What marking convention is used in IALA A buoyage system?

The IALA A buoyage system, which is commonly used in regions including Europe and Africa, employs the color conventions of red for the starboard side and green for the port side when returning from sea toward port. This means that a vessel heading back into port would keep the red buoys on its starboard (right) side and the green buoys on its port (left) side.

This color scheme is critical for safe navigation, as it helps mariners identify the safe channel and ensure they are following the correct course. Consistency in buoy colors allows for a universally understood system that enhances safety at sea. The use of these colors is well-documented in navigation training and regulations, reinforcing the importance of these conventions for mariners.
