Abstract
The purpose is providing a ship handling device easily determining a predetermined correction coefficient regardless of positions of a side thruster and a forward/backward propeller and the center of gravity of a ship and the shape of the ship. The device is provided with a joystick lever for indicating a propulsion direction and the magnitude of thrust by tilting direction and angle, wherein: a lateral movement thrust is generated by the side thruster in accordance with the joystick lever; a first correction thrust is generated by the forward/backward propeller in accordance with the joystick lever so as to cancel out a rotation moment; and a first correction coefficient for calculating a first correction thrust with respect to the lateral movement thrust is determined.
