Abstract
A ship body control device is provided, which includes a rudder controller configured to control a rudder angle of a ship, a sensor configured to measure a ship body direction of the ship, and an autopilot controller configured to output a rudder angle command to the rudder controller. The autopilot controller includes an angle-of-deviation calculating module configured to calculate a deviation angle of a stern direction from a target stern direction based on the ship body direction, and a rudder angle command setting module configured to set the rudder angle command so as to maintain a current rudder angle when the deviation angle is less than a first threshold, and to change it to a given fixed turning rudder angle when the deviation angle is the first threshold or more.
