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