The steering wheel 7 is located on the central step 10, and the occupant stands on the step 10 to grip the steering wheel 7, thereby supporting the body and steering. Further, a fuel tank 13 is installed in a portion of the bow that is a dead space below the steering device. That is, a front casing projecting above the floor deck is formed at the front of the hull, and the fuel tank 13 is installed inside the front casing.

The support 2 is a bifurcated strut 21 and a central tube connected to it.
A connecting plate 22 that connects the support columns 21 to each other is attached to the tip of the central tube 20. The tip end of the column 21 is connected to the connecting portion 25 attached to the hull 1 and is configured to be rotatable around a pin in the width direction of the hull 1, whereby the steering handle 7 uses the connecting portion 25 as a fulcrum. It is configured to swing up and down. An appropriate spring is attached to the tip of the column 21 so that the steering handle 7 is held at a predetermined position shown in FIG.

A steering drum 3 is arranged on the front surface of the connecting plate 22, and a steering cable 4 composed of a pair of outer tubes and an inner cable inserted through the outer tube is connected to the steering drum 3. It reaches the stern through and is connected to the water exhaust nozzle 6. The steering drum 3 is rotated together with the steering rod 70 by operating the steering handle 7, and the steering cable 4 is operated. The piping from the fuel tank 13 and the operating wiring to the engine 90 are also led from the bow section to the stern section through the lower side of the step 10.

In the above structure, the occupant rides on the step 10 and grasps the steering wheel 7 to start the engine to sail on the water. Then, the steering handle 7 is moved to the steering rod.
When it is rotated around 70, the steering drum 3 is also rotated, and the water exhaust nozzle 6 is swung around the shaft 60 via the steering cable 4 connected to the steering drum 3, whereby the water flow is discharged in a predetermined direction and the boat is rotated. Turn body 1. At the time of this turning, the occupant needs to tilt the body together with the hull 1, and at this time, the occupant operates the steering wheel 7
You can support your body by grasping. That is,
Since the steering wheel 7 can only rotate around the steering rod 70 and does not move otherwise, it can support the body by grasping the steering wheel 7, and by rotating the steering wheel 7 in that state. Steering can be performed.

Also, when turning, the occupant supports his weight by placing his one foot on the downward slope of the rear face of the front casing, or by supporting his weight on one step 99 of the rear casing to stabilize his body and back and forth. You can change your driving posture by leaning to the left or right.
