The maneuverability standard of ships is now discussed at the International Maritime Organization (IMO) and the allowable limit in directional instability is of great importance. In the present report, the simulation studies on course-changing maneuvers to be conducted by pilots are reported and the allowable limit of directional instability of ships is examined. In such simulations, the ships were forced to pass some waterways by avoiding many fishery nets there expanded. The pilots were requested to evaluate maneuvering difficulty for the tested ships to be different in directional instability and in size, and the results of the maneuvers were carefully analyzed. After reporting such results, the allowable limits are proposed from the viewpoints of the stability of the control system and also the necessary margin in control force. Summarizing the results of the simulator studies to have been shown in the first to third reports and the on-board investigations to be carried out by the Japan Pilots Association, the final proposal for the standard in directional instability of ships is expressed.
