A ship configured to obtain propelling force by driving a main propeller with a main engine is provided with an additional propeller and a driving unit therefor. The additional propeller is disposed at a ship bottom or at a rising section of the ship bottom, in a position different from the main propeller. Further, the output of the driving unit of the additional propeller is 25% or less than the output of the driving unit of the main engine, and the operating condition can be selectable between regular operating condition in which propelling force is obtained by driving the main propeller and the other operating condition in that propelling force is obtained by driving the additional propeller.
