Interesting...so it has already been done in a primitive way...I was thinking if you could make the hulls pivot at the beam attachment points so that the leeward hull could stay flat on the water as the windward hull left the water. It would make it a lot faster...seems from the video that he is cooking along nicely until the leeward hull goes from flat to angled, which is no surprise since the fastest way to sail a sailboard is keeping the hull flat as possible. Now if you could some how steer the craft with modified sailboard fin and get rid of the rudder and centerboard it would be even better/faster. It is a huge rush to be going 30-40 mph on a sailboard standing up…if you could approach those speeds sitting down, with the water so close….it would be unreal.

Michael why use plywood?...Why not make it out of Styrofoam/Divinicell/epoxy just like windsurfers? You won’t be limited by the bending ability of the materials and it will be super light. A 9’ slalom board is sub 15 lbs. As long as you are not going to have too much hull volume it would be a viable alternative.

Might have to form another forum heading for cats 12’ and under…LOL
