Foamboat construction

Step 10 Real deal, P05

P01 served its purpose to proof the FOAMBOAT concept, develop tools and working techniques, and to show that a mold built in this way is extremely strong and stiff because of the very thin pieces of plywood encapsulated within it at 90 degree angles to one another. A crust of fiberglass and epoxy would add even more strength. P01 turned out much bigger and heavier that I wanted for my original purpose, so I did not even fiberglass it. I realized I did not need the 1/2" thick plywood deck board for strength, which made up half the weight of the mold. The next hull I constructed was the streamlined P05, and I used the same thin marine plywood for the deck plate that I used for the other wood pieces. I glued four blocks of 3/4" plywood to the inside side of the deck plate, at two locations where I could screw through the deck of the finished fiberglassed hull and into the blocks to make attachments. I marked the locations of the blocks on the outside side of the deck, which could be seen through the deck's layer of fiberglass.
