1. A ship handling device configured to make a ship move to target coordinates and turn to a target orientation based on a signal from a GPS device and a signal from an orientation sensor, wherein the ship handling device is configured to calculate the target coordinates and the target orientation based on an amount of operation on an operating tool, set a movement control stop zone based on the target coordinates, set a turn control stop zone based on the target orientation, make the ship move toward the target coordinates and turn to the target orientation after acquiring a signal finalizing the target coordinates and the target orientation, and control the ship in such a manner that, when current coordinates calculated from the signal from the GPS device are in the movement control stop zone and a current orientation calculated from the signal from the orientation sensor is in the turn control stop zone, the current coordinates and the current orientation are maintained.
