How about developing a cross breed of the hard wing and soft sail, sort of like an inflatable ribed wing shaped sail or one with more battens that would hold camber in both directions at once, thus making a "wing" type sail out of mylar type sailcloth, that could easily be taken down and stored every night. I picture like the wing of an ultra light aircraft that uses battens in dacron cloth with a tube spar at the leading edge. Has anyone ever tried that? You could use the same hulls and use the cheaper, easier wing for practice, then use the real expensive wing only for the actual regattas. That way you could all race as a fleet with the cheap set up before you blow all your dough on the real wing.
