The case in favor of ducted propellers, as shown by increases in propulsive efficiency and maneuverability at large rudder angles, has been proven, but a question as to cavitation and erosion characteristics remains. This article reports on cavitation tests, both model and full-scale, which were performed on a variety of ship types, including VLCC's, an ore carrier and an LPG carrier. The experimental apparatus, the tests which were performed and the conclusions which were reached, are all discussed.
