A buoyant boat with a girder box is provided. The girder box maintains the deck part and hull part of the boat in predetermined spaced apart relation and allows the transmission of forces and stresses along the length of the boat. The girder box further enables an outboard engine or an inboard engine in the form of a propeller or hydrojet to be provided. A relatively resilient buoyancy part is provided in accordance with the structure of the invention which extends peripherally of the hull and deck parts to advantageously prevent entry of water into the boat while providing the advantages of design variability, stability and puncture resistance over inflatable structures.

A boat having a hull and comprising: a hull part disposed generally at and below the water level of the hull; a deck part extending longitudinally at least a substantial portion of the length of the hull part and transversely at least a substantial portion of the width of the hull part; a girder box means provided along the longitudinal axis of the boat and mounted between said deck part and said hull part, said girder box means having first and second longitudinally extending side walls, said side walls extending longitudinally along at least a substantial portion of the length of the hull portion, said side walls being laterally spaced from an outer peripheral edge of said hull part and from an outer peripheral edge of said deck part; and a topside part disposed generally at and above the water level of the hull, said topside part defining ar relatively resilient buoyancy part for minimizing fluid entry into said boat; a peripheral edge of said deck part being laterally spaced from a peripheral edge of said hull part to define a gap therebetween along at least a substantial portion of said peripheral edges, said buoyancy part being disposed in said gap between said hull and deck parts and being at least one of mechanically and adhesively secured to each of said hull and deck parts.
