Abstract

A sailing assisting system is provided in which a sailing assist for a vessel which enters a specific water area where sailing of the vessel is limited is realized through a simple configuration and in which a steersman is prevented from having strange feeling. A sailing assisting system includes movable controlling devices (a shift and throttle controller, a steering device, a trim switch), actuators (a rotational shaft drive unit, a shaft drive unit, a switch drive unit) for driving these controlling devices, and a control unit for executing a notification operation and controlling the actuators to limit movable ranges of the controlling devices if a hull is determined to stay within a specific water area where the sailing of the hull is limited based on information on the specific water area and information on the position of the hull.

Claims6

Dependent claims

A sailing assisting system for a vessel comprising:

a movable controlling device configured to instruct a revolution speed of a propeller included in a propelling system for the vessel and a posture of the propelling system;
a movable controlling device actuator that is configured to drive the movable controlling device;
a hull positional information acquisition unit that is configured to acquire positional information of a hull to which the propelling system is attached;
a hull location determination unit that is configured to determine, based on the positional information and information on a specific water area where sailing is limited, whether the hull stays within the specific water area or whether there is a possibility that the hull enters the specific water area;
and
an actuator control unit that is configured to control the actuator to limit a movable range of the movable controlling device by applying an operation reaction force to the movable controlling device if the hull location determination unit determines that the hull stays within the specific water area or that there is the possibility that the hull enters the specific water area.
