Which regions correspond to IALA Region A?

The correct answer, which identifies the regions corresponding to IALA Region A, encompasses Europe, Australia, and New Zealand. This classification is based on the IALA Maritime Buoyage System, which is designed to provide a standardized system for identifying navigational aids to navigation worldwide.

Region A utilizes a specific buoyage system that is distinct from Region B. In IALA Region A, lateral buoys indicate the port side with red marks and the starboard side with green marks when entering a harbor. This orientation is critical for mariners to safely navigate towards the port and is vital for avoiding potential hazards.

This system is adopted by countries in the specified regions, facilitating consistent navigation standards among vessels in those waters. Understanding the regional differences and classifications within the IALA system is crucial for safe maritime operations and helps ensure that navigational aids are universally understood among international seafarers.
