ABSTRACT:
The invention is a molding process for forming a hull for a catamaran which has a sidewall that includes a first layer of fiberglass and polyester resin forming its exterior surface and a second layer of fiberglass and polyester resin forming its interior surface which is mechanically coupled to the first layer to form a structurally strong member. The hull includes a first member which forms the first portion of the hull, a second member which forms the second portion of the hull and a third member. The first member has a band adjacent to its peripheral edge that is indented to form a ledge. The second member has its first layer of the sidewall bent inwardly a slight amount adjacent to its peripheral edge in order that it may rest on the ledge of the first member and its second layer of the sidewall also adapted to rest on the ledge of the first member. The third member which is mechanically coupled to the second member adjacent to the bent peripheral edge on the interior surface of the sidewall and which is adapted to be mechanically coupled to the interior surface of the first member by glue secures the first member to the second member.
