Distance between mast and centerboard
I have many times been wondering how the distance between mast and centerboard is actually calculated for a well balanced boat. We have had many threads with discussion about changes to the rig, latest in the OozeGoose thread and this is a knowledge I think would be useful.
I guess in some way you need to pick an average sheeting angle. What angle is usually used? The more a sail is sheeted out, the more forward the force will be, the more it is sheeted in, the more aft it will be. Or?
