Outline of Final Research Achievements	It has been well known since long ago that opposite direction pre-swirl inflow to propeller rotation due to fins in front of propeller decreases delivered horse power, namely increases propulsive performance. In this study, the effect of pre-swirl inflow on propulsive performance was elucidated by fundamental experiment and optimization method for propeller blades considering increment of hull resistance due to fins in self-propelled condition and appropriate propeller rotational speed was developed. The usefulness of the present optimization method was confirmed by the performance test of the improved propeller in pre-swirl inflow.
