Abstract

A substantially U-shaped front bumper as seen in a plan view is mounted on a gunnel at a front end of the watercraft so as to partially cover the gunnel. The front bumper has a base portion attached to the gunnel, and an extending portion extending upwardly from the base portion so as to partially cover a streamlined surface of a deck. The base portion is provided with right and left concave portions extending in the lateral direction of the body. The extending portion is provided with a concave portion extending from one end to the other end in the lateral direction.

Claims (13)

1. A jet-propulsion personal watercraft, comprising:

a body formed by a hull and a deck covering the bull from above, the body having a gunnel formed by a joint portion joining the hull and the deck over an entire periphery thereof;

a water jet pump mounted in the body, for ejecting water rearward to propel the watercraft as a reaction of the ejecting water; and

a buffer member mounted on a front portion of the gunnel so as to cover a front end portion of the body, wherein

the buffer member has a base portion that covers the gunnel and an extending portion extending upwardly from the base portion so as to partially cover an upwardly oriented external surface of a front end portion of the deck.

2. The jet-propulsion personal watercraft according to claim 1 , wherein the extending portion extends upwardly from the base portion with a height increasing from a front end of the body toward a lateral end of the extending portion.

4. The jet-propulsion personal watercraft according to claim 3 , wherein the concave portion is provided in each of the base portion and the extending portion.

5. The jet-propulsion personal watercraft according to claim 3 , wherein the concave portion has a substantially U-shaped cross-section when sectioned along a direction perpendicular to a longitudinal direction of the concave portion.

6. The jet-propulsion personal watercraft according to claim 3 , wherein the concave portion has a depth that increases from the vicinity of the front end of the watercraft toward the lateral end of the buffer member.

7. The jet-propulsion personal watercraft according to claim 3 , wherein the concave portion has a width that increases from the vicinity of the front end of the watercraft toward a rear end of the buffer member.

8. The jet-propulsion personal watercraft according to claim 3 , wherein the concave portion
