PURPOSE:To enhance the thrust efficiency of a ship, by forming the whole living area in an airfoil shape and by making the rear living area rotatable in association with the direction of a wind. CONSTITUTION:A living area in a ship is divided into a front living area 3 and a rear living area 4. The rear living area 4 is regulated to an angular position which is determined in dependence on the direction of a wind. As a result, a lift F is generated as in the case of an air-craft and is used for advancing thrust. |
