When you see a green lighted buoy with the number 3, it indicates that you are approaching a safe navigational mark. Generally, green buoys are markers for the right side of a channel when returning from sea, so you should keep the buoy to your right as you navigate. This helps ensure you stay in safe waters and avoid hazards. Always refer to your nautical charts and local navigation rules for specific guidance.
