This paper presents the results of open-water tests with a systematic series of contra-rotating propellers, consisting of a four bladed forward screw and a five bladed aft screw. Based on the open-water test results, contra-rotating propeller systems were designed for a tanker and a cargo liner. Comparative tests have been carried out with the tanker and the cargo liner both equipped with contra-rotating propellers and with a conventional screw. The propulsive efficiencies, the cavitation characteristics, the propeller induced vibratory forces and the stopping abilities are dealt with.
