Query: Excellent Reference

Behavior and Handling of Ships is an excellent tool for the professional mariner and is a great addition to any collection of maritime reference materials. The book itself revolves almost entirely around handling large, single-screw merchant vessels so it is very focused in its application; however, it does an excellent job in doing so. What is most impressive about this work is the way the author describes to the reader the forces from the wind and current that act upon a ship - and how the operator can overcome them....or NOT overcome them!! He also goes into depth on the effective use of tugs, thrusters and the anchor. Toward the end of the book, the author lists a number of practical applications that are excellent reading. In all, the book delivers as promised in a very concise, straight-forward manner.
