[quote=rch701]well. a pontoon wieghs roughly 200lbs and i am 165 my gf is 130ish. the torque from the sails will equal that unless we are flipping. the faster the boat goes the less torque there will be. after figuring the wieghts you have to find there independent center of gravities and then do a wieghed average to find the absolute CG. after that you do the reverse to find what the centerboard and rudder must hold. i think that i will make a foil for the front of the pontoons to lift them up. the foil will have the slipping load on it. i do not think that the 1980 centerboard well and my delaminating stern will stand up to the abuse. also the force on the boards is just in the vertical axis. the torque on the wells would be close to normal. since the rudders have wieght on them i can trim to boat to stay relativly level(depends on crew postion). nose diving could be fixed with the standard skii on the bow but i want to see if it does it first.[/quote]
