In Region A, which type of buoy is used for a Port Hand Mark?

In Region A of the IALA Maritime Buoyage System, a Port Hand Mark is indicated using a specific type of buoy characterized by its shape and color. The correct choice highlights the use of cylindrical buoys, which are painted red and used to denote a safe passage to the port side when navigating into a harbor or channel.

Cylindrical buoys are typically utilized as navigational aids because their shape is easily recognizable and enhances visibility from a distance and in varying weather conditions. The standardization of buoy shapes and colors in this region helps mariners quickly identify important navigational information and ensures safe vessel passage.

While other types of buoys can indicate various navigational marks, the cylindrical buoy specifically fulfills the requirement for marking port hand channels within Region A. The clarity and consistency in buoy markings and colors are critical for safe navigation and situational awareness on the water.
