Abstract:
A ship speed control device is provided, which includes a calculator and a throttle command value setter. The calculator calculates a throttle calculation value based on a difference between an actual ship speed and a target ship speed. The throttle command value setter sets, when the actual ship speed is below a first threshold determined based on a given throttle upper limit and the throttle calculation value is at or above the throttle upper limit, a throttle command value to the throttle upper limit.
