During navigation, what does the color green indicate on navigational buoys?

The color green on navigational buoys indicates the starboard side when entering a harbor or navigating a channel. This color code is part of the IALA (International Association of Lighthouse Authorities) system, which provides a standardized method for marking navigable waters. When approaching a harbor, vessels should keep these green buoys on their starboard (right) side.

This is essential for safe navigation, as it helps reduce the risk of collisions and ensures that vessels are following the correct path through the channel. Knowing how to interpret buoy colors is a fundamental aspect of maritime navigation and is critical for operators to maintain safe passage in waters with restricted navigation. Understanding these indicators fosters greater safety and awareness while operating pleasure crafts.

In contrast, other buoy colors carry different meanings, such as red indicating the port side, which would be on the left when entering a harbor. The danger zone and no anchoring area markers also serve specific functions that do not relate to the meaning of green buoys.
