Passing through seats 6 and 37, it is possible to move to rear seats 23, 24, 25, and 26. Also, rear seats 23, 24, 2
If the hull body 1 is configured so that sufficient buoyancy can be obtained with four people sitting on 5.26, this part needs to be made wide, but if the displacement of this part is too large, the rear If no one is in the seats 23, 24, 25, or 26, the rear part of the vessel will rise, and the angle will be such that the water jet 21 will not be able to exert sufficient propulsive force even when navigating by the water jet 21. . The present invention uses a semi-trimaran shape so that the rear part does not rise too much even when no one is in the rear seats 23, 24, 25, and 26. In order to make the semi-trimaran, a groove-like recess 1a is provided at the rear bottom of the hull body 1.
1a is provided, and the left and right ends of the reverse water jet 21 are provided with protruding bottom parts 17 and 18 like a catamaran, and the center of the hull body 1 is provided with the engine 3 and the water jet 21.
Therefore, the protruding bottom portion 19 is also formed.

FIG. 16 is an exploded perspective view of the supporting portion of the operating cable of the backward bucket A shown in FIG. 4 relative to the hull body 1, and FIG. 17 is a side sectional view thereof. The backward bucket A rotates up and down, and when the backward bucket A retreats upward, the jet flow from the water jet 21 is blown straight backward, which is forward movement, but when the backward bucket A rotates downward. When the water jet 21 is moved to cover the outlet of the water jet 21, the jet stream is redirected forward and travels backward. Furthermore, since the traveling nozzle C itself can be rotated left and right, steering in the left and right directions is also possible. The cable 45 that connects the running nozzle C and the steering handle 5 configured in this way requires a portion that exits from inside the boat to the outside of the boat, and as shown in FIG. 17, the operating cable 45 passes through the hull body 1. It consists of parts that A covered hose 46 is fitted around the operating cable 45, and the covered hose 46 is bent upward into an L shape, and the apex of the L-shaped covered hose 46 is located at the water surface S outside the hull body 1. It extends above.

With this configuration, even if water enters the inside of the penetration joint 47 that penetrates the hull body 1 and the water level rises inside the covered hose 46, the covered hose 46 will not extend above the water level S. Because of this, the structure is such that water does not overflow into the interior of the hull body 1. The through joint 47 is passed through a hole in the hull body 1, and there is a flange 49 on the outside of the boat.The through joint 47 is fixed by tightening the thickness of the hull body 1 between the flange 49 and a tightening nut 48. ing. The internal covered hose 46 of the through joint 47 passes through, and the covered hose 46 is externally fitted onto the inside of the hull 1 of the through joint 47 and extends upward in an L-shape. Further, a cap nut 50 is provided at a portion where the through joint 47 protrudes into the sea, and a C-shaped retaining ring that is engaged with the outer periphery of the operating cable 45 is adhered and fixed to the through joint 47 by the cap nut 50.
