ABSTRACT:
A powered planing catamaran has a pair of asymmetric V-bottom hulls such that the inner surfaces of each of the hulls defines less of a deadrise angle than the outer surfaces. The inner surfaces define the primary running and planing surfaces. The bridging structure that connects the hulls defines an inverted tunnel-like channel that is broader at the bow end of the boat than the aft end and which defines an essentially inverted U-shaped configuration from amidships aft. A V-shaped nacelle is formed at the bow end of the underside of the bridging structure and is configured to dampen the slamming effect of waves at low speeds. At planing speeds, the nacelle is out of the water.
