International Maritime Organization (IMO) adopted the interim standards for ship manoeuvrability A751(18) in 1993 for preventing the marine disasters. These standards cover the typical manoeuvrability including turning ability, course-keeping and yaw-checking ability and stopping ability. As these standards, however, were not settled under the sufficient manoeuvrability data, it was noted that they should be reviewed and finalised after practical experiences. For this purpose, the Ministry of Transport of Japan has been gathering the many trial data for these 5 years, and pointed out that the criteria regarding to course-keeping, yaw-checking and stopping abilities have some problems in the practical application to the actual ships [IMO DE35 INF.14]. In this paper, the authors review the manoeuvrability standards particularly focussing the criteria for the course-keeping and yaw-checking abilities in the present interim standards. Firstly, the indices for these abilities are discussed. Then, the criteria are evaluated based on the many trial data as well as theoretical and simulator studies. Finally, some proposals are summarised for the revise of the interim manoeuvrability standards.
