[snip] > Dave, first take a look at Ferenc Mates' book "From a Bare Hull" (1983 Albatross pubs.) where he gets into strengthening fiberglass decks in yachts in some detail. He uses closed cell ureathane foam shaped like a squared or trapazoid (?) beam, contact glued to the underside, then a couple layers of cloth laid up over it and tapered. The foam obviously doesn't give any stiffness or rigidity (maybe some flotation?) but it's the shape of the "beam" that does the stiffening. Those beams probably wouldn't have to be any more than 1.5" x 3.4" so you wouldn't be losing much room in the bulkhead. Think about the top of a wooden acoustic guitar. Those tops are about 7/64" thick and even if you tripled the thickness, you'd still not get the ridigity of thin the fan bracing inside the guitar.
