It would be good to talk to someone like Peter Cogan, although designers may not want to give away too many pearls. If you are good with glass I have another option. My 2007 Flyer II (German Built) was damaged while on the trailer by a car crossing the center line. Damage to one hull, but if you are good with you hands you could bring it back to good a lot easier than building from scratch. Just north of Portland, Oregon.
