It can be tricky to fit an entire one piece replacement bulkhead, but it would certainly make for the best possible repair. The problem with through-deck chainplates secured to a bulkhead is that there is often water
intrusion, and this is bad news for plywood
. So, whether you do the entire bulkhead or just a piece, I suggest a layer of mat and one of cloth, and cheap
polyester resin over the piece, especially the edges. When securing a bolt through the piece to attach the chain plate
, drill the hole way oversize, fill with resin and some wadded up scrap of matting, and then drill through this fiberglass
potting. Oversize replacement chainplate and backing plate, with extra bolt holes, is a good thing. Also take a good look at where the chainplate passes through the deck
, and do what you can to prevent water
intrusion. I should say, moisture intrusion. It usually isn't a steady dribble... more like a seep.
You might also consider moving the chainplate to the hull
itself, with proper reinforcement and backing. I have done this a time or two. Sometimes it is the best way out of a dilemna.
While you are messing with this project
, carefully inspect your chainplate for crevice corrosion
. These things do fail, sometimes.
