What is the light rhythm of the Starboard Hand Mark in Region B?

In the IALA Maritime Buoyage System, the light rhythm of the Starboard Hand Mark in Region B is characterized by a specific flashing pattern that aids mariners in identifying the mark during navigation. The correct light rhythm is “Flashing (2 + 1).”

This rhythm indicates that the light will flash twice, followed by a longer period of darkness before it flashes once. The combination of flashes and the sequence is specifically designed to create a unique signal for the Starboard Hand Mark, which helps differentiate it from other navigational aids.

Mariners can recognize this rhythm in the context of vicinity to the buoy, confirming that they are on the correct side of the channel when navigating. The specific pattern of two quick flashes followed by a single flash is standardized for consistency and safety in navigation, allowing vessels to easily identify their position relative to the buoy.

Other light rhythms, such as fixed lights or other flashing patterns, serve different navigational purposes and indicate different types of marks, but the “Flashing (2 + 1)” is what clearly identifies the Starboard Hand Mark in Region B. This standardization is crucial for maritime safety, ensuring that all vessels understand and correctly interpret the signals provided by navigational aids.
