Buoys are floating devices used in bodies of water to mark channels, hazards, or provide navigational information to ships and boats. They typically have distinctive shapes, colors, and markings to help sailors understand their meaning and location. Buoys play a critical role in maritime safety and navigation.
Nun buoys are typically marked with a single red mark, while can buoys are marked with a single green mark. These marks help to indicate the direction in which boats should pass the buoy in order to navigate safely through the waterway.
