To improve prediction accuracy in model predictive control.The ship control device includes processing circuitry. The processing circuitry estimates an initial search value of a throttle opening by an estimation method based on uncertainty with a distance between a position of the ship and a target position of dynamic positioning, and a true wind velocity as preconditions. The processing circuitry searches an action for moving the ship to the target position by a model predictive control in a search range having the initial search value as an origin, and determines a command throttle opening based on the search result.
