How is the shape of a port hand buoy in Region B described?

In Region B of the IALA (International Association of Lighthouse Authorities) Maritime Buoyage System, a port hand buoy is reliably identified by its cylindrical shape. This design helps mariners easily recognize the buoy's purpose and position in the waterway. The cylindrical buoy stands upright and provides a stable maritime marker.

Cylindrical buoys are widely used because they resist rolling in waves, making them more visible in various weather conditions, which is essential for navigation safety. The uniformity of the cylindrical shape is also effective in ensuring that it is not easily confused with other types of buoys.

The other shapes, such as tapered, pyramidal, and conical, belong to different classifications within buoyage systems or are used for different marking purposes, which can contribute to confusion if mistaken for a port hand buoy. Understanding the distinct characteristics of buoy shapes is crucial for ensuring safe navigation.
