HenrikB 0 Posted November 24, 2008 Share Posted November 24, 2008 Me and a friend designed a 22ft tri, it is now under build in Sweden! The concept is a daysailer with possibility to sleep one or two. We also wanted performance but not on the edge so that it gets tricky to handle when sailing alone. The dimensions was limited by my friends basement, where the boat was to be built. Length 6.5 meters, beam 5.5m. Main hull is 1.4m, that was limited by the door that is 0.71m (main hull is built in 2 halves). Daggerboards and rudders on the amas. The light displacement is 300kg, sailing displ is 600kg. Sail area upwind 33m2, downwind about 80m2. The amas are designed with volume enough for flying on one hull. All carbon and epoxy. Hull, amas, beams anre completed, except final finnish. Next step is the mast, it will also be vacuumbagged in the basement All fittings are Harken, Sails are North 3DL. Plan is to have it on the water summer -09! Some pictures attached.

HenrikB 0 Posted November 24, 2008 Author Share Posted November 24, 2008 Thank you for the kind words! Build hours is alot for a multi. Compared to a "normal" boat, you have to build alot more parts! The total build cost is as usual more than you first plan... I think it will end up at about 25-30000$. Link to post Share on other sites

The 600kg is max sailing displacement with crew of 3, motor, food, tent, cooking stuff etc. Empty displacement is 300kg. That is about the same as the multi 23, however, this boat has a lot more volume, and is much stronger built. It is designed for offshore sailing. Congrats, awesome project. Who did the engineering design work for you? How many hours into the project so far? Would you do it again? We have done the engineering and design work our selves! We have both built/designed boats before, and I am used to 3D modelling. I was new to surface modelling, but we got it together quite nice I think ;-) I don't want to think about the hours... We have both built boats before, so I guess that means we are doing it again Link to post Share on other sites

bushsailor 96 Posted December 5, 2008 Share Posted December 5, 2008 Now I am building a similar boat 23' long very thin wave piercing hulls. Should be very fast. I have a proto type made out of old beach cats that shows what potential is there. It has not got enough boyancy and is very wet but it cuts through the chop beautifully. The next version will deal with the spray and bouancy problems. The other issue is tacking. It tacks ok but the jib needs to be held until the boat is well on the oposite tack. Is this normal for lite weight tris? It sailed straight past a F24 on a reach last week, and the F24 was running a screacher and I had a tiny blade jib. I estimate we were about 20% faster. I will not be selling this new boat but may sell the hull mould when it is finished. I have also decided to put rudders on floats as I have discovered that when pushed on a reach the main hull lifts and air gets sucked down the rudder at about 19knots+ I also have to sort out the folding system and structural design of the beams. Any help with a simple lite folding system would be greatly appreciated. I am leaning more towards folding beams with strut, but was also considering carbon sliding beams similar to L7. Beam is retricted to 5.0m using sliding system. I would prefer about 5.4m Any structural advise would also be greatly appreciated. Total sailing weight is targeted at 300kg and cost gestimate around $28000.00au I copied this from another post but it gives some idea what I am trying to achieve. No cabin, light weight racer similar to Multi 23 but folding. Main hull does not have the rocker of the M23 and has chines on the rear 15% to let reduce drag at speed. The test boat which will be the plug is currently cut in half (again) but I will get a photo soon. Max waterline beam is 300mm. We will vacum infuse the hulls and beams.

Henrik, Drew & Manshed, Love your photos Henrik and looking forward to your Drew. Great progress Manshed! We also are building a 23 foot trimaran in NW Washington, although we have taken a different approach. We have collected used parts and pieces from an assortment of boats, and are modifying them to fit together. Total cost will be about $10-12,000 US, although it will not be nearly as pretty as your boat Henrik! We obtained a 23' L-7 ama from Mike Leneman and widened it for our main hull, and a Nacra 6.0 Extreme from FL, which we have lengthened to 23'. We also purchased a broken Mumm 30 mast and some cored carbon panels from Russell Brown, which we will use as our crossbeams, bulheads, floors, etc. Finally, we obtained a carbon mast off a modified "Cathouse" Nacra 6.0. The Nacra Extreme was modified by Randy Smyth and has larger sails, a 100' jib, and a 400+ spin. So far so good, I spent all morning working on it in the garage. Weight should be comparable to Multi 23 as well, but our goal is to make it faster to put together, less dihedral, and less squatty going upwind than the 23. Hope to have it finished within the next month or so, before foul weather takes over here. Henrik, I love your ama sterns, they should plane rather than squat! Will probably start my own thread when we get some photos uploaded. Cheers, and keep us all posted, Mark Link to post Share on other sites

Steveromagnino 2 Posted October 13, 2009 Share Posted October 13, 2009 A friend and I plan to build this beastie. more of a daysailor and a far bit lighter than the Multi or the 7m cabin style tris. Could be fun. Like a sportboat with amas in concept; fun to sail for 2 or 3. 6m approx. Gonna race it in Asia for a bit; fits into a 20 foot container, can be packed up like a weta. At least that's the theory. Really interesting to see the 22 footer which is just a tad bigger, but not so different in concept. The great thing about this sort of size is that like a sportboat, you get a massive return for not too much investment in cost. I guess that's why the weta does well, but for me that's a tad too small; I need something that i can race against farriers and corsairs and the other sandal wearers, not the beach cat beer swillers.

Steveromagnino 2 Posted October 16, 2009 Share Posted October 16, 2009 TC design, yep. After accumulating a lot of rigs, parts, etc, I had the desire to have a boat I can sail at high speed.....so the tri seemed like a nice solution; good for Phangnga and the like - will stick to pornstar action for the Samui regatta but could be fun for some of the others. We have another mate who also wants one, so keen to build two together for some fun. Something like a big weta (which TC also designed although somehow has not been credited for). Less than 300kg and fits in a container plus easily trailerable. How is the biplane coming along???? We also have some plans afoot to sort out the sportboat rules next year and get fair handicapping; perhaps going to an online prize plus a PHRF or SMS system for handicaps; the E7 is rated criminally high; platus are crazily low - we can fix now.

We also have some plans afoot to sort out the sportboat rules next year and get fair handicapping; perhaps going to an online prize plus a PHRF or SMS system for handicaps; the E7 is rated criminally high; platus are crazily low - we can fix now. Yes, Tim Clissold was indeed the designer of the Weta - as indicated on his own web site but I understand there were some 'royalty' issues over the Weta design based on the original concept and what the boat was to be used for as opposed to how it was then developed commercially by the guy who commissioned the design. The first of the two new Samui bi-planes was launched late Sept. by KT - this is based on the 750 hull lines we commissioned from Tim but had the sheer 'chopped down' and turned very much into a lightweight minimalist 'hot cat'. Name was changed from Project X to 'Storm' and by all accounts easily achieved over 20 knots on test sail in winds of around 14 knots. Our revised version, in planing hull format, now has all the components completed and coming out of the molds to finish ready for joining and assembling the prototype. Should be around same weight as Storm at approx 650kg but (as you know) will carry the stayed CF rigs from C-Tech. So in addition to the normal 2 x mains we carried on the RB's (and as currently fitted on FS rigs on Storm) we will also be able to fly a 50m2 assy. Very much looking forward to some fast fun sailing in the near future. Link to post Share on other sites

Very impressive work, Henrik! Inspiring too! Care to share some details about how you built the mast? Materials and methods? Gert The mast was built by joining 4 pieces. A mould was built for a "quarter piece". Main reason for not doing it in just 2 halves was that the workshop is not long enough. The mast is carbon/epoxy, vacuum bagged. After producing 4 pieces in the mould, upper and lower part was built by joining the two halves. Upper and lower part was than joined with a sleeve on the inside. Also, the spreaders are attached in the same area. The final result is very good, the mast is very stiff, could probably been built a bit lighter... Weight is about 2kg/m, mast track and spreaders included. Some pics attached! Link to post Share on other sites

Qucifer 0 Posted October 29, 2010 Share Posted October 29, 2010 Is that a Facnor structural furler on the jib? An STG 3T? I have one of those on my Corsair... Do you have the furling line going through a couple of rope clutches? That seems like an interesting way to go... I don't like how the continuous furling line is set up on my boat right now.

HenrikB 0 Posted October 29, 2010 Author Share Posted October 29, 2010 Yes, that is the Facnor furler, worked ok for a couple of days until the upper swivel got stuck due to destroyed bearings. There was no grease in it at all! We took the furler of and put hanks on the jib instead, works much better! And shape of the jib is also better with horizontal battens. The rope was only going trough one camcleat on the "pulling end", worked fine! Is that a Facnor structural furler on the jib? An STG 3T? I have one of those on my Corsair...

I've also been thinking about ditching it and just going with a conventional forestay. I may have to take a closer look at my upper swivel... that's definitely where mine is hanging up... but I thought one of the other halyards may have been fouled in it and causing problems. I'll have to check things out more closely. Link to post Share on other sites
HenrikB 0 Posted October 30, 2010 Author Share Posted October 30, 2010 A short vid from sailing the tri. 16kn flying on one hull http://www.facebook.com/v/418892766378 Pictures here: http://www.facebook.com/album.php?aid=188128&id=619936378&l=8a1bc65083 Link to post Share on other sites
HenrikB 0 Posted October 30, 2010 Author Share Posted October 30, 2010 Top speed so far, about 21kn... The same day we were sooo close to flip it over, we got a litle bit more careful after that Link to post Share on other sites
eric e 9 Posted October 30, 2010 Share Posted October 30, 2010 thanks for the video and pics Henrik certainly a beautiful boat and amazingly "factory" looking for a "1-off homebuilt" the mast and mast rotator arm look BETTER than many factory offerings are there any things you would do differently if/when you build boat2? in the video it's good to see the bow clear of the water at speed a video of a tack or gybe would be great as would some video of the leeward ama bow when reaching at speed Link to post Share on other sites
HenrikB 0 Posted October 31, 2010 Author Share Posted October 31, 2010 thanks for the video and pics Henrik certainly a beautiful boat and amazingly "factory" looking for a "1-off homebuilt" the mast and mast rotator arm look BETTER than many factory offerings are there any things you would do differently if/when you build boat2? in the video it's good to see the bow clear of the water at speed a video of a tack or gybe would be great as would some video of the leeward ama bow when reaching at speed The weight ended up at 470kg (about 70kg more than desing weight), building #2, it would be lighter, the boat is rock solid with potential for weight savings. Also, the bows on the amas would probably be possible to make finer, we added quite alot of volume in the upper part. Also, it is very important in light air to keep weight forward, I think it would be possible to "rotate" the amas, lifting the bow compared to main hull. That would help lifting the stern of the main hull a little. On the other hand, the boat is a dream to handle in air, absolutely balanced and very nice to fly on one hull. Bertil is now working on mods for next season. New retractable bowsprit, a screacher will be added, anti skid on the "deck", new spreaders angeled more aft, and other small fixes.

Easy-Sailing.dk 1 Posted November 9, 2010 Share Posted November 9, 2010 The project is moving on, boat is now ready for final paint!Mast is built, rudder and daggerboards still remains. Very impressive work, Henrik! Inspiring too! Care to share some details about how you built the mast? Materials and methods? Gert The mast was built by joining 4 pieces. A mould was built for a "quarter piece". Main reason for not doing it in just 2 halves was that the workshop is not long enough. The mast is carbon/epoxy, vacuum bagged. After producing 4 pieces in the mould, upper and lower part was built by joining the two halves. Upper and lower part was than joined with a sleeve on the inside. Also, the spreaders are attached in the same area. The final result is very good, the mast is very stiff, could probably been built a bit lighter... Weight is about 2kg/m, mast track and spreaders included. Some pics attached! Hi Henrik Could you please tell a little bid more about the mast you build? I would like to know some more about the layup plan, dimensions and so on. The boat looks great and the work you have done is an inspiration to all of us. I am currently working on a small F28 trimaran project in Copenhagen. Best regard Mads Link to post Share on other sites
MartinRF 0 Posted May 15, 2011 Share Posted May 15, 2011 Henrik, did this boat just do the Round Lidingö Race? I was not there but the preliminary results list shows a one-off trimaran that caught my eye. /Martin Link to post Share on other sites
suigeri 0 Posted May 15, 2011 Share Posted May 15, 2011 No, it was not Henrik's boat but another homebuild trimaran 'Kapten Treben'. Skipper is Bertil Hunyadi. It was not glorius race for multis because at start time there was not wind at all. After half an hour wind wake up from back and monos cathc up multi fleet and after that it was "restart" - suigeri Henrik, did this boat just do the Round Lidingö Race? I was not there but the preliminary results list shows a one-off trimaran that caught my eye. /Martin Link to post Share on other sites
Louis Stamos 0 Posted May 16, 2011 Share Posted May 16, 2011 I am curious, the drawings show a tension cord below the crossbeams (for triangulation), sort of like a dolfin striker on a catamaran. What is this corde made of? Does it stay out of the water all the time? Or only touches the tops of big waves? Link to post Share on other sites
