Abstract: A modular boat hull including bow and stern sections and at least one center section. Preferably these modular sections are rotomolded thermoplastic parts. These modular hull sections can be quickly assembled by coupling a center section to the bow section and then coupling the stern section to the center section. To increase the length of the hull, additional hull center sections can be added as desired. The modular hull sections are coupled by locking arrangements and then secured by installing a support member which bridges the joints between the gunwale sections of adjacent hull sections. Each modular hull section has a lattice for supporting a deck. The deck can be a single piece installed inside the assembled hull. Alternatively, the deck may be modular.

Abstract: A multilayered fiberglass boat structure is described. The fiberglass boat structure includes a plurality of layers of resin impregnated fiberglass reinforcement and a plurality of layers of a polyester film. Each film layer is formed from a gelcoat, with at least one of the film layers formed from a gelcoat that includes iridescent polyester particles.
