When a boater sees this buoy they can be guided by it to receive information. The message is displayed using lettering or symbols and is contained within the orange square.
This buoy can be distinguished by being white in color and having an orange open-faced square on opposite sides. The buoy also features two horizontal bands, one above and one below the square. If the information buoy has a light, it will be yellow and flash every four seconds.
