Buoy
A buoy is a floating device that is anchored to the seabed and used for marking a specific location or providing navigational assistance to ships and boats. Buoys can be used to indicate the presence of underwater hazards, such as rocks or shoals, or to mark the location of channels, shipping lanes, or other navigational aids. They can also be used to provide information about weather conditions, water depth, and other important factors that can affect navigation. Buoys come in a variety of shapes and sizes, and can be made from a range of materials, including plastic, metal, and concrete. They are typically painted in bright colors and may be fitted with lights, horns, or other signaling devices to make them more visible to passing vessels.
