Abstract
There is provided an automatic steering device with which an optimal duty ratio for achieving an optimal rudder turning speed at a cruising speed can be found simply and accurately. An automatic steering deviceincludes a correspondence acquisition componentand a duty ratio calculator. The correspondence acquisition componentfinds a correspondence between a duty ratio and a rudder turning speed based on a first rudder turning speed while a steering mechanismis controlled at a first duty ratio, and a second rudder turning speed while the steering mechanismis controlled at a second duty ratio. The duty ratio calculatorcalculates the duty ratio corresponding to a specific rudder turning speed based on the correspondence found by the correspondence acquisition component
