A program was initiated to evaluate the effect of a Kort nozzle propulsion system at high slip ratios and in the free running condition. To accomplish this, it was suggested that both a fixed Kort nozzle, which would require a steering rudder for free running and two flanking rudders for backing, and a rotating Kort nozzle be investigated. The rotating nozzle could satisfactorily propel the craft as well as steer it. However, if desirable, a steering rudder could be installed so that it would only be necessary to rotate the nozzle when large thrust forces were needed as for backing. The actual test program consisted of ahead and backing propulsion, side thrust, and bollard pull tests for an open screw system, a fixed Kort nozzle system, and a rotating Kort nozzle system.
