A cavitation reduction for the high speed of vessels is provided to enhance the pressure by filling the low pressure area of the vacuum condition with the water with a pump in order to reduce the cavitation. A cavitation reduction device for the high speed of vessels comprises: water pipes(1,5) installed in a propeller central part of vessels in order to supply the water to a cavity generated with the high-speed propeller rotation; and an electric motor pump(3) controlling the amount of the water in an water supply pipe according to the speed of engine by connecting to a rotary shaft of the engine. The water supply pipe is submerged in the water by directly supplying the water to low pressure areas(2,5) generated with cavity. The speed enhanced in a first shift can be accelerated in a second shift to twice by serially connecting a device including two propellers. |
