Abstract

A jet propelled boat includes a boat body including a hull and a deck located above the hull, and a pair of frames, one frame provided on each of a right side and a left side of the deck so as to sandwich the deck in a right-left direction of the jet propelled boat. The deck includes an upper deck and a lower deck, and each of the pair of frames includes a connector that spans the upper deck and the lower deck so as to connect the upper deck to the lower deck.

First claim

What is claimed is:

1. A jet propelled boat comprising:
a boat body including a hull and a deck located above the hull; and
a pair of frames provided respectively on a right side and a left side of the deck so as to sandwich the deck in a right-left direction of the jet propelled boat; wherein
the deck includes an upper deck and a lower deck; and
each of the pair of frames includes a connector to connect the upper deck to the lower deck; wherein an opening is provided in each of the pair of frames and defined by a side surface of the upper deck, an upper surface of the lower deck, and an inner surface of the connector of each of the pair of frames that faces the deck.

2. The jet propelled boat according to claim 1 , wherein
the lower deck is larger than the upper deck in the right-left direction; and
the connector of each of the pair of frames is inclined downward and outward in a front view of the jet propelled boat.

3. The jet propelled boat according to claim 1 , wherein the connector of each of the pair of frames is inclined forward and downward toward a lower side of the jet propelled boat.

4. The jet propelled boat according to claim 1 , wherein the pair of frames define a cowling together with a front portion of the upper deck.

5. The jet propelled boat according to claim 1 , wherein each of the pair of frames further includes:
an upper frame integral and unitary with the connector and located above the connector and along an outer surface of the upper deck; and
a lower frame integral and unitary with the connector and located below the connector and along an outer surface of the lower deck.

6. The jet propelled boat according to claim 5 , wherein the lower frame of each of the pair of frames includes an outer surface flush or substantially flush with the outer surface of the lower deck.

7. The jet propelled boat according to claim 6 , wherein each of the pair of frames further includes a rear frame connected to a rear side of the upper frame and extending rearward so as to cover the outer surface of the upper deck.

8. The jet propelled boat according to claim 1 , wherein the connector of each of the pair of frames becomes thicker as the connector extends upward toward an upper side of the jet propelled boat.

9. The jet propelled boat according to claim 1 , wherein the side surface of the upper deck that defines the opening in each of the pair of frames is concave so as to be recessed inward.

10. The jet propelled boat according to claim 9 , wherein the concave side surface of the upper deck that defines the opening in each of the pair of frames is arcuate.

11. The jet propelled boat according to claim 1 , wherein the pair of frames have a V-shape so as to be spaced farther apart from each other as the pair of frames extend toward a front side of the jet propelled boat in a plan view.

12. The jet propelled boat according to claim 1 , wherein the connector of each of the pair of frames includes an outer surface that is convex so as to bulge outward in a horizontal cross-section of the jet propelled boat.

13. The jet propelled boat according to claim 12 , wherein the convex outer surface includes two concave surfaces aligned in a forward-rearward direction of the jet propelled boat and recessed inward in the horizontal cross-section, and one convex portion that connects the two concave surfaces and bulges outward in the horizontal cross-section.

14. The jet propelled boat according to claim 1 , wherein
the deck further includes a footrest to enable a user to place his or her foot thereon; and
the connector of each of the pair of frames is located on a front side of the footrest in a forward-rearward direction of the jet propelled boat.

15. The jet propelled boat according to claim 1 , further comprising:
a pair of reinforcing ribs aligned in the right-left direction so as to extend in an upward-downward direction of the jet propelled boat at a front end of the deck between the pair of frames in a front view.

16. The jet propelled boat according to claim 15 , wherein the pair of reinforcing ribs extend outward and downward away from each other toward a lower side of the jet propelled boat.
