The International Regulations for Preventing Collisions at Sea (COLREGS) are vital for maritime safety as you must be able to identify vessels during the day by their special shapes, and at night time by their lights, as well as understanding both your obligations and those of other vessels as you interact with one another.
This new edition provides a clear and authoritative explanation of each regulation. Illustrations have been enhanced and it will help any seafarer understand their responsibilities, meaning that everybody at sea will be safer. Chapters include:
 
Assessing the Risk
Who Gives Way?
Restricted visibility
Lights and Shapes
Sound and Light Signals
 
In response to feedback, this new edition has been restructured to lead customers through the regulations by rule order, split into themes (i.e. restricted visibility) with a view to helping readers quickly reference the content.
