Abstract

A personal watercraft comprises a body including a hull and a deck; a joining section including a horizontal portion protruding horizontally from the body, and a vertical portion protruding downward from an outer end portion of the horizontal portion, the joining section joining the hull to the deck; and a stabilizer mounted to the joining section. The joining section includes right and left joining sections, and a stern joining section. The stabilizer is mounted to a rear portion of at least one of the right and left joining sections. The stabilizer has an inclined bottom surface which is located below a bottom surface of the horizontal portion and extends in a forward and rearward direction such that the inclined bottom surface is inclined in a downward direction as the inclined bottom surface extends in a rearward direction.

First claim

The invention claimed is:

1. A personal watercraft comprising:
a body including a hull and a deck;
a joining section including a horizontal portion protruding horizontally from the body, and a vertical portion protruding downward from an outer end portion of the horizontal portion, the joining section extending to surround an entire periphery of the body to join the hull to the deck; and
a stabilizer mounted to the joining section,
wherein the joining section includes right and left joining sections extending in a forward and rearward direction at a right part and a left part of the body, respectively, and a stern joining section extending in a rightward and leftward direction at a stern of the body,
wherein the stabilizer is mounted to a rear portion of at least one of the right and left joining sections,
wherein the stabilizer has an inclined bottom surface which is located below a bottom surface of the horizontal portion and extends in the forward and rearward direction in such a manner that the inclined bottom surface is inclined in a downward direction as the inclined bottom surface extends in a rearward direction, and
wherein a virtual bottom surface formed by virtually extending the inclined bottom surface in the rearward direction extends through a region which is below the stern joining section.

2. A personal watercraft comprising:
a body including a hull and a deck;
a joining section including a horizontal portion protruding horizontally from the body, and a vertical portion protruding downward from an outer end portion of the horizontal portion, the joining section extending to surround an entire periphery of the body to join the hull to the deck; and
a stabilizer mounted to the joining section,
wherein the joining section includes right and left joining sections extending in a forward and rearward direction at a right part and a left part of the body, respectively, and a stern joining section extending in a rightward and leftward direction at a stern of the body,
wherein the stabilizer is mounted to a rear portion of at least one of the right and left joining sections,
wherein the stabilizer has an inclined bottom surface which is located below a bottom surface of the horizontal portion and extends in the forward and rearward direction in such a manner that the inclined bottom surface is inclined in a downward direction as the inclined bottom surface extends in a rearward direction, and
wherein a rear end portion of the inclined bottom surface is located below the stern joining section.

3. A personal watercraft comprising:
a body including a hull and a deck;
a joining section including a horizontal portion protruding horizontally from the body, and a vertical portion protruding downward from an outer end portion of the horizontal portion, the joining section extending to surround an entire periphery of the body to join the hull to the deck; and
a stabilizer mounted to the joining section,
wherein the joining section includes right and left joining sections extending in a forward and rearward direction at a right part and a left part of the body, respectively, and a stern joining section extending in a rightward and leftward direction at a stern of the body,
wherein the stabilizer is mounted to a rear portion of at least one of the right and left joining sections,
wherein the stabilizer has an inclined bottom surface which is located below a bottom surface of the horizontal portion and extends in the forward and rearward direction in such a manner that the inclined bottom surface is inclined in a downward direction as the inclined bottom surface extends in a rearward direction, and
wherein the stabilizer includes an outer side surface extending in the forward and rearward direction at a right or left outer edge of the inclined bottom surface, a rear end portion of the outer side surface is located below the inclined bottom surface, and an amount of a protruding portion of the outer side surface which protrudes downward from the inclined bottom surface is increased in the rearward direction.

4. The personal watercraft according to claim 3 ,
wherein the stabilizer includes an outer side wall having the outer side surface and protruding downward from the inclined bottom surface, and the protruding portion protrudes inward in the rightward and leftward direction, from an inner side surface of the outer side wall, the inner side surface being on an opposite side of the outer side surface.
