Abstract

A boat includes a hull, a deck, and a bow hatch. An engine compartment is provided in the hull. The deck is mounted on an upper portion of the hull. The deck includes an air inlet port that opens rearward to supply air to the engine compartment. The bow hatch is attached to the deck. The bow hatch includes a wall that faces the air inlet port.

First claim

What is claimed is:

1. A boat comprising:
a hull including an engine compartment;
a deck mounted on an upper portion of the hull and including an air inlet port that opens rearward to supply air to the engine compartment; and
a bow hatch attached to the deck and including a main body, a cover to cover the main body, and a wall that protrudes from the main body towards the cover and faces the air inlet port.

2. The boat according to claim 1 , wherein
the bow hatch includes an opening to take in outside air; and
the wall is located between the air inlet port and the opening.

3. A boat comprising:
a hull including an engine compartment;
a deck mounted on an upper portion of the hull and including an air inlet port that opens rearward to supply air to the engine compartment; and
a bow hatch attached to the deck and including a wall that faces the air inlet port; wherein
the bow hatch includes a first drain port located between the air inlet port and the wall.

4. A boat comprising:
a hull including an engine compartment;
a deck mounted on an upper portion of the hull and including an air inlet port that opens rearward to supply air to the engine compartment; and
a bow hatch attached to the deck and including a wall that faces the air inlet port; wherein
the bow hatch includes a second drain port located behind the wall.

5. The boat according to claim 1 , wherein
the main body is attached to the deck; and
a tip of the wall is spaced apart at a distance from the inner surface of the cover.

6. The boat according to claim 5 , further comprising:
a drain gap located between the main body and the deck.

7. The boat according to claim 1 , further comprising:
a tiltable operator mounted swingably to the deck via a pivot shaft; wherein
the deck includes an inclined surface on which the air inlet port is provided; and
the inclined surface is oriented so that an angle, defined by the inclined surface and a plane including an axis of the pivot shaft and that extends in a direction in which gravity acts, is equal to or larger than about 20 degrees and equal to or less than about 80 degrees.

8. A boat comprising:
a hull including an engine compartment;
a deck mounted on an upper portion of the hull and including an air inlet port that opens rearward to supply air to the engine compartment; and
a bow hatch attached to the deck and including a wall that faces the air inlet port; wherein
the air inlet port includes a first air inlet port and a second air inlet port;
a first duct and a second duct extend from the first air inlet port and the second air inlet port, respectively, toward the engine compartment;
the first air inlet port is located on a first side spaced apart from a major axis of the hull in a top view, and the second air inlet port is located on a second side opposite to the first side;
a first end of the first duct is located at the first air inlet port and a second end of the first duct is connected to the engine compartment on the second side; and
a first end of the second duct is located at the second air inlet port and a second end of the second duct is connected to the engine compartment on the first side.

9. The boat according to claim 1 , wherein the bow hatch includes a first drain port located between the air inlet port and the wall.

10. The boat according to claim 1 , wherein the bow hatch includes a second drain port located behind the wall.

11. The boat according to claim 1 , wherein
the air inlet port includes a first air inlet port and a second air inlet port;
a first duct and a second duct extend from the first air inlet port and the second air inlet port, respectively, toward the engine compartment;
the first air inlet port is located on a first side spaced apart from a major axis of the hull in a top view, and the second air inlet port is located on a second side opposite to the first side;
a first end of the first duct is located at the first air inlet port and a second end of the first duct is connected to the engine compartment on the second side; and
a first end of the second duct is located at the second air inlet port and a second end of the second duct is connected to the engine compartment on the first side.
