ABSTRACT:
A rigid hull inflatable style boat constructed of rigid-shell modules. Modular gunwale sections are mounted to the trailing ends of a modular bow section to form the a flotation collar. Boats having greater/shorter lengths can be constructed by increasing or decreasing the number of gunwale modules. The bow and gunwale modules may be formed of molded polyethylene filled with hydrophobic foam material. The floor/hull module can be mounted at varying heights within the flotation collar to alter the performance characteristics of the craft. The hull module may have a V-shaped hydrodynamic contour, so that when the hull module is mounted relatively high within the collar the boat has a sponson-type hull form, and when the hull module is mounted relatively low within the flotation collar the boat has a V-type hull configuration. The flotation modules have a generally D-shaped configuration, with flat, vertically extending inboard walls that mate with a vertically-extending flange on the floor/hull module so that the latter can be adjusted to a higher or lower position within the collar during assembly.
