<p>A high-speed planing catamaran is comprised of hulls, each of which has a canard planing surface (6) well forward of the catamaran's center of gravity and a main planing surface (4) aft of and closer to the center of gravity. At planing speeds, the canard surface (6) leaves a trough (8, 9) in the water which substantially encloses the hull portion aft of the canard surface (6). The main planing surface (4) rides on water between the hulls, but outside the trough (8, 9). The angle of incidence of all surfaces may be adjustable, as may the vertical and lateral positions of each hull's propeller (12).</p> |
