Furthermore, connecting passages 36 and 37 to the rear rear seats 23, 24 and 25, 26 are formed on the outer side of the driver's seat 9 and the passenger seat 10.
Even if the operator or assistant is sitting in
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 water jet 21 are provided with protruding bottom parts 17 and 18 like a catamaran, and the center of the hull body 1 is where the engine 3 and the water jet 21 are, so A protruding bottom portion 19 is formed.

[Effects of the Invention] Since the present invention is constructed as described above, the following effects can be achieved. That is, since the structure is as set forth in claim 1, when the engine 3 is disposed forward of the center of the hull as in the present invention, the center of gravity of the hull moves forward, so that when sailing or stopping, This creates an unbalanced situation where the front goes down and the back goes up. This makes it difficult for the aircraft to shift to a sailing runway state, and also causes the problem of being hit by waves from the front when stopped. However, by configuring the hull body 1 in a semi-trimaran shape as in the present invention, even when no one is sitting in the rear seats 23, 24, 25, and 26, the rear part does not rise significantly, and the cruising state Furthermore, even if the rear part lifts up, the protruding recesses 17 and 18 remain submerged in the water, making it possible to maintain straight-line performance at low speeds. Also, it became easier to secure space for the rear seats 23, 24, 25, and 26 at the rear.

[0013] Furthermore, since the structure is as set forth in claim 2, the engine 3
is placed at the rear, rear seats 23, 24, 25
- Although the protruding part of the engine 3 obstructs the section 26, by placing the engine 3 in the front as in the present invention, the rear seat 23
・The spaces 24, 25, and 26 can be created without any obstacles. Also, with this configuration, the rear seats 23 and
This made it possible to configure 24, 25, and 26 to sit opposite each other on the left and right. Moreover, since the structure is configured as in claim 3, even when there are no passengers in the rear seats, it is possible to increase the weight of the rear part, and the shift of the center of gravity to the front, which occurs when the engine 3 is placed in the front, can be avoided. It can be prevented. Furthermore, since the configuration is as set forth in claim 4, even though the batteries 11, 14 and the fuel tanks 13, 15 are arranged at the rear, these can be placed in the rear seats 23, 24, 25,
By placing it under the floor at the feet of passengers sitting on board 26 or under the seats, it no longer makes the passengers feel cramped while partying. Further, since the structure is configured as in claim 5, the communication passages 36 and 37 can be formed in the side portions of the driver's seat 9 and the passenger seat 10 arranged in the front, so that the rear seats 23 and 37 are arranged as facing seats on the left and right sides.・24・2
By being able to secure a passage to 5/26, we were able to eliminate the impression that the building was narrow and cramped as a whole.
