This invention intends to provide a ship handling device capable of executing dynamic positioning control with which fixed-point maintaining accuracy including measurement accuracy of a satellite positioning system can be assessed. In this ship handling device (7) for a ship (100) executing the dynamic positioning control for maintaining a ship body (1) at a target position (Y) using a GNSS device (13), a positioning accuracy level (19) of the GNSS device (13) is calculated based on a radio-wave reception state of the GNSS device (13), a fixed-point deviation amount level (20) is calculated based on a fixed-point deviation amount calculated based on the target position (Y) and a measured position (X) measured by the GNSS device (13), and a fixed-point maintaining accuracy level (21) indicative of an assumed range of an absolute position (Z) of the ship body (1) relative to the target position (Y) is determined with reference to the positioning accuracy level (19) and the fixed-point deviation amount level (20).
