Which type of marker indicates the edge of the channel on the starboard side?

The nun buoy is designed specifically to indicate the edge of the channel on the starboard side when you are navigating upstream towards the source of the water. These buoys are typically conical in shape and usually painted in a specific color scheme of red and white. The color red signifies the right side of the channel in many navigational systems, including the IALA (International Association of Lighthouse Authorities) system, which is commonly used in the United States.

When approaching buoys and markers, understanding their colors and shapes is essential for safe navigation. The nun buoy's distinct shape and coloring help boaters easily identify their position relative to the channel boundaries, ensuring that they stay within safe navigational limits.
