## Abstract

A boat includes a hull, a deck, a steering pole, and an information display. An engine is provided in the hull. The deck is mounted on an upper portion of the hull. The steering pole is swingably mounted to the deck via a pivot shaft. The information display is located on the deck in front of the pivot shaft.

## Claims

### Claim 1

A boat comprising:
a hull in which an engine is located;
a deck mounted on an upper portion of the hull;
a tiltable operator swingably mounted to the deck via a pivot shaft; and
an information display located on the deck in front of the pivot shaft; wherein
the deck includes an inclined surface accommodating the information display; and
the information display is positioned on the deck such that a ratio of a radius of a circle around an axial center of the pivot shaft and that contacts the inclined surface in a side view to a maximum length from the axial center of the pivot shaft to an outermost end of the tiltable operator is equal to or larger than about 0.05 and equal to or less than about 0.30.

### Claim 2 (depends on 1)

The boat according to claim 1, wherein the inclined surface is inclined at an angle, defined by the inclined surface and a plane including an axial center of the pivot shaft and extending in a direction in which gravity acts, that is equal to or larger than about 0 degrees and equal to or less than about 60 degrees.

### Claim 3 (depends on 1)

The boat according to claim 1, further comprising:
a bow hatch connected to the deck; wherein
a swing angle of the tiltable operator is defined as 0 degrees in a state where the tiltable operator is positioned on the bow hatch; and
the tiltable operator is swingably mounted on the deck so that the swing angle of the tiltable operator is equal to or larger than about 0 degrees and equal to or less than about 80 degrees.

### Claim 4 (depends on 1)

The boat according to claim 1, further comprising:
a water stopper located between the information display and the deck.

### Claim 5 (depends on 4)

The boat according to claim 4, wherein
the deck includes a hole;
a groove is provided on an outer periphery of the water stopper; and
the groove is fitted to the hole.

### Claim 6 (depends on 4)

The boat according to claim 4, wherein the information display is located in an internal space defined by the hull and the deck and is mounted to the water stopper.

### Claim 7

A boat comprising:
a hull in which an engine is located;
a deck mounted on an upper portion of the hull;
a tiltable operator swingably mounted to the deck via a pivot shaft;
an information display located on the deck in front of the pivot shaft; and
a bow hatch connected to the deck; wherein
a swing angle of the tiltable operator is defined as 0 degrees in a state where the tiltable operator is positioned on the bow hatch; and
the tiltable operator is swingably mounted on the deck so that the swing angle of the tiltable operator is equal to or larger than about 0 degrees and equal to or less than about 80 degrees.

### Claim 8

A boat comprising:
a hull in which an engine is located;
a deck mounted on an upper portion of the hull;
a tiltable operator swingably mounted to the deck via a pivot shaft;
an information display located on the deck in front of the pivot shaft; and
a water stopper located between the information display and the deck.

### Claim 9

A boat comprising:
a hull in which an engine is located;
a deck mounted on an upper portion of the hull;
a tiltable operator swingably mounted to the deck via a pivot shaft;
an information display located on the deck in front of the pivot shaft; and
a bow hatch located behind the pivot shaft and connected to the deck.
