Several approaches to problems involved in efforts to improve ship stopping performance were investigated. A non- linear mathematical model with experimentally determined coefficients was used to make repeated computations of stopping maneuvers. Pure longitudinal motion is assumed in most of the report. However, the lateral motions of ships during the stopping maneuver are discussed, and the alternative of turning versus stopping to avoid collision is considered. It is shown that the merits of various methods for improving performance depend largely on ship speed-of- approach. For example, hydrodynamic drag devices are excellent at cruising speed, but are of little use at docking speed. Other broad conclusions are made, but emphasis is on the fact that consideration of individual ship characteristics and requirements must enter into any study of ship-stopping. A Series 60 cargo ship and a medium-sized tanker are subjects of the work. (Author)
