摘要： In a watercraft, a storage device stores area information including position information regarding a specified area. A controller compares a current position of a watercraft main body obtained by a global navigation satellite system receiver to the position information related to the specified area. The controller controls the watercraft main body in accordance with a normal mode when the current position of the watercraft main body is within the specified area. The controller controls the watercraft main body in accordance with a limited mode in which at least a portion of a plurality of functions of the watercraft main body are limited in comparison with the normal mode when the current position of the watercraft main body is not within the specified area.

摘要： A watercraft has an engine that is controlled to provide a comfortable and natural operational feeling during an off-throttle steering environment. The engine is controlled by detecting engine speed, using the detected engine speed to establish an accurate watercraft speed, and detecting an operator steering torque and operator engine torque request. An operational characteristic of the engine is adjusted to increase the engine output by a predetermined amount after a predetermined steering torque is measured and the watercraft is determined to be in a predetermined deceleration phase. The operational characteristic can be an increase in airflow to the engine.

摘要： In a watercraft, an engine rotational speed sensor detects a rotational speed of an engine. A determining section determines if a prescribed execution condition indicating that a hull body is moving is satisfied. A filter processing section applies a filter process to the engine rotational speed detected by the engine speed sensor to acquire a filtered engine rotational speed. A control section executes a maximum speed limiting control to limit a maximum speed of the watercraft when the prescribed execution condition is satisfied and the filtered engine rotational speed is larger than a prescribed rotational speed threshold value.

摘要： A water jet propulsion watercraft includes a hull, an engine disposed inside the hull, a jet propulsion device arranged to be driven by a driving force of the engine, a water detection unit arranged to detect whether or not the hull is immersed in water, and a control unit arranged to restrict an engine rotational speed. The jet propulsion device is arranged to jet water rearward from a jet port to thereby apply a propulsive force to the hull. The water detection unit includes a water detection chamber arranged such that water around the hull is introduced when the hull is in water, and a water level sensor arranged to detect a water level inside the water detection chamber. The control unit is arranged to judge whether or not the hull is in water based on an output signal of the water level sensor and to set a maximum rotational speed of the engine to a rotational speed less than an upper limit rotational speed so as to restrict the rotational speed of the engine to not more than the maximum rotational speed when the hull is not in water.
