Hi again, Rick, I was discussing building a fiberglass whitewater kayak with a friend (whom incidentally I met on the Building BBS). He is a pretty serious boater, and was considering the same type of construction, but to build a squirt boat. We looked through the link that John Fereira posted regarding the "Gecko". My friend Joe said that instead of leaving the foam in the boat, one could cut around the glassed shell at the sheerline with a jigsaw. Then, the foam can be removed, and the hull and deck re-joined together with glass tape.
You could go for this type of construction, paddle the first prototype, and then you'd still have your mold for making a replacement or spare, or you could model the foam mold further and make improvements to the design.
