What color and shape are used for a "starboard hand buoy" in IALA Region A?

In the IALA Maritime Buoyage System, a starboard hand buoy is used to indicate the right side of a navigable channel as one approaches from seaward. In IALA Region A specifically, this type of buoy is marked with a green color and has a can-shaped design. The green color is essential as it signifies that vessels should keep the buoy on their starboard (right) side when navigating the channel, particularly when coming from the open sea.

The can shape is distinct and easily recognizable, aiding in the buoy's identification during navigation, especially in various weather conditions or times of low visibility. Understanding these specifications is crucial for safe maritime navigation and helps in understanding the broader IALA buoyage system, where colors and shapes are fundamentally tied to the roles that these buoys play in ensuring safe passage through channels and along coastlines.
