Heading control device and heading control method for ship

摘要

An object is to obtain a heading control device and a heading control method for ship in which a heading control system is configured on the basis of ship motion information, without promoting oscillation excited by disturbance factors to the ship, such as tidal current or wind. The heading control device for ship, which causes a ship provided with an outboard motor to sail at a desired heading, includes: a heading generator which outputs a heading command; and a controller which outputs a rudder angle command on the basis of the heading command from the heading generator, sensor group information from a sensor group, and ship motion characteristic information from a ship motion characteristic information storage unit.
