Sea-trial experimental results of fin/rudder roll stabilisation

Abstract

This paper reports on full-scale roll stabilisation trials on board a frigate-size Royal Naval warship. The trials entailed comparing the efficacy of the fins functioning alone, with the combined effects of the fins and rudders operating in congress to reduce roll motions. The rudders were employed in a supplementary role and no mechanical modifications were made. To afford a comparison of the results the data acquired is presented in the RMS form. © 1995.
