What color is a port lateral buoy in IALA Region B?

In the IALA Maritime Buoyage System, the color red signifies a port lateral buoy in Region B. This system is designed to assist mariners in safely navigating maritime channels and markings. A port lateral buoy helps indicate the left side of the channel when approaching from the sea, ensuring that vessels maintain the correct course.

The choice of red for port lateral buoys is standardized internationally in Region B, aligning with navigational rules to create uniformity in maritime navigation. This consistency helps reduce confusion and enhances safety for vessels entering harbors or navigating coastal waters.

Other colors, such as green, blue, or yellow, do not serve as port lateral indicators in this region. Green typically indicates starboard lateral buoys, while blue and yellow are used for other purposes, such as mooring or special marks. This clear differentiation is essential for effective navigation and safety on the water.
