Recently the high speed passenger boats of semi-displacement type are going to increase, and the improvement of their performance is strongly desired. From this point of view the experimental studies on the boat concerned were carried out. As for the hull, for the purpose of improving the propulsive perfomance, four large model ships were used, and the improvements of the hull form and appendages were achieved. As for the propeller, since it become clear that the propeller of the boat caused intense cavitation, its improvement was ashieved. Moreover, seakeeping qualities are important for passenger boats, therefore, by using the original hull form and the improved one, some tests in waves were performed. As the results, the propulsive performance was improved by 18%, propeller cavitation was reduced drastically.
