What is the significance of the color on lateral buoys in IALA Region B?

The color of lateral buoys in IALA Region B plays a crucial role in maritime navigation by indicating the sides of a channel. In this system, colors are used to guide vessels safely through navigable waters, helping to maintain safe passage and avoid hazards. Specifically, buoys on the port side (left when entering from the sea) are colored red and usually marked with even numbers, while buoys on the starboard side (right when entering from the sea) are colored green and typically marked with odd numbers. This color coding assists mariners in identifying the safe navigational path through various waterway configurations, particularly in narrow channels.

Understanding this color scheme is critical for ensuring that vessels remain within designated channels, reducing the risk of collisions or grounding. The correct identification of these buoys aids in situational awareness and helps to navigate confidently towards docks, harbors, and other destinations safely.
