The chain plate must have been leaking for several years because the bulkhead that it is attached to is rotted. Has anyone attempted to replace the port side bulkhead. It is attached with a 3" fiberglass flange on the hull. does any one know how far it goes down below the bunk or the floor and if it is attahed there? How about at the ceiling? Anyone know how it is attahced there? Finally, how is it possible that this simple piece of 1/2 inch plywood is strong enough to hold the chain plate? Help! saberlin@yahoo.com
