ABSTRACT:
A boat comprising a tube-like hull (1), a hydrofoil (2) fixed to its front portion, a pair of wings (4) hinged to each side of its rear portion, a fin (20) fixed to its rear bottom portion, an out-board-type motor (9) provided in its center of gravity, and a steering lever (14) that can be rotated and also tilted. Rotation of the lever (14) causing rotation of the motor (9) and steering the boat. Tilting the lever causing lifting or lowering the wings (4). Each wing (4) has a float (5) fixed to its end. When the boat stops and at low speed the floats are in the water. When the boat at high speed an operator gives lift to the floats out of the water. At highest speed an operator puts the wings in parallel with the water surface and a ground effect is used. Central location of the motor contributes the boat to go into hydroplaning at low speed and gives lift to the rear portion of the boat using water pressure created by a propeller. The most controlable boating and efficient usage of motor power are provided.
