Abstract

A personal watercraft comprises a body including a deck and a hull, the hull includes a bottom surface facing downward and side surfaces facing outward in a rightward and leftward direction, the bottom surface has a shape in which a width in the rightward and leftward direction is reduced from its center portion in a forward and rearward direction to its rear portion, in a center portion of the hull in a forward and rearward direction, each of the side surfaces includes an upper side surface and a lower side surface, the lower side surface and the bottom surface are connected to each other to form an obtuse angle in a cross-section viewed from a rear, and an inclination angle formed between the lower side surface and a vertical line is set to be greater than an inclination angle formed between the upper side surface and the vertical line.

First claim

The invention claimed is:

1. A personal watercraft comprising:
a body including a deck and a hull,
wherein the hull includes a bottom surface facing downward and side surfaces facing outward in a rightward and leftward direction,
wherein the bottom surface of the hull has a shape in which a width in the rightward and leftward direction is reduced from a center portion of the bottom surface in a forward and rearward direction to a rear portion of the bottom surface,
wherein in a center portion of the hull in the forward and rearward direction, each of the side surfaces includes an upper side surface and a lower side surface located between the upper side surface and the bottom surface, and
wherein the lower side surface and the bottom surface are connected to each other to form an obtuse angle between the lower side surface and the bottom surface in a cross-section viewed from a rear, and an inclination angle formed between the lower side surface and a vertical line is set to be greater than an inclination angle formed between the upper side surface and the vertical line.

2. The personal watercraft according to claim 1 ,
wherein a vertical length of the lower side surface of each of the side surfaces is set to be shorter than a vertical length of the upper side surface of each of the side surfaces.

3. The personal watercraft according to claim 1 ,
wherein a boundary between the upper side surface of each of the side surfaces and the lower side surface of each of the side surfaces extends rearward and upward.

4. The personal watercraft according to claim 1 ,
wherein the bottom surface of the hull includes a pair of guide groove surfaces which extend from the center portion of the bottom surface toward a rear end of the bottom surface, and are recessed in an upward direction, in the cross-section viewed from the rear, and
wherein the bottom surface includes a pair of lateral end bottom surfaces, each of which is provided between the lower side surface and the guide groove surface.

5. The personal watercraft according to claim 1 ,
wherein the rear portion of the bottom surface has a width in the rightward and leftward direction that is 90% or less of a maximum value of the width in the rightward and leftward direction of the bottom surface.
