A Proposed Basis for Evaluating Ship Maneuvering Performance,

In late 1981 Tracor Hydronautics, Inc., completed a study designed to provide a rational, quantitative basis for evaluating the maneuvering performance and capabilities of commercial vessels larger than 1,000 metric ton displacement. The study was motivated by a long term awareness of the need for maneuvering performance standards and by the requirement that the Coast Guard provide rules and regulations governing ship safety and pollution control. At the initiation of the study, few standards or requirements for ship maneuvering and stopping performance were known to exist. It seemed clear that standards should be based on some type of performance rating, should be generally acceptable in format to industry, and should reflect inherent ship controllability under conditions typical of those under which most ship maneuvering, and most CRG collision, ramming, and grounding casualties, occur.
