The paper deals with a method to measure and analyse hull surface pressure and with interp-retation of the results for application to hull form design. A new and simple method to measure pressure in the proximity of free surface is introduced at first, and then, integration of the measured pressure is introduced to examine a pressure drag. This new method of integration does not require any conventional correction term due to the sinkage and trim of a ship. Further, some application examples of the above methods for studying the following data are intro-duced. ・Wave profiles and pressure distribution on hull surface in breaking wave at the bow ・Pressure distribution over the hull surface in the fore and aft body ・Skin friction resistance derived by deducting the pressure resistance from the total resistance ・Viscous pressure resistance derived by deducting the wave pattern resistance (obtained througth the wave analysis) from the pressure resistance ・Pressure components of thrust deduction obtained from the pressures measured with and without a propeller The measurements for the above application were conducted at the Towing Tank of IHI (Ishikawa-jima-Harima Heavy Industries Co., Ltd.).
