If the green buoy is on top at a junction, which channel is preferred?

When a green buoy is located on top at a junction, it indicates that the preferred channel is to the right. This follows the IALA (International Association of Lighthouse Authorities) buoyage system used in navigational practices. According to this convention, a green buoy marks the edge of the navigable channel and indicates the safest passage for vessels.

In the context of a junction, the presence of the green buoy suggests that boaters should stay to the right side of the buoy when heading upstream or when approaching the junction. This guideline helps ensure safe navigation and minimizes the risk of collisions or grounding in shallow areas by providing clear directions on the preferred route through the channel.

Understanding this system is essential for safe boating practices, especially in areas where navigation aids are critical for determining the best path for travel. Knowing how to interpret buoy colors and positions assists boaters in making informed decisions while on the water.
