Paper 11. Yaw Motion Stability;Twin-Screw,Twin-Rudder Ships—Some Model and Ship Results

Abstract

This paper describes the pull-out manoeuvre as an indication of yaw motion stability. Results of model tests at the Admiralty Experiment Works and full-scale trials data are presented as a demonstration of ship/model correlation; additional model test results are given to illustrate use of the manoeuvre for detecting changes in stability due to alterations in ship configuration.
