Abstract
In a personal watercraft and a buffer member of the present invention, a gunnel or the buffer member (bumper) functions as a sponson. An elongate-plate shaped sponson portion is protruded in a lower portion of a corner bumper provided on a side portion of a body along the longitudinal direction of the body. The sponson portion extends such that its longitudinal direction substantially corresponds with the longitudinal direction of the body. A rear end portion of the sponson portion has a width larger than that of a front end portion thereof. The corner bumper functions as the sponson as well as the conventional buffer member.
Claims8
A water-jet propulsion personal watercraft comprising:
- a body formed by a hull arid a deck covering the hull from above, the body having a gunnel formed by a joint portion joining the hull and the deck over an entire periphery thereof and configured to protrude outwardly from a side wall of the hull, and a space inside thereof configured to accommodate an engine for the watercraft;
- and
- a single-piece buffer member mounted on the gunnel at a rear portion of a side portion of the body, wherein
- the single-piece buffer member has a protection portion covering at least an outer portion of the gunnel, to protect the gunnel and a plate-shaped extension portion extending downwardly from the protection portion by a predetermined length from a lower end of the gunnel and by a predetermined length in a longitudinal direction of the body such that the extension portion is spaced a predetermined distance apart from the side wall of the hull below the gunnel.
A water-jet propulsion personal watercraft, comprising:
- a body formed by a hull and a deck covering the hull from above, the body having a gunnel formed by a joint portion joining the hull and the deck over an entire periphery thereof and configured to protrude outwardly from a side wall of the hull, and a space inside thereof configured to accommodate an engine for the watercraft, wherein
- the gunnel is formed by joining a hull protruding portion extending outwardly from the side wall of the hull, and a deck protruding portion extending outwardly from a side wall of the deck, the deck protruding portion being configured to cover the hull protruding portion from above, and
- the gunnel is provided with a plate-shaped extension portion formed on a rear portion of the gunnel to extend downwardly from the gunnel so as to be spaced apart a predetermined distance from the side wall of the hull below the gunnel, the extension portion extending by a predetermined length in a longitudinal direction of the body.
A buffer member for a watercraft having a body formed by a hull and a deck covering the hull from above, the body having a gunnel formed by a joint portion joining the hull and the deck over an entire periphery thereof and configured to protrude outwardly from a side wall of the hull, the buffer member comprising:
- an elongate protection portion configured to partially cover the gunnel to protect the gunnel;
- a groove portion provided in the elongate protection portion to extend in a longitudinal direction of the elongate protection portion, the groove portion being externally fitted to the gunnel to allow the elongate protection portion to be removably attachable to the gunnel;
- and
- an elongate-plate shaped portion protruded downwardly from the elongate protection portion such that a longitudinal direction of the elongate-plate shaped portion substantially corresponds with the longitudinal direction of the elongate protection portion;
- wherein the elongate protection portion has a hole into which an attaching bolt is inserted to allow the elongate protection portion to be removably attached to the gunnel;
- and
- wherein the elongate-plate shaped portion has a vertical dimension increasing from one end portion toward the other end portion in a longitudinal direction thereof.
