Im seeking advice regarding structural integrity of the forward main bulkhead. Yes, this is the one that the chainplates attach to.
A design/construction problem 25 years ago, has manifested it's ugly head. Water, as it would come down the mast via halyards, etc., would be funneled to the forward side of this bulkhead where it would pool and slowly cause the rot that I've detailed in the included sketch and photos.
This bulkhead was glassed to the aft side of a main stringer.
My questions are the following:
1. Has the bulkhead integrity and hull stiffness been compromised?
2. Would new teak marine ply glassed back into the area with butt joints just above the bottom of the doorway passage be strong enough?
3. In conjunction w/Teak marine ply, would adding 1/4" alum plate as indicated on the drawing, that is scarfed over good solid existing bulkhead sufficiently re-enforce the bulkhead?
I'm thinking I'd drill 1/8" random holes and really scuff up the alum plate to enhance bonding. The alum plate would then be cosmetically covered with teak veneer to match existing. Total thickness would not exceed existing bulkhead thickness (about 3/4")
