PROBLEM TO BE SOLVED: To provide a bubble float capable of building bubbles not being crushed until a ship overpasses, enwrapping the ship uniformly, and allowing the ship bottom to get on the bubbles like surfing without causing the bubbles to run away. SOLUTION: The configuration of the ship bottom is made in optimum form to run at an economical speed using to a watercourse experiment. Usually the screw of a ship is mostly installed near the stern, but this is installed at the bow and worked, which causes fine bubbles to cover the ship bottom with the screw rotation, so that the water resistance lessens and the ship speed becomes higher to assure a better efficiency. If the exhaust pipe of the engine is positioned in front of the screw, the exhaust gas is stirred to produce more bubbles, and finer bubbles are obtained more effective for decreasing the water resistance. The invention applies to provide a ship power mechanism equipped with such a propulsive force constitution as described above. COPYRIGHT: (C)2006,JPO&NCIPI
