Abstract
A ship steering device including: an engine; an auto-drive unit that exerts propulsive power on a ship hull by power from the engine; detection means for detecting a current position and an orientation of the ship hull; a ship steering control device that controls an output of the engine and propulsive power of the auto-drive unit; and a calibration switch that starts calibration of a ship. When the ship steering control device detects that the calibration switch is turned on, the ship steering control device controls the engine and the auto-drive unit to cause the ship hull to move in a predetermined direction or to turn, and if a difference between, for instance, a traveling amount and speed in the predetermined direction and an intended traveling amount and speed exceeds a predetermined value, the ship steering control device corrects control values of the engine and the auto-drive unit.
