Many high-speed planning vessels with speeds of 50 knots or higher adopt surface-piercing propellers that operate in partially submerged conditions with an air film formed on the propeller blade surfaces. Compared to conventional propellers, there is a lack of research on the performance of surface-piercing propellers. In this study, propeller open-water tests were conducted in a towing tank, considering the actual operating conditions. The test propeller used was the Modified Model-841-B, which was a modification of the Model-841-B propeller (Olofsson 1996). Thrusts, torques, and efficiencies were measured and calculated for two different surfacepiercing propellers with different pitch ratios for various immersion ratios, shaft inclination angles, and Froude numbers. Propulsion performance and efficiency were evaluated for each condition. The effects of the operating conditions on the propeller performance were analyzed.
