USCG NAVIGATION RULES AND REGULATIONS HANDBOOK

Please see the new Amalgamated version

Navigation Rules is a publication that contains the rules and regulations that apply to the operation of ships and other vessels in navigable waters. These rules are designed to promote the safe and efficient operation of ships, and to prevent collisions and other accidents.

The navigation rules book typically includes information on:

• The "rules of the road," which are the specific rules that apply to the movement of vessels in different situations, such as when two vessels are approaching each other, or when a vessel is crossing the path of another vessel.
• Signals and signals of distress, which are the signals and procedures that are used to communicate with other vessels and to indicate when a vessel is in distress.
• Lights and shapes, which are the signals that are used to indicate the nature and intentions of a vessel, such as whether it is underway or at anchor.
• Sound signals, which are the signals that are used to communicate with other vessels using sound, such as horn blasts or whistles.
• Aids to navigation, which are the systems and devices that are used to help vessels navigate, such as lighthouses, buoys, and radar.

The navigation rules book is an important reference for all vessel operators, as it contains important information that is necessary for the safe operation of ships. It is typically required to be on board all vessels and to be readily available for reference.
