ABSTRACT:
A catamaran air cushion water vehicle has two spaced apart floats (111) which extend parallel to one another in the direction of travel, wherein the cross-sections of the floats become broader from the bottom to the top and wherein the floats are rigidly connected together at the top by a deck structure (113). Furthermore, resilient skirts (123, 124) are arranged up to the stem and at the stern between the floats (111), extend at least approximately down to the water surface, and, together with the floats (111), bound an air space (125) between the base of the deck structure and water surface. In accordance with the present teaching the floats (111) each have a hull section (112) which broadens out in step-like manner essentially above their float region (115) which is submerged during travel in the displacement mode. The hull sections (112) serve to accommodate machinery, such as the propulsion units, and the deck structure (113) is attached to the upper end regions of the hull sections (112).
