What does a keep out buoy look like in the water?

A keep out buoy is typically a large, brightly colored floating device, often marked with bold colors like red or yellow. It may feature a distinctive shape, such as a cylindrical or spherical form, and is usually topped with a flag or light to enhance visibility. These buoys are anchored in water to indicate restricted areas, warning boats and swimmers to stay clear for safety reasons. They are often deployed in locations such as construction zones, hazardous areas, or near underwater obstacles.
