The Navigation Rules & Regulations Handbook (Nav Rules) contains the essentials of boating protocol and safety. It is the reference manual every boat should carry and every skipper should be intimately familiar with. So valuable in fact the US Coast Guard REQUIRES a copy on board all vessels 12 meters (approximately 39') or more in length:

"33 CFR 83.01(g) requires: 'The operator of each self-propelled vessel 12 meters or more in length shall carry, on board and maintain for ready reference, a copy of these Rules.'

This handbook is a compendium produced by the U.S. Coast Guard Navigation Standards Branch, U.S. Coast Guard Headquarters, Washington, DC, of the:

• International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS);
