By prescribing a certain surface pressure distribution, a new foil section is designed to give less cavitation and higher lift-drag ratio in comparison to a MAU type one. Using the cavity flow theory proposed by the authors in a previous paper, it is predicted that cavitation performance of the new foil section is better than that of the MAU type one. Experiments were performed in order to verify these facts, using both foil sections. It was found that the difference of cavitation performance between the two foil sections was more than predicted, because for the MAU type section the predicted cavity was smaller than the experimental one.
