ABSTRACT:
The invention is a molding process for forming a reinforced hull for a catamaran which has a first member which forms the first portion of the hull and which has a band adjacent to its peripheral edge that is indented to form a ledge and a second member which forms the second portion of the hull and which has its sidewall bent inwardly a slight amount adjacent to its peripheral edge in order that it may rest on the ledge. The reinforced hull has a sidewall which includes a first layer of fiberglass and polyester resin which forms the exterior surface of the sidewall for both the first member and the second member and a second layer of fiberglass and polyester resin which forms the interior surface of the sidewall. The second layer has a plurality of substantially parallel ribs running longitudinally along the hull with the ribs being formed from the second layer. The first layer is chemically joined to the second layer. The first and second members are joined together and glue is placed between the first and second member into the rib adjacent to the peripheral edge of the sidewall of the first member.
