1. A boat comprising:
a hull;
a float that supports the hull;
a suspension that is disposed between the hull and the float and absorbs a vibration transmitted from the float to the hull; and
a conversion mechanism that converts an energy generated in accordance with a relative movement of the hull and the float in a vertical direction,
wherein the conversion mechanism is arranged so as to sandwich a center of gravity of the hull in a forward-rearward direction,
when a distance from the center of gravity of the hull to the conversion mechanism located at a rearward position is X, and a distance from the center of gravity of the hull to the conversion mechanism located at a forward position is Y, a relationship of X>Y is satisfied,
the conversion mechanism includes: a rack gear that is fixed to the float and is movable upward and downward relative to the boat; a pinion gear that engages with the rack gear; and a motor having a rotation shaft to which the pinion gear is fixed,
the hull includes a battery that is electrically connected to the motor,
the rotation shaft extends in a direction perpendicular to the vertical direction,
a size of the motor is smaller than a size of the battery in the vertical direction, and
the motor and the battery are stored in a storage room.
