What do you do when you return from open sea and see a red nun buoy?

When returning from open sea and encountering a red nun buoy, you should remember that it marks the starboard side of a channel when entering from the sea. This means you should keep the buoy on your right side as you navigate towards the harbor or port. Additionally, ensure to monitor your navigation equipment and adjust your course accordingly to avoid hazards. Always maintain situational awareness and follow local maritime regulations.
