A ship handling device capable of executing dynamic positioning control. While the dynamic positioning control is being active, if a distance deviation from a target position exceeds a predetermined value and a first condition that a state where a moving amount of the ship per unit time is not more than a predetermined amount has continued for a predetermined period is satisfied, or if an orientation deviation from a target orientation exceeds a predetermined value and a second condition that a state where a turning amount of the ship per unit time is not more than a predetermined amount has continued for a predetermined period is satisfied, a thrust setting value resulting from the dynamic positioning control at a determination on the first or second condition is stored as a reference value, and the reference value is added to a thrust setting value subsequently resulting from the dynamic positioning control.
