A Guide to the Collision Avoidance Rules is the essential reference to the safe operation of all vessels at sea. Published continuously since 1965, this respected and expert guide is the classic text for all who need to, practically and legally, understand and comply with the Rules. This sixth edition incorporates all of the amendments to the International Regulations for Preventing Collisions at Sea which came into force in November 2003. The books sets out all of the Rules with clear explanation of their meaning, and gives detailed examples of how the rules have been used in practice by seafarers, as well as excerpts from Court judgements to illustrate how they have been interpreted in practice. Written for masters, navigating officers, senior crew, cadets and those in training, plus ship operators, marine lawyers and anyone concerned with the safe operation of shipping, this is an essential reference for at sea and on shore.
