PURPOSE:To manufacture a hull, which has a mounting part for an engine and fuel tank and a reinforcement, with less man-hours, through simple processes, and at a low cost, and enhance the dimensional accuracy of the mounting part without use of jig, etc. CONSTITUTION:A preform of reinforcing fibers, a core 35 of a reinforcement 30, and a mounting part 36 for engine and fuel tank are fabricated previously and set in place in a mold for a hull 2, and then a resin is poured into the mold and left hardening, and thereby the reinforcement 30 and the mounting part 31 are constructed in a single piece with the hull 2. |
