摘要： In a ship control system of one embodiment, a main engine controller performs, when controlling the rotational frequency of a main engine based on a target ship speed of a ship, feedback control of an actual ship speed of the ship to perform ship speed control for bringing the actual ship speed closer to the target ship speed. A turning judgment unit judges whether or not the ship will turn. A control change unit performs, when the turning judgment unit has judged that the ship will turn, lowering processing for lowering the responsiveness of the ship speed control.

摘要： A posture control system for a hull includes trim tab main bodies as posture control plates attached to a stern of the hull to control the posture of the hull. Trim tab actuators drive the trim tab main bodies. Engines generate a propulsive force on the hull. A controller controls the trim tab actuators. Based on a throttle opening angle of the engines, the controller determines a time when the trim tab main bodies are to be lowered by the trim tab actuators.

摘要： Conventional surfboards enable a rider to catch a wave and ride towards the shoreline while utilizing the power of the ocean to enjoy the ocean waves uniquely. A low-profile motorized surfboard has been developed to assist riders who may have a disability or struggle to get into the position necessary to begin riding the waves. The surfboard may comprise at least one propeller and electromechanical motor, which may provide propulsion for the rider. The surfboard may have an internal power system and supporting circuitry for safe and reliable propulsion. The motorized surfboard may have a low-profile system that is collapsible and allows for the rider to enjoy the surf as if the surfboard were a conventional system. The system may also function to return the rider to the shoreline.

摘要： An outboard motor is provided with: an encoder which detects the rotational speed of an engine; a position sensor which detects an operating position of a shift lever; and a state quantity detection unit which detects a state quantity of a shift actuator. A control device of the outboard motor determines whether the state quantity is more than or equal to a stop-initiating threshold value when the operating position has been switched. If the state quantity is more than or equal to the stop-initiating threshold value, the control device implements a stop control to stop ignition and/or fuel injection in the engine.

摘要： Systems and methods for operating watercraft are provided. One method of operating a watercraft includes detecting a presence of an obstacle in proximity to the watercraft. When a propulsion command is received when the presence of the obstacle is detected, an actual output from a powertrain of the watercraft is restricted to a restricted output associated with the presence of the obstacle.

摘要： A hull control device is provided, which includes an error distance calculating module, an approaching speed calculating module and a command value setting module. The error distance calculating module calculates an error distance between a target position of a fixed-point hold and a ship position. The approaching speed calculating module calculates an approaching speed of a ship to the target position. The command value setting module sets a throttle command value according to a combination of the error distance and the approaching speed.

摘要： A ship body control device is provided, which includes a control lever having a neutral position, and processing circuitry. When the control lever is moved during an automatic cruise, the processing circuitry executes a deceleration control from a speed of a ship body during the automatic cruise, and when the position of the control lever is in agreement with a position for changing to a manual cruise, the processing circuitry changes the automatic cruise to the manual cruise at a rotating speed of an engine according to the position for changing to the manual cruise.
