Histoires sous le vent 22 Posted April 12, 2020 Share Posted April 12, 2020 39-foot offshore cruising trimaran project This harmonious design by Philippe RIVIERE (Philippe RIVIERE / Yacht Designer | ARCHITECTE NAVAL http://www.philipperiviere.com/wp/) of classic design (without giving way to reverse bows), offers two double berths - including the one at the rear located at the waterline which should turn out to be very pleasant at sea -, a shower room wc, a chart table corner, a small "L" seat (which can be used as extra sleeping) with its table for meals and a long kitchen facing it. All the fittings benefit from a beautiful height under the beam and a sufficient height above the berths to be able to sit. Storage should not be outdone given the volumes still available. Outside, this trimaran is distinguished by its large cockpit which extends along the rear arm with two deported and protected helm stations. Two watch stations are located in front of the descent, which are sheltered by a large hood. Particular care has been taken to facilitate access and safety on the deck by gangways placed on each side of the deckhouse which turns out to be very slightly domed and slightly raised. On the power side, the trimaran has an upwind surface of around 85 m² for a mast of 15.40 meters. The mast height and the sail area are reasonable, but they could be increased according to the wishes of the future owner. . This sorting is provided with bulky floats. The design, with slightly V-shaped bottoms, should encourage a more comfortable passage in the rough sea and above all should be more tolerant in the event of overselling. The foils remain optional ... This trimaran can be built in foam or strip planking LENGTH: 11.90 M. WIDTH: 10 M. WEIGHT: 3000 KG TRAVEL: 4000 KG WING MAT: 15.40 M. SAILS AREA: 83 M2 MOTORIZATION: inboard 30 cv Could be suitable for a Route du rhum. Quote Link to post Share on other sites

Histoires sous le vent 22 Posted April 30, 2020 Author Share Posted April 30, 2020 Some modifications. The mast has been moved back, the daggerboard is located in front of the mast. With a mast retracted, the presence of the bowsprit is less useful or necessary. the dinghy finds its place at the rear of the cockpit beam. It should also be noted that the buoyancy volume has been increased on the rear of the central hull Quote Link to post Share on other sites
PIL66 - XL2 1,074 Posted April 30, 2020 Share Posted April 30, 2020 This rig appears to short .... what is the reasoning for this...? Quote Link to post Share on other sites
Histoires sous le vent 22 Posted April 30, 2020 Author Share Posted April 30, 2020 I am a French guy. I don't always understand English perfectly. What do you mean ? Why is this trimaran so short? The first question to ask for a new boat is: what size of sail I am able to maneuver. For me, I am not very young, a hundred square meters alone ... 40 feet is also the minimum to face a little rough sea on a multihull. It is also the minimum size that provides sufficient comfort for a couple. Finally, a moderately sized trimaran limits the cost. 1 Quote Link to post Share on other sites

triple jim 15 Posted May 3, 2020 Share Posted May 3, 2020 Philippe Riviere is a very talented architect with too few boats built ! I had the opportunity to sail along with Prana, a 45' trimaran he designed. She's a pretty fast boat. Quote Link to post Share on other sites

unShirley 256 Posted May 3, 2020 Share Posted May 3, 2020 18 minutes ago, triple jim said: Nice looking too.. I see some Newick influence there. Re: short mast. I did a lot of sailing on two different Vals in the 80s and early 90s. I really appreciated the short mast when the wind piped up. And they were both light enough to still do pretty well in light winds. But, honestly, I hate light wind sailing anyway. So I like a short stick to keep the weight aloft down. Having a bunch of stick waving around up there above a reefed sail seems a bit dicey. Quote Link to post Share on other sites

boardhead 330 Posted May 1, 2021 Share Posted May 1, 2021 This boat is way similar in spec to the tri I have been enjoying for thirty years - what Formula 40 should have been. I really hope this comes to fruition before marina dwellers and older folk f it up - Good Luck and stay true to the concept. 5 Quote Link to post Share on other sites
