This is the definitive work on the Collision Avoidance Rules for all concerned with the practical and legal aspects of their interpretation. This new edition incorporates the 1993 Amendments to the International Regulations for Preventing Collisions atSea 1972, which came into force in 1995. The book sets out all the Rules with clear comments on their meaning and on the significance of the changes, and with excerpts from Court judgements that show how they have been interpreted in law. Arrangements of lights and signals are illustrated in colour, and diagrams explain certain aspects of the Steering and Sailing Rules.
