Which countries typically follow the IALA B buoyage system?

The IALA B buoyage system is primarily used by countries in regions such as America, Japan, Korea, and the Philippines. This system, established by the International Association of Lighthouse Authorities, is characterized by its approach to navigational aids, where specific colors and shapes signal safe passage and hazards in maritime environments.

In the IALA B system, lateral markers typically use red and green colors to indicate port and starboard sides when entering a harbor or navigating channels, respectively. This clear and standardized method is critical for safe navigation, especially in the busy waters surrounding these countries.

Understanding the geographic distribution of buoyage systems is essential for navigators. While other regions mentioned may have different buoyage systems in place, such as the IALA A system primarily in use in most of Europe and Africa, the selected countries notably adhere to IALA B due to their maritime practices and regional shipping needs. This adherence helps ensure consistency and safety in international navigation, particularly for vessels traveling between regions using different systems.
