This paper presents a method to estimate the viscous pressure resistance of a ship. First of all, the difference between the pressure calculated by the Hess-Smith's method and the measured pressure is examined on the aft part of some model ships. Through the analysis of this result, a method to estimate the pressure on the stern hull is proposed. Next, the viscous pressure resistances are calculated for some model ships by the integral of the estimated pressure, and compared with the experimental results. As a result of examination, it is found that the present method gives the useful information about a viscous pressure resistance of a ship.
