Patent ID: 7980904

Claim:
A jet-propulsion personal watercraft comprising: a body including a hull and a deck; an engine mounted to the body; a driving power output changing system configured to be able to change a driving power output of the engine; a controller configured to control an operation of the driving power output changing system; a pressure sensor configured to be able to detect a pressure which is applied to the body from water on which the body is floating, the pressure having a component in a lateral direction of the body; wherein the controller includes a turning determiner configured to determine whether or not the body is turning in the lateral direction by steering the body, based on a signal received from the pressure sensor; and a driving power output control unit configured to control the driving power output changing system based on information received from the turning determiner; wherein the controller includes a deceleration determiner configured to determine whether or not the watercraft is decelerating; and wherein the driving power output control unit is configured to control the driving power output changing system to maintain a propulsion force for turning the body, when the deceleration determiner determines that the watercraft is decelerating and the turning determiner determines that the body is turning.
