This report describes the results of experiments using the Maritime Administration Computer Aided Operations Research Facility (CAORF) ship maneuvering simulator to determine if training in the changes to the steering rules of the International Rules of the Road (1977) causes a difference in watch officer behavior in the crossing/meeting collision situations. An additional objective was to determine the differences between two ship types (VLCC and containership) in the same situations. A tightly structured, counterbalanced mixed design with one between- and three within-subject variables was applied to eight realistic experimental scenarios. All scenarios involved failure to give way, in five or twenty-five degree crossings, between a 25 knot containership and a 15 knot VLCC. A half-day, classroom training program, using a sound/slide presentation and case study discussions, was effective in increasing knowledge and understanding of the Rules changes. Transfer of training to the simulator did occur with the trained group. Consistency of performance (range to target ship at maneuver) was significantly improved, fewer course changes per maneuver were made, and better advantage was taken of the rule pertaining to ambiguous meeting/crossing situations by the trained group. The closest points of approach (CPA) for the containership sample were significantly larger than for the VLCCs, even though larger course changes were made by the VLCCs at approximately the same range (4 nm).
