Here is what the plan looks like:

In the book "The Boat Repair Manual" by Buchanan, he shows a strip of 
polyurethane foam between the bulkhead and the hull along with a triangle 
shaped piece of cardboard in the corner between the hull and bulkhead. Then a 
couple of layers of fiberglass over that. He says that:

"This ensures that in the event of a severe localized impact the hull is 
supported by ther flanges, and not by the ridged bulkhead. It does not 
however, inhibit the primary function of the bulkhead, which is to maintain 
the strength and symmetry of the hull."

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. Sounds like it may even be into the area of overkill. I 
like overkill. The 3M 5200 looks like some real good stuff for this 
application. 

The bulkhead will be 6mm okoume marine plywood sealed up fiberglass 
on either side and epoxy.

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.
