Personal watercraft and buffer member for personal watercraft
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.
1. 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.
2. The water-jet propulsion personal watercraft according to claim 1 , wherein the single-piece buffer member is removably attachable to the gunnel.
3. The water-jet propulsion personal watercraft according to claim 2 , wherein
the single-piece buffer member has a groove portion provided in the protection portion to extend in a longitudinal direction of the protection portion, the groove portion being externally fitted to the gunnel to allow the protection portion to be removably attachable to the gunnel; and
the protection portion has a hole, wherein
the single-piece buffer member is attached to the gunnel by attaching a bolt inserted into the hole with the groove portion externally fitted to the gunnel.
4. The water-jet propulsion personal watercraft according to claim 3 wherein the extension portion has a vertical dimension increasing from a fore side toward an aft side of the body.
5. The water-jet propulsion personal watercraft according to claim 1 , wherein the extension portion has a vertical dimension increasing from a fore side toward an aft side of the body.
6. 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.
7. The jet-propulsion personal watercraft according to claim 6 , wherein the extension portion extends from an outer end portion of the hull protruding portion or an outer end portion of the deck protruding portion.
8. 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.
