Colregs Hard Copy

The International Regulations for Preventing Collisions at Sea (Colregs) can be purchased from http://maritimeknowhow.com in a hard copy.

This book has 449 pages and gives the reader numerous comments on the official law text. It is also enhanced with a great number of figures (most of them with supporting colours). Many "Marine Guidance Notes (MGN" give the seafarer important information on how to handle the ship when risk of collision occurs.

It is an indispensable tool for students, officers of the watch (OOW), fishermen, yachtmen and even lawyers and the like.
