Which buoy shape is used for a Port Hand Mark in Region B?

In Region B of the IALA Maritime Buoyage System, a Port Hand Mark is identified by a cylindrical buoy shape. This type of buoy is specifically designed to indicate the location of safe water on the port side when approaching from the sea. The cylindrical shape is distinct and easily recognizable, helping to immediately convey navigational information to mariners.

In Region B, the color associated with Port Hand Marks is typically red, which enhances visibility and allows for quick identification among various types of navigational aids. The cylindrical design combined with the specific color coding ensures that mariners have a reliable reference point to maintain proper navigational practices.

Other buoy shapes like conical, pillar, or single sphere represent different navigational marks in the IALA system. Each shape has its own assigned purpose and region, making it critical for navigators to understand these distinctions when operating in varied maritime environments.
