MODEL TESTS AND/OR FULL-SCALE EXPERIMENTS ON "UNCONVENTIONAL MANOEUVRING DEVICES" U.M.D.--COLLECTED REPLIES TO A QUESTIONNAIRE

This questionnaire was sent to some 100 organizations in April 1974. Replies have been received from 20 of them, 12 of which have contributed 22 completed questionnaire forms, which are reproduced in this paper. The information obtained provides a picture of the different "unconventional manoeuvring devices" currently in research and development, which improve the manoeuvring qualities at low and medium ship-speed, when the main rudder effectiveness is diminishing. It is concluded that the steadily increasing offshore activities and the unusual high time constants of large vessels manoeuvring in channels, or in confined waters, urgently require continuing research and development in this field. Order from; BSRA as No. 48,771.
