The propulsive performance of the propeller affected by different types of rudders were investigated by the circulating water tank using propeller open test apparatus and self-propelled model ship. The types of rudders were NACA0022 and Reaction rudder with or without parallel auxiliary foils attached near the trailing edges of main rudders. The obtained data were analyzed into three self-propulsion factors, namely, thrust deduction coefficient, wake coefficient and relative rotative efficiency. The result showed us that the reaction rudder with auxiliary foils is most effective against relative rotative efficiency among other types of rudders.
