What does a green buoy signify in navigation?

A green buoy in navigation signifies the starboard hand in the IALA Maritime Buoyage System. This means that when entering a harbor or navigating a channel from seaward, a green buoy should be kept to the right side of the vessel. The use of green buoys indicates the correct side on which mariners should pass, aiding in the safe navigation of vessels. The color green is universally recognized in maritime contexts as a marker for navigation, associating it with the right-hand side.

The significance of green buoys extends to ensuring that navigators have a clear understanding of which side to navigate when approaching hazards or navigating narrow channels. Proper recognition of these buoy colors contributes to overall safety at sea by helping avoid accidents and grounding. This standardized system is critical in maritime navigation since it offers a universally understood set of signals designed to guide mariners in their journeys, enhancing safety and efficiency.

In contrast, other buoy types have different meanings; for instance, a red buoy would be associated with the port hand and should be kept on the left when entering a channel. Therefore, recognizing the meaning of the green buoy is crucial for maintaining proper navigation protocols in maritime operations.
