Abstract
A ship handling device enabling easy turning calibration. With a ship handling device (7), during turning calibration with the ship handling device (7), the joystick lever (10) is turned to rotate the forward-backward propellers (4) on the port and starboard sides of the ship, and the joystick lever (10) is tilted to change a forward-thrust/backward-thrust ratio of the forward-backward propeller (4) on the port or starboard side or to change the rotation speeds. When a calibration execution switch (10a) is operated, thrusts generated with the changed forward-thrust backward-thrust ratio are set as correction coefficients, or, among thrusts generated at the changed rotation speeds (Npn, Nsn) of the forward-backward propellers (4) on the port and starboard sides, thrusts generated by the forward-backward propellers (4) on the port and starboard sides according to the tilting of the joystick lever (10) are set as correction coefficients (Cp, Cs).
