摘要： PURPOSE:To effectively utilize the energy of exhaust gas of a main engine for driving a propeller shaft and economize resources, by using the exhaust gas of the main engine to cause an exhaust gas economizer to generate steam for driving a main electricity generator connected to a turbine. CONSTITUTION:Exhaust gas produced as a result of combustion in a main engine 1 is conducted to an exhaust gas economizer 7 to heat feed water to generate steam. This steam is used to drive a steam turbine 8. A main electricity generator 5 is driven through a shaft 9 by the rotation of the turbine 8. A portion of the rotation of the main engine 3 is transmitted to the main electricity generator 5 through a speed-up gear unit 4 and a differential gear unit 6 to drive the generator. A brake gear in the differential gear unit is connected to a stepless transmission unit 14 through a brake shaft 13. The stepless transmission unit is coupled to a braking motive power recovering electricity generator 16 through a braking electricity generator shaft 15. Power produced by the electricity generators 5, 16 is supplied to a bus 20 for energizing the load in a ship.

摘要： PURPOSE:To raise the propulsion efficiency of a high-speed boat by relieving the movement of the hull during the running period by a method in which a buoyancy-generating submerging part is provided to the lower end of a plate bow projectionally provided to the central front side of the hull, and a wide hull-planing face is formed toward the stern through a flare. CONSTITUTION:A plate bow 1 is provided projectionally to the front end of the hull along the its central line in such a way as to cut water by it. A torpedo- shaped buoyancy-generating submerging material 2 having a length equal to the distance to the central part of the hull is provided to the lower end of the plate bow. A residential section 5 on the deck of the hull is provided in the rear side in such a way as to protect it from great tidal waves, and a flare 4 is formed on the side 3 of the hull. A planing face 6 of a wide width is provided toward the rear half portion of the hull on the downside of the hull, and the floating face center of the hull is formed in the behind portion of 1/3 of the length from the end of the stern 7. The movement of the hull on tidal waves can be relieved during the traveling period, and its propulsion effeciency can be raised greatly.
