http://www.trawlerforum.com/forums/s...raft-6833.html Look through this post to get an idea of what refastening might look like. We are now at $30,000 in silicon bronze fasteners. This project is going to cost close to $90,000. I have seen $140,000 spent on refastening on 50ft wooden boats. Refastening is generally replacing, adding to existing screws that have failed due to electrolysis. The screws fail as the zink leaves the bronze leaving a very week porous copper screw that crumbles on removal. The wood adjacent to the screws is damaged as well so you generally have to replace with larger longer screws. Stainless is not an excepted alternative as an under water fastener in wood.
