Abstract

PURPOSE:To enjoy both surface and underwater sailings with a simple structural device by riding on a diving boat in a way of lying on one's belly, operating a propeller of a floating body or the diving boat and a pump of this floating body, and regulating the buoyance by feeding or exhausting air to or from the inside of the diving boat. CONSTITUTION:A person 10 rides on a diving boat 1 as sprawling on it in the state that he is on a water surface 11, and a floating body 2 is driven by operation of a handle 3, while he operates a rudder 32 via a shaft 31, thus sailing on the water surface 11 takes place. At this time, air is fed into the diving boat 1 by the pump provided in this floating body 2, and buoyance is given to the boat in advance. And, when a cap 70 is opened and air in an air chamber is reduced, the diving boat 1 reduces its buoyance and submerged in the water, therefore the floating body 2 moves along a slide pipe 5 via a joint member, thus it is continuously sailing on the water surface 11. Then, propulsive force is given by a propeller 20 of the floating body 2 or the diving boat 1, thus the diving boat 1 sails in the state that it is submerged at constant depth downward the water surface 11.
