A control buoy typically features a cylindrical or conical shape, often brightly colored for visibility, such as orange, yellow, or red. It may have reflective tape or markings to enhance visibility, especially at night. The buoy is equipped with a flag or light on top to indicate its purpose, and it may also include features like a radar reflector or a GPS device for tracking. Overall, its design is intended to be easily identifiable and to withstand harsh marine conditions.
