What type of buoy indicates a Starboard Hand Mark in Region A?

In the IALA Maritime Buoyage System, a Starboard Hand Mark is indicated by a buoy that is conical in shape. This design is specifically utilized in Region A, which includes European and certain African and Asian waters. The conical buoy is painted green and typically displays a conical top, making it easily distinguishable from other navigational aids.

The significance of the conical shape lies in its recognition and association with guiding vessels to navigate safely. When a ship is traveling in the direction of the buoy, this buoy should be kept on the starboard (right) side, indicating safe waters ahead. This visual cue helps mariners to determine safe passage and avoid hazards.
