If you see a buoy with red on top, which direction is the preferred channel?

When encountering a buoy with red on top, it indicates that you are approaching a preferred channel marked for navigation. Specifically, in the context of the U.S. Aids to Navigation System, a buoy with red at the top signifies that the preferred channel is to your left when you are facing upstream or towards the flow of the water.

This means that boaters should stay to the left side of such a buoy as they navigate. The marking system is designed to assist boaters in safely maneuvering through channels, especially in areas where navigation can be challenging.

In contrast, buoys that are green in color or have green on top would indicate that the preferred channel is to the right. Thus, remembering the color conventions is essential for safe boating, ensuring that navigational routes are followed correctly. Understanding these signals is key to preventing accidents and ensuring a smooth journey on waterways.
