This sounds reasonable - originally, I was thinking that you were just referring to foam and sealant without the fiberglass. > If I use 3M 5200 Marine Adhesive Sealant in place of the polyurethane foam, > put a triangle piece of foam in the bulkhead - hull corner and tie it all > together with 4" fiberglass tape, that would give me a very strong and yet > flexable connection.

Are you using fiberglass tape on both sides of the bulkhead? If so, I'd skip the 5200 and just use foam. The 5200 would take a while to fully cure and sealing it into the fiberglass may delay its full cure. The fiberglass will provide all the seal you'd want. Instead of a triangle of foam. I'd consider a trapezoid of foam with the wide base against the hull and narrow side against the bulkhead with one strip of fiberglass on either side. The foam would shape the fillet on both sides. If you're using tape on one side only, the sealant is a good idea. Get the fast cure version though. > The bulkhead will be 6mm okoume marine plywood sealed up fiberglass > on either side and epoxy. I used 4mm okoume for a bulkhead (and shelf) in my Solstice with glass on both sides (6 oz) and found it plenty strong - 6mm sounds like it might be overkill. 6mm will certainly handle a footpump. > I am new to all this fiberglass/boat repair stuff so I am asking lots of > questions along with some reading. Thanks for your support Get your hands dirty (well, figuratively speaking - wear protective gloves against the epoxy!) and you'll learn fast enough.
