Claim 0:
1. A ship body control device, comprising:
a sensor configured to measure a ship body direction of the ship; and
processing circuitry configured:
to calculate an angle of deviation of a stern direction of the ship from a target stern direction of the ship based on the ship body direction;
to set a rudder angle command so as to maintain a current rudder angle when the angle of deviation is less than a first threshold, and change the rudder angle to a given fixed turning rudder angle when the angle of deviation is the first threshold or more;
to control a propulsion force of the ship;
to set a propulsion force command so that:
the propulsion force is zero when the angle of deviation is less than a second threshold, and
the propulsion force is a value according to the angle of deviation when the angle of deviation is the second threshold or more.
