    Study Notes

    IALA Maritime Buoyage System

    • IALA (International Association of Marine Aids and Lighthouse Authorities) is a non-profit international technical association
    • IALA establishes technical committees with experts from over 80 countries to develop recommendations on buoyage systems and navigation practices.
    • IALA works to harmonise global aids to navigation for safe, expeditious and cost-effective vessel movements while protecting the environment.
    • IALA created a worldwide buoyage system to minimize confusion and ensure safe navigation for mariners in different regions.
    • The buoyage system is divided into two regions: Region A and Region B, based on geographic location (Europe, Australia, New Zealand, Africa, some Asian countries are in Region A, and North, Central, & South America, Japan, North & South Korea, and the Philippines are in Region B).
    • Different types of buoyage marks are used for visual identification.
    • Lateral marks denote channel edges.
    • Cardinal marks indicate hazard locations and safe water direction.
    • Isolated danger marks flag hazards to shipping.
    • Safe water marks indicate navigable water.
    • Special marks highlight features like recreation areas, speed limits, or mooring areas.

    Buoy Characteristics

    • Buoy shapes, colours, topmarks and light patterns distinguish different types of marks and their functions (e.g., lateral, cardinal, isolated danger, safe water, or special)
    • Port Marks (left) and Starboard marks (right) are differentiated by color.
    • Preferred channels are indicated by color bands on lateral marks.
    • Regional differences exist in lateral buoy markings (some features differ).
    • Light colours and rhythms provide nighttime guidance.
    • Cardinal marks have black and yellow markings/topmarks, often with distinctive light rhythms.
    • Cardinal marks indicate the compass bearings for safe navigation through areas with potential hazards.
