  1. i was going to write the same as Mad Hatter... i also thought that you could reuse the one off cut of the hole to stiffen you deck like this (sorry for the rough sketch not to scale)
  2. new trimaran under 20" on sailing anarchy
  3. I haven't got much pics of the build but you can look at the" new trimaran under 20" thread for photos My motto in boat building:don't pray the Lord, spray the load Please put pics of your build as it goes as I don't facebook
  4. looking at your last drawings, if you estimate the total load is 200kg vertical it will be 170kg on each side with the 90° angle. is that a big improvement? and the total load on your mast will be 14 x 80 kg= 1040 kg on the mast at 25 kn wind You should at least double that number for safety reason. we are not even talking of that time when you will drop speed from 20kn to almost nothing when falling from foiling.... Epoxy-Carbon a 100 mm high layer of foam or plywood on the edge as Mad Hatter told you and go for a center chainplate for the jib. you could go for another place to hold the mast at the front of hull with a hole with carbon also. look at the photos for the ring fitting (thank you VMG) and for the hole to hold the mast all these things could be done quite quickly if you go for it and good on you for that project
  5. look at ropeye chain plate or carbon a big ring in the center with a stringer underneath would be cheaper easier stronger i would think

    hello Patzefran and every one 2 square is on a boy in the golfe du morbihan and i have been out 4 times for the last 2 weeks. today was best with 16 kn up to 23. my wife and I did a coville planté ; she got a bit scared but all was fine: 2 square put itself up again on its own . still no video or photo but soon I will get an droite phone with sailfreegps apps so I will be able to report on speed and other things. help to improve? and well done french do it better (by the way i am not so sure that 's true, being an ex OZ boy) hope to see you soon around Arradon for a ride ...

    thank you tom now i understand it better. I don't think i will use this set up despite it being quite interesting the traveler does not need to be more than1,5 mt altogether . i never had to let the main going further than that the two mainsheet seems a little bit complicated to operate but it might a question of being use to it the load on the boom will be to much( it is only a reinforce all carbon windsurfer mast or though i could add some more carbon anyway you give me to think about it good on you

    i do not understand what you mean Tom Here is a foto of the bridle and blocks the traveler are not on but go from the bottom bock to the little red cleat.the problem is the length of the bridle where the bottom block glides It is to long 2 meters and the boom to low. I might go for a rail because i did not save any weight there is 2 more blocks on the big bottom one for the traveler and 4 more to adjust the tension of the bridle to the side of the main hull (previous foto) can you tell me more about what you think()i will answer tomorrow ) block

    there is a traveler but no rail. i am using a DM 20 max bridle (like a Laser) and and 2:1 sheave for the traveler but it is not working as well as it's supposed to be: i find it really hard to tension the bridle as i want without putting too much load on the main hull because there is only 45 cm between the bome and the bridle and i have a 8:1 57 harken carbo for the main sheet

    no but surely 6 months between designing ,time for "how am i going to to this", finding bits and pieces at the local gumtree or craiglist ( le bon coin for us) and sanding,sanding,sanding... 80 x 4 mmCarbon tube reinforced with 1kg ud carbon top and bottom for the front ones 180 x 74 x 2mm carbon mast of which i cut the gooseneck, add a flange (foam +ud carbon) in the middle , closed it and same as above main hull is 4mm plywood with 300g biaxial glass both sides + ud carbon where it needs floats are Hobby miracle 20 heavily modified( wider, higher minus 13 kg for each of them) all carbon work is vacuum bagged Hello patzefran you are right what i meant was just main hull just kissing . the first time was supposed to be 8-10 KN. in fact 10-15 then 15 to 20, and i called it a day at 16h when the golfe du Morbihan was more white than blue. we never had to be on the trampolines but we were both of us really back the second time 10-15kn and i do feel she is under powered because everything is so easy and not physical. I am thinking of adding 1,5 mt to the mast so it will be around 28 m2 about the stiffness , the problem was longitudinal with only 2mt between the 2 arms so i decided to go split shrouds with 8:1 at the front .this is lifting the amas about 25mm each side and it is very very stiff. Thank you all for your comments , i really do appreciate with no false modesty

    the TOTAL rigged weight is 300 KG with DM20 max rigging the amas are around 875 lts so about 300% i don't have any video yet and I am currently building the bowspirit so not to soon

    Hi Tom you are right i should be using a self tacking jib but I wanted to be sure of the balance of the overall design : There is 2 daggerboards on the amas as well and i wasn't sure of their positioning /Sail plan and yes i think she is flying 1 hull because of the "vvvvvvvvv" i can hear suddenly when she kicks off good luck with your sea rail as soon as you get back your sail you are right
