Abstract

PURPOSE: To make the navigation on shallow water feasible by revolving the propeller of the boat at high speed exposing a part of the said propeller over the surface of the water, thereby decreasing fuel cost and preventing caviation.
CONSTITUTION: Power is transmitted to the power shaft 6 to revolve the propeller 7. As revolution of the propeller 7 increases, the speed of the boat is increased, and as the boat starts siliding the draft of the ship and her propulsive equipment become shallow. Hence, the propulsive equipment and a part of the propeller 7 come out over the surface of the water. At this moment, vacuum inside of the vacuum pressure cover 3 is high, and if air is supplied inside of the vacuum pressure cover 3 by opening the air control valve 5 the water level in the vacuum pressure cover 3 goes down the amount of water paddled by the propeller 7 greatly decreases, and number of revolution of the propeller 7 goes up. The water paddled by the propeller 7 files asunder abaft the boat at a high speed and the boat navigates at a high speed.
