This is a massive work involving an extensive examination of collision law, probably matched only by Mardsens Collisions at Sea, now part of the British Shipping Laws series. The depth of the books research base reflects the fact that it is the culmination of many years of intensive research work and very thorough legal scholarship. It is neither necessary nor appropriate to say anything specific about the actual content of a work that speaks for itself. Suffice it to say that it is one of the best and most important maritime law books to appear anywhere in many years.
