As a rudder behind a hull and a propeller has a great influence on the propulsive performance, it is important to research the rudder effects on ship propulsion. Recently, one of the authors presented the method which estimates the propeller-rudder interactive forces qualitatively by paying attention to rudder thickness effects and adapting thick wing theory. The other of the authors performed the propeller load tests of ships without rudder and discussed the propulsive effects as a function of propeller load. In this paper, the authors deal with the problem in the case that a propeller and a rudder are behind a hull. The propeller load test of a ship with a rudder is carried out including a measurement of rudder drag, and the method which estimates the propulsive effects of a rudder by changing the propeller load is discussed.
