Erase all this. Lift from the foil replaces part of hull flotation at speed, so righting moment drops with speed simply because the foil's center of lift is more inboard (closer to the mast) than the float.

This may be a dumb question, but why not have the boards bend the other way (i.e. the tip extending outboard when down)? In other classes there's a max width, but that shouldn't be a problem here.
