Concept. Marketing hype. No idea what's under the water line. Above the water it looks like a rip off of what Palmer Johnson has been building for years. PJ has moved on to the trimaran leaving these wannabe's in their (minimal) wake.

Like so many of these concept boats that never see the light of day.

Call 'em what you want - Dream boat, Concept Boat, Wannabe or Make Believe. They all succeed in one area...separating investors and first buyers from their money while someone else chases their pipe dream of building wealth by building boats.

Tad must bristle with such an article. Passagemaker lite predated these Dashew boats by a few years.

Long and relatyvely narrow boat

We ask to Joubert (naval architecte ) to do this type of drawing for us in 1994 it tooks to us finally 7 years to transform this idea to a "real boat" .
During few years we try to sale and built similar or near similar boat ...without succes !!
All (except Dashew ) fail to make any "serie" of such boat .
Because this type of boat as I wrotte on the first page of our blog concern a very small quantity of potentials customers...
Dashew have a big commercial machine behin him for example he get articles (in French Magazine )on the Windhorse just on the prodject.
At the same time our boat was already built and cruising .And we got just a photo and small article ...Because the principal is finally not the idea, the strenght, the consumption (for all of that our boat meet or exess the Dashew boats) but the commercial aspect and the feeling ...and the target (rich old people ?)
In the 15 last years we got just 4 potential Customer for boat similar at our .
We had some email exchange with Dashew when Windhorse was just a project and we wrotte it could be more usefull a hull like our without keel and with solid bottom ...and when we take a look at the 64' evoltution we can clearly understand that this idea was not stupid but one idea is not all (look at the Tad Robert 56' I like this concept but how many was sold !?)

Next monday a Customer come to buy our Long-cours.62 ...normally after that we will built 2 similar évolutions at far less price than Dashew 64'.
Even cheaper than the Arknautica 58' ...but without marketing sure it will be 2 boats and never more .

On the 58' Artnautica , the only "problem" is : I don't be able to keep a boat so light for feel confident with him and be able to charge her for real "passagemaking" books, Tools, diesel, food, water, spare parts etc etc it means tonneS.

And or the abillity to cruise in no good weather conditions until we don't get film we lateral short wawes ...

For the rest congratulations to take the risk of built your dream .

I like you longcours62. I've seen some of your sites and drawings.

It's nice to see some of your original ideas, though you clearly seem to know that there is virtually no market for such a boat.

Also, it's nice to hear someone's viewpoint other than the Dashew shills.

Good luck

It seam to be necessary to precise : we are not Professional boat builders and (as you can read on our blog !) we are not making marketing here.
As wrote on some post years before we stop (long time ago ) to try sold and/or built boats similar to our actual one .

And when above we wrote we will built two similar (if the potential Customer still want buy our actual) it will be a built for me and a colleague on the (sorry I don't know the right term in English) "self made" "own built" "do it yourself " basis.
Just take "chaudronnier" and welder, rent a "warehouse" and built our hull/boat.
It is manly why we project to get her below 1/8 of a Dashew 64' if we do all by ourself and 1/6 if we make the hull and arrangement in professional boatyard and carpenter.

Or , may be , built totally the boat with a fiberglass boatyard who want built similar boats to our actual...?

Here is another new LDL (longer, thinner, low displacement to length) boat design that is being built right now.

It seems that this design might appeal more to the traditional trawler type of people.

"Johnson Yachts, based out of Pine Harbour Marina in Auckland, New Zealand, are in the process of building an 80-foot launch for a NZ/Canadian couple living in Australia.

Designed in collaboration with NZ yacht designer Kevin Dibley, this new project will be marketed as the Johnson 80 Motoryacht, Designed as a light displacement-to-length motor launch (LDL), she is designed and built to Australian NSCV LR SSC-2B survey requirements.

The design brief to Dibley was for a vessel that has a sleek and low profile, and a very stable and highly efficient hull form. A go anywhere, anytime launch that the couple could use with family and friends both here and abroad. The interior had to allow for good entertainment with a large groups, but also comfortable and private for smaller groups and charter."

Power trimaran

Originally Posted by LRC58Fan View Post

The Ocean Eagle 43 is an innovative OPV (Offshore Patrol Vessel) that has been designed to offer a cost effective and reliable vessel for governments and research agencies to operate for extended periods at sea.

Ocean Eagle 43 trimaran will have a range of over 3,000 nautical miles and a top speed of 30 knots whilst burning around one-fifth of the fuel of an equivalent single hull OPV.

Built in lightweight composites and powered by four 500hp engines, the 75 tonne vessel can be operated by eight crew or less offering a much lower cost of ownership, both in build and operation, than an equivalent single-hull ship without compromising the operational performance and ability to carry out effective patrols.






A response to the changing needs of modern navies with greatly reduced acquisition and operations budgets, the Ocean Eagle 43 is a light ocean patrol vessel (OPV) that makes use of modern electronics for multiple missions — many of low intensity but high economic import, such as anti-piracy and surveillance of fishery, oil and gas and other maritime resources. Constructed of composites by Chantier Naval H2X (La Ciotat, France) for shipbuilder CMN (Paris and Cherbourg, France), the new 43.6m OPV benefits from CMN’s 68 years of surface-combatant craft experience and construction of hundreds of advanced vessel designs for 38 navies around the world. Part of the Ocean Eagle’s versatility comes from its sleek and fast trimaran hull, which also offers a beam (width) that can accommodate a landing platform for unmanned aerial vehicles. A renowned shipyard in its own right, H2X’s methods contribute to the trimaran’s favorable performance-to-price ratio and have earned its builder the record for the largest hull ever infused with epoxy resin in one shot.

Designing for efficiency

Conceived by legendary naval architect Nigel Irens, the Ocean Eagle 43 is a descendent of his multi-hull designs, which dominated international sailboat racing for decades. ...

“It’s taken many years for the world to warm up to this design for an efficient surveillance vessel,” notes Irens, “but it is a perfect application for a trimaran.” The long, slender main hull and diminutive outer hulls (called amas) provide exceptional stability but weigh less and experience less drag than other hull forms of comparable displacement, including twin-hulled catamarans. “The trimaran offers the greatest range … due to its very low wetted surface area,” he explains. “What you get is a top speed of 30 knots for Ocean Eagle, but more importantly, a very economical 20-knot cruise for a 4,828 km range.”

Delivering versatility

The first three Ocean Eagle 43s will be delivered to Mozambique in 2015. CMN has been so pleased with the design concept that it introduced a mine-hunter version of the Ocean Eagle 43 in Le Bourget, France, at the 24th International Naval, Defence & Maritime Exhibition (Euronaval, Oct. 27-31, 2014). The company says it now offers an “ideal” solution for navies seeking simple, modular and versatile platforms, which can be assigned not only to surveillance and minehunting, but a variety of other patrol missions.



Check out some great images of the finished boat here at the CMN Web site:

It was our first idea in 1990,

Le concept - Trawler long-cours

In 1993 we thinking a more "conventional" trimaran like the
"cable & Wireless" we like this form but as you can read on the first page of our blog we became more reasonnable because "long light and narrow" boat is difficult to sale but a "long thin narrow" power trimaran it is near "mission impossible"
In a 22 m lenght power trimaran you get the same volume than in a 12m classic motor boat ... It is acceptable if you never go in marina !! 22X8 m

But even if it is not reasonnable I like the look of a power trimaran.
But one time I got the oppotunity to discuss about power trimaran with Nigels Irens ans his remarque was : not sure than the drag of the 3 hull of a tri is more efficient thant the drag of the 2 hull of a catamaran ... And I thinks he know the subject

Some of these boats are relatively radical. The typical trawler in comparison is also radical when it comes to beam length ratios in the other direction. There has been a long trend toward fatter more cottage type boats to get more room and interior. Often a bigger or more powerful engine no side decks and three levels goes with the formula at some cost in efficiency. Back when engines were not so powerful the norm was a much narrower low profile low CG boat. As a result trawlers which are supposed to be efficient are not relative to boats with longer WL less beam and less wind age. Take the typical trawler shave 5 or 6 feet of beam get rid of the top two levels and all the weight that goes with it and Walla a much more efficient boat long and lean.
