Abstract
This ship propulsion device is equipped with an energy-saving appendage 5 which is located forward of a propeller 1 and which has a curved surface having a radius R smaller than the radius r of the propeller 1. The pitch of the blades 3 of the propeller 1 has a pitch distribution having a local minimum point S where the pitch is smallest at a position radially inward of the radius R of the energy-saving appendage 5.
