The rudder in the slip stream of a propeller has a great effect on the propulsive performance of a ship. The problem on the propeller and rudder mutual interaction theoretically has been dealt with by using the rudder theory based on the thin wing theory, and the interactive forces have been discussed. In the previous report, the authors dealt with a rudder as the thick wing in the propeller slip stream, and discussed the interactive forces and the flow field near the rudder in comparing with the results of propeller and rudder interaction tests in the cavitation tank of the Ship Research Institute. In this paper, the rudder surface pressure is measured in the cavitation tank of S.R.I. And the formulae on the pressure acting on a rudder in the non-potential propeller slip stream are given, and then the numerical results are compared with the experimental results. The method on estimating the rudder drag by using the rudder surface pressure formulae and the boundary layer theory is shown.
