There are three 5.2s at my club that are not used. I am SURE there are spare parts at the owners homes. The hulls and tramps may or may not be salvagable - but the beams, masts, boards, rudders, sails, and other hardware may be of some use. Trailers are probably ok after replacing tires.

Or you may could buy them really, really cheap. I'll be glad to hook you up with the owners.
