I also have a question regarding the 2 x 4 center stringer. The first 3 or 4 feet have some rot (the end closest the transom) and I've already cut back the fiberglass skin, so I'd like to epoxy coat another piece and replace it. Can I do that for only the first few feet where the wood is rotten and fiberglass over it, overlapping the fiberglass over the remaining glass? Would this destroy the structural integrity of the center stringer? I suspect that most of the center stringer strength is derived from the fiberglass. Has anyone else attempted this repair?
