This is accomplished in three ways. The hull is hand-laid fiberglass and polyester resin in a female mold. A box-beam grid of the same shape is constructed separately. All the wiring conduits, plumbing, and interior furniture are built onto the grid, which is then lowered into the hull. A strong adhesive fuses the two into a single piece. Then the deck is popped from its mold and laid upon the hull. The two lips, or flanges, are joined with 5200 adhesive and fastened with stainless-steel bolts every 8 inches.
