My 10ft 2 sheet ply Duo dinghy might suit. Sailing Catamarans - Duo 10ft Sail/Row Dinghy (nesting option)...
It should be fairly straight forward. There is lots of design and empirical data for wood and aluminium free standing masts. You need to keep EI...
Pictures don't tell the whole story. We would need to see your hydrostatics before making useful comments. And also the rig/deck layout/buoyancy...
Drawing a lines plan is a spiral, you go round and round. Throw it away and start again, and again. Drawing by hand is much harder as the...
Looks like you are building one of Kurts 30fters. So - what does he say? Always ask the designer first! Richard Woods of Woods Designs...
Its built with 2 sheets 4mm ply, say 15kgs, cannot get much lighter than that and still have seats and built in buoyancy, never mind durability...
Thank you Alan! You can see me carrying my Duo in the first rowing video and on my website. We use ours daily when cruising on our Skoota - we...
I agree, I think its a Solcat 18. But puzzled by the mast length V mainsail luff?? few beach cats have a boom 4ft off the deck. And even a Tornado...
video here [MEDIA] Of course only two rudders, not 4. I have steered a boat with a Viking style rudder/tiller. Designers of fast boats haven't...
The tractors etc I have seen tend to have levers/cables/pipes etc on the outside. Good for maintenance, not good for aesthetics or for building an...
we discussed doing that in Moths about 40 years ago! Richard Woods
Check the Mull designed 12m USA61, the Everitt Backlash etc for forward rudders/canards. Consider how you will control 4 of them so they work...
yes 24hrs is the normal time for average shop conditions, say 15C. But can be shorter, often people gel late afternoon and skin the next morning,...
Looks much better now, a much stiffer platform. maybe its the camera angle, but can you get enough jib leech tension? the track seems a long way...
Of course there is no point having a boat that only sails fast offwind. Unless it can sail well to windward eventually you get trapped on a lee...
You still have a decimal point problem .453Kg is about 1lb you don't use newtons for displacement/buoyancy/weight Seems like you have a steep...
No, mainly because the beams would be huge and thus heavy. The trimaran scores as the individual beams are shorter, even though they carry the...
I am not very good in imperial units but I think 10 million lb total displacement means you have a decimal point in the wrong place. As always,...
In haste. I think bilge keels would probably stabilise the roll better than paravanes, particularly in the St John river (which I know well north...
Patrick in France usually posts on this thread but now its my turn. He just sent me a link to a couple of videos of his home built plywood main...
