<p>To increase propulsion efficiency and on board ship comfort performance, wherein the hull (10) creates a wave rising at a distance behind a transom (13) of the hull (10), and a screw propeller (20) is mounted rotatably to the hull (10) at a distance from the transom (13) and preferably at a level such that the propeller (20) will be submerged under the crest (41) of the wave when propelling the ship at cruising speed, to enable use of a propeller (20) having a large diameter (D1).The ship may be a single screw propeller ship, a twin screw ship, or a multi propulsive ship.</p> |
