Navigation buoys are floating markers used in waterways to guide boats and ships. They help indicate safe paths, warn of hazards, and provide information about the area. These buoys are often color-coded and may have lights or sounds to enhance visibility, especially at night or in poor weather. Typically made of durable materials, navigation buoys are anchored to the seabed to prevent drifting. They are part of a larger system known as the Aids to Navigation, which includes lighthouses and beacons. This system is essential for maritime safety, helping to prevent accidents and ensure smooth travel on water.
