Aids to Navigation (AtoN) buoys are essential for guiding vessels safely through waterways, marking hazards, and ensuring efficient maritime operations. Their standardized design, as regulated by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA), helps create a globally recognized system for safe navigation.
🔹 Identification of Navigation Buoys
Navigation buoys are classified based on their function and appearance:
✅ Lateral Marks – Define channel boundaries (Port/Starboard)
✅ Cardinal Marks – Indicate safe water relative to a hazard (North, East, South, West)
✅ Safe Water Marks – Show navigable waters in all directions
✅ Isolated Danger Marks – Warn of specific underwater hazards
✅ Special Marks – Highlight designated areas such as anchorages, pipelines, or restricted zones
Each buoy follows IALA Region A or B color schemes, prescribed light characteristics, and specific structural requirements, ensuring consistency for mariners worldwide
