BUOYAGE SYSTEM

MARITIME BUOYAGE SYSTEM Until recently, as many as 30 different buoyage systems were in use around the world. In 1982, most of the maritime nations of the world signed an agree- ment sponsored by the International Association of Lighthouse Authorities (IALA). This agreement adopted a system known as the IALA Maritime Buoyage System and provides rules that apply to all fixed and floating marks other than lighthouses, sec- tor lights, range lights, lightships, and large automatic navigational buoys (LANBYs).
