboard; and the ability to sail efficiently downwind at deeper angles than most other cruising multihulls can manage, which is a distinct advantage for trade wind sailing.

Exotic materials are used only sparingly in the boats’ construction, for good reason. ‘We use unidirectional carbon only in crucial places like the beams and deck,’ Bruneel explains. ‘For long-distance cruising you don’t want carbon in the hulls because even a small hit can do a lot of damage to the boat, and we don’t need it because our boats are light enough without it.’ A carbon rig with square-top mainsail is available, which gives better performance than the standard alloy rig in light airs, but Bruneel says that in most conditions there isn’t much difference between the two rigs.

Almost all part of the boats, even the interiors, are vacuum-infused GRP foam sandwich using materials that can easily be recycled when the boat eventually reaches the end of its life. Social aspects of sustainability are taken equally seriously and the gender pay gap within the shipyard is actually tilted in favour of female employees. Environmental concerns are paramount even in the new range of Leen motor yachts. ‘I couldn’t ignore that even if I wanted to,’ Bruneel says. ‘My design engineers would simply refuse to produce a dirty boat.’

Converting an ole motor boat to a trimaran, AND sailboat

Discussion in ' Multihulls ' started by Lonejack , Oct 26, 2018 .

Lonejack New Member

Hi new friends, Just joined, love reading the various posts. Please don't kick me out of the forum for daring to broach this subject. I live close to a major river in the Western U.S. As my Bride and I drive around sightseeing, I see hundreds of motor boats sitting with weeds growing over them. I have seen where some here have converted a monohull to a trimaran. Has anyone attempted to convert a motor boat to a sailboat or a trimaran? I know it could be a slug, but one could sure have a lot of fun trying. My thought would be to find a free Hobby cat and use the amas for stability, mount a mast-aft and use furling jib and genoa. Lots of deck room and with tramps, would allow for a great swimming platform. River and small water only. Max outlay, $500.

What motor boats do you have in mind ? Planing hulls ?  

JamesG123 Senior Member

Those boats are usually laying derelict for a reason, bad motor or bad rotten hull. Either that is what got them there or that is where they are now after years (decades?) of being left improperly to the elements. If you have more time than money (or sense), then yeah, anything is possible. But it will hardly be easy. It takes a ton of not fun work to get those old hulks cleaned up and functional enough to put back into the water. And that is without trying to convert one to a motor sailer.  

These boats are mostly fiberglass. Wouldn't touch a wood hull. Almost 100% of these are planing hulls. I was just looking on Craigslist, there are many free boats offered, with trailers. I'm not planning on building an America's Cup yacht, just going to go through the process and have the fun of designing the craft. Probably will use unusual materials for the mast, rigging and sails. Yep, it will probably be a crude failure that ends up in the land fill. I'm looking for a weekend river cruiser. May race another Who knows... The challenge is intoxicating. I am a retired designer who was born and raised on a post depression wheat ranch, located 6 miles from the nearest town. We had to design. build and maintain most of our own farming equipment. My father patented a farm machine and invented a rotary steam engine among other things. I inherited his design bug. Love to design and build something from repurposed material. Hey, I'm retired, every day is Saturday, except Sunday. I have a full shop, Gotta do somthin.  

Get two planing hulls that are the same boat, and join them end-to-end (stern to stern), that way at least the thing will move through the water relatively easily, a planing hull has too much resistance.

$500.00 won’t get a “free” boat back to your house.  

kapnD Senior Member

As Mr Efficiency has noted, planing hulls make lousy sailboats, you need to do some research on efficient sail driven hulls before you move on the idea. I’ve seen powerboat hulls split in half to make catamarans, but that doesn’t really do anything besides making them heavier and more stable, and it’ll still be a powerboat hull, and a poor sailer.

There are lots of derelict fiberglass sailboats which would make a better main hull for a trimaran. Get the narrowest one you can find. Hobbie cat hulls don't have much flotation. If you can find Nacra or Tornado hulls they will work much better. All that weight will need more sail, not less. Perhaps an old Tornado mast/ sails would work. 16' Hobbie cat rigs are more plentiful and almost the same size. The mast is also shorter (5' less) and lighter. I got a whole boat for $100 a year ago. The hulls were complete trash, which is typical. There are articles about a Soling that was converted to a Tri on line, Google. Also a Chrysler 22 which seemed to work good. Good luck. $500 is probably a little low, but good for daydreaming! Keep updating this thread please - I want to see it. Marc

Ocean Eagle 43 construction

CMN finalised a contract with the Mozambican Government for the construction of three Ocean Eagle 43 trimaran ocean patrol vessels in September 2013.

The vessel is designed by NIGEL IRENS DESIGN, while structural building for all the three vessels was carried out by H2X under a contract signed with CMN in December 2013. Participants involved in the Ocean Eagle 43 programme also include Prezioso Linjebygg, ProLarge, and SeaTeam Aviation.

H2X rolled out the first Ocean Eagle 43’s central hull in July 2014 and delivered it to CMN shipyard in Cherbourg in September 2014. The second and third hulls were delivered in December 2014 and February 2015 respectively.

Design and features of the ocean patrol vessel

The Ocean Eagle 43 features versatile design and multi-hull structure comprised of a very slender main hull with two small floats. It is classified by Bureau Veritas classification society. Its hull and superstructures are made from lightweight composite materials such as epoxy, glass and carbon.

The vessel has an overall length of 43.6m, overall beam of 15.7m and maximum draught of 1.6m. It weighs 75t and can accommodate a crew of 13 personnel. It is equipped with a launch pad to operate fixed- or rotary-wing unmanned aerial vehicles (UAVs).

It is also fitted with a stern launching ramp to deploy a 7m outboard rigid-hulled inflatable boat (RHIB) for the shipment of goods, policing intervention, and other special naval operations.

Mission systems

Typical mission systems aboard the maritime surveillance vessel include electro-optical observation system, radar sensors, radio direction finder, command and control system, air-sea radio transmission of satellite data and an integrated navigation system.

Armament of Ocean Eagle 43 patrol vessel

The Ocean Eagle 43 is armed with one 20mm remotely-controlled gun turret and two 12.7mm side guns for self-defence.

The vessel runs on four 500hp diesel engines driving two controllable pitch propellers. It also incorporates three generating sets. Its carries up to 21m³ of fuel and 2m³ of fresh water.

TR42 PERFORMANCE CRUISING TRIMARAN

ABOUT THE TR40

The boat in the photo is Yana, the TR40 design of which a small number were built in the early 1990's. The TR40 was inspired by my experience cruising, racing, and living aboard my 33' trimaran Yellow Bird in the early to mid 1980's.

Regretfully no TR40's were built in Australia and to this day I have not had the opportunity to sail on one, although I have raced and cruised on the smaller Spoon Bay 10.6 which I designed just a few years earlier.

The TR42 is a current day version of the TR40. Float shapes have evolved, the centre of gravity has moved aft, and we'd prefer twin rudders because boats tend to get driven harder these days and you need the extra bite when you're flying the main hull. 

The design is very similar to the Rocket Factory trimarans, with the main hull, decks and cabin all built in kit form from flat panels. It could be a Duflex kit, or you could build the whole boat from full size patterns over temporary moulds. 

For a more bare bones high performance version of this design see the R42 here.

TR42 is available in aft cabin and open cockpit versions and some variations on the internal layout are possible in both versions.

TR42 ACCOMMODATION LAYOUTS

TR42 Trimaran Layout with single forward bathroom. The arrangement in the main saloon is interchangeable with the aft cabin and open cockpit versions.

There is quite a bit of flexibility with the layout on the TR42, for both the aft cabin and the open cockpit versions. I have presented these two options as a starting point. I have a personal preference for quarter berths while at sea, as I've stated elsewhere, but the aft cabin serves the same purpose. It gives quick and easy access to the cockpit if you're single handing or short handed.

For the aft cabin version I've moved the cabin forward from the transom a bit to make room for a boarding platform, dinghy stowage, and offering the option of using an OB motor as an auxiliary.

One advantage that comes from moving the forward beam and dagger case aft compared to earlier designs is that it provides a lot of space in the forward cabin. There is ample space to fit a head and shower forward of the beam BH and the forward berth is 1.5m/5' wide.

If you wanted a private owner's cabin forward it is possible to fit a second head and shower behind the dagger case in the saloon as shown in the open cockpit layout. This arrangement can also be used on the aft cabin version.

This arrangement shows the two bathrooms forward and once again is interchangeable with the aft cabin and open cockpit versions
