The efficiency of propeller relation with the velocity of efflux plane, the distribution of axial velocity, the ratio of power required by the propeller and the power delivered to the propeller. This study investigated the current design of ship propeller to determine the efficiency impact on coastline. Propeller from RV Discovery is used in this study. The performance and the efficiency of the propeller were determined by using JavaProp software. The efficiency of the propeller is 50% which was good based on the propeller design. The environmental performances were determined by the range and speed of the distribution of axial velocity. The result has showed very good agreement with the previous research to validate the result.
