Abstract

A vessel includes an outboard motor including an upstream exhaust port that emits exhaust, a hull including a rear portion on which the outboard motor is mounted, a cabin disposed above the hull, a downstream exhaust port disposed farther to a lateral side than the outboard motor, and an exhaust passage extending from the upstream exhaust port to the downstream exhaust port and guiding the exhaust from the upstream exhaust port to the downstream exhaust port. The cabin includes a windshield disposed in front of the outboard motor in a plan view. The height of the cabin from a rearmost end of the outboard motor is not less than ½ or about ½ of a horizontal distance in a front/rear direction from a rear end edge of the windshield to the rearmost end of the outboard motor.

First claim

What is claimed is:

1. A vessel comprising:
an outboard motor including an upstream exhaust port that emits exhaust;
a hull including a rear portion on which the outboard motor is mounted;
a cabin disposed above the hull and including a windshield disposed in front of the outboard motor in a plan view of the vessel, a height of the cabin from a rearmost end of the outboard motor being not less than about ½ of a horizontal distance in a front/rear direction from the rearmost end of the outboard motor to a rear end edge of the windshield;
a downstream exhaust port disposed farther to a lateral side of the vessel than the outboard motor; and
an exhaust passage extending from the upstream exhaust port to the downstream exhaust port and configured to guide the exhaust from the upstream exhaust port to the downstream exhaust port; wherein
the cabin, the outboard motor, and the windshield are configured and arranged with respect to each other to prevent an inflow of the exhaust into the cabin.

2. The vessel according to claim 1 , wherein the downstream exhaust port is disposed farther to the lateral side of the vessel than the windshield of the cabin.

3. The vessel according to claim 1 , further comprising an operator seat disposed in an interior of the cabin.

4. A vessel comprising:
an outboard motor including a crankshaft rotatable about a vertical axis;
a body including a rear portion on which the outboard motor is mounted so as to be rotatable around a pivot shaft extending horizontally in a width direction of the body;
a right downstream exhaust port disposed at a right side of a width direction center of the body;
a left downstream exhaust port disposed at a left side of the width direction center of the body; and
at least one exhaust passage extending from the outboard motor to each of the right downstream exhaust port and the left downstream exhaust port and configured to guide exhaust from the outboard motor to each of the right downstream exhaust port and the left downstream exhaust port; wherein
the at least one exhaust passage passes through a space above the pivot shaft.

5. The vessel according to claim 4 , wherein the at least one exhaust passage includes a collective passage connected to the outboard motor, a right branch passage extending from the collective passage to the right downstream exhaust port, and a left branch passage extending from the collective passage to the left downstream exhaust port.

6. The vessel according to claim 4 , wherein each of the right downstream exhaust port and the left downstream exhaust port is disposed farther to a rear of the vessel than a front end of the outboard motor.

7. The vessel according to claim 4 , wherein the body includes a platform disposed farther to the rear of the vessel than the outboard motor, and each of the right downstream exhaust port and the left downstream exhaust port is located at the platform.

8. The vessel according to claim 4 , wherein the right downstream exhaust port and the left downstream exhaust port are located respectively at a right side surface and a left side surface of the body.

9. The vessel according to claim 4 , wherein at least a portion of the at least one exhaust passage is defined by an exhaust hose.

10. The vessel according to claim 4 , wherein at least a portion of the at least one exhaust passage is defined by the body.

11. The vessel according to claim 10 , further comprising a blower disposed inside the at least one exhaust passage and configured to deliver gas inside the at least one exhaust passage to at least one of the right downstream exhaust port and the left downstream exhaust port.

12. A vessel comprising:
an outboard motor including an upstream exhaust port that emits exhaust;
a body including a rear portion on which the outboard motor is mounted;
a downstream exhaust port disposed farther to a lateral side of the vessel than the outboard motor; and
an exhaust hose configured to guide the exhaust from the upstream exhaust port to the downstream exhaust port, the exhaust hose extending in a horizontal attitude from the upstream exhaust port to an intermediate position between the upstream exhaust port and the downstream exhaust port, and extending in a downward attitude or a horizontal attitude from the intermediate position to the downstream exhaust port.

13. The vessel according to claim 12 , wherein the upstream exhaust port extends upward toward an exterior of the outboard motor.

14. The vessel according to claim 12 , wherein the exhaust hose extends from the upstream exhaust port to a fold-back position farther to a front of the vessel than the upstream exhaust port and the downstream exhaust port and extends rearward from the fold-back position to the downstream exhaust port.

15. The vessel according to claim 14 , wherein the outboard motor is mounted on the rear portion of the body so as to be rotatable around a pivot axis extending horizontally in a width direction of the body, the pivot axis being disposed at a position farther to the front of the vessel than the upstream exhaust port and the downstream exhaust port; and
the exhaust hose extends from the upstream exhaust port to a vicinity of the pivot axis and extends from the vicinity of the pivot axis to the downstream exhaust port.

16. A vessel comprising:
an outboard motor including an upstream exhaust port that emits exhaust;
a body including a rear portion on which the outboard motor is mounted;
a downstream exhaust port disposed farther to a lateral side of the vessel than the outboard motor; and
an exhaust hose configured to guide the exhaust from the upstream exhaust port to the downstream exhaust port, the exhaust hose extending from the upstream exhaust port to an uppermost position higher than the upstream exhaust port and the downstream exhaust port, and extending from the uppermost position to the downstream exhaust port.
