Abstract : This report discusses various techniques which have been employed for making model rudder tests, compares full-scale torque measurements with torques predicted from model tests, and presents conclusions based on the investigations. An improved method of conducting rudder tests for the prediction of ship performance is included, but the report does not discuss the prediction of rudder torques without model tests.
