What identifies a port hand buoy in Region A?

A port hand buoy in Region A is characterized by its distinct red and cylindrical shape. This buoyage system is a part of the IALA Maritime Buoyage System, which is designed to ensure safe navigation by standardizing the colors and shapes of buoys worldwide.

The red color of a port hand buoy indicates that it marks the left side of a channel when entering from the sea, providing a clear visual signal to mariners. The cylindrical shape further helps differentiate it from other types of buoys, such as conical or spherical buoys, which signal different navigational information. Understanding the significance of these characteristics is crucial for mariners in safely navigating waterways and adhering to international buoy marking standards.
