Which document governs the use of IALA buoyage systems worldwide?

The IALA Maritime Buoyage System Manual is the definitive guide for the use of buoyage systems worldwide, as established by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). This manual provides comprehensive information about the standardization of buoyage systems, including the types, colors, shapes, and markings of buoys used to aid navigation in waters globally. It is essential for promoting safety at sea by ensuring consistency and clarity in navigational aids, which helps mariners understand their significance and role in maritime navigation.

The other documents mentioned, while they may address aspects of maritime safety or navigation, do not specifically govern the universal application of buoyage systems as outlined by IALA. The International Maritime Organization Guidelines may provide broad regulations or recommendations about maritime practices, but they do not focus solely on buoyage systems. Similarly, the Maritime Safety Act and the Buoy Maintenance Regulation may pertain to specific national regulations or maintenance practices but do not offer the same comprehensive guidance on the buoyage systems as the IALA manual.
