In IALA Region A, what color is used for port lateral buoys?

In IALA Region A, red is the color designated for port lateral buoys. The choice of red for port buoys is integral to the IALA Maritime Buoyage System, as it helps mariners navigate safely by indicating which side of a channel to keep on their approach.

According to the IALA system, when a vessel is navigating upstream or entering a harbor, port side buoys (red) must be kept on the left side of the vessel. The use of red for port lateral buoys assures consistency in navigation aids across regions, contributing to the overall safety and effectiveness of maritime navigation.

This standardized color-coding is a key aspect of maritime buoyage systems, providing a clear and universally understood message to mariners regardless of where they are operating.
