In all the years between sail and radar the rules which govern ships in proximity have never been optimized. They embody at least three serious defects: Incomplete, they permit two ships using radar to contest the same water without first resolving their order of preference. Complicated, they incorporate too many criteria of responsibility, doubling the possibility of error. Unfair, they allow any ship to change a safe situation into a dangerous one that may have to be rectified by another ship. They also give priority in some cases to a fast ship when the slower has not the ability to evade. A parametric analysis of essentially all possible two-ship encounters raises questions whether too often the system is responsible for the faults of the man. The study suggests remedies.
