What is the shape of a starboard hand buoy in Region B?

In Region B of the IALA Maritime Buoyage System, a starboard hand buoy has a conical shape. This specific shape is designed to indicate safe passage to the right side of a waterway when approaching from the sea. The conical shape is distinctive and easily recognizable, allowing mariners to quickly identify the buoy's purpose and its indicated side when navigating.

The conical design aids in ensuring visibility and provides a streamlined profile that can reduce water resistance, making it easier for the buoy to remain stable in currents. As mariners become accustomed to the shapes associated with buoyage systems, recognizing a conical starboard hand buoy becomes intuitive, enhancing navigational safety.

Other buoy shapes, while having their unique purposes in different contexts, do not pertain to the identification of a starboard hand buoy in Region B. For example, a cylindrical buoy typically indicates a different purpose or region, and the square and spherical shapes are also used for other buoy categories within the IALA system.
