The tail bar 130 is moved in the stern direction by the rotation of the furnace boss 120. The wing portion 140 is hingedly coupled to the third portion 133 while maintaining the predetermined angle with respect to the third portion 133 and pushes the fluid while keeping the same angle by the pressure of the fluid even while the tail bar 130 is moving The hull 110 moves.

Thereafter, when the occupant pushes the grip portion 123 gripped by the occupant, the extension portion 122b and the engaging portion 122a pivot toward the front side about the long shaft 121 as the center. When the furnace boss 120 rotates, the tail bar 130 moves in the head direction. At this time, the wing portion 140 forms an equilibrium with the third portion 133 by the pressure of the fluid in the process of moving in the head direction, and is finally recovered while moving along the water surface. Therefore, since fluid pressure is not received, the fluid resistance is recovered in a minimized state.

Meanwhile, when it is desired to change the direction of the hull 110 in the process of advancing the hull 110 through the above-described operation, the passenger rotates the foot unit 161 with the foot fixed around the shaft 161a. When the footrest portion 161 rotates, the directional key 162 connected to the transmission portion 163 and the transmission portion 163 linked thereto is rotated.
