Unlike car drivers on land, navigators at sea have no road signs to indicate speed limits, dangers, or routes. Navigational buoys are floating objects anchored to the bottom that serve as aids to navigation. Their distinctive shapes, colors, and other markings provide information indicating their purpose and how to navigate around them.

Structure And Appearance:

The bell buoy is mainly composed of a buoy body and a bell. The buoy body is usually a device with sufficient buoyancy, generally round or cylindrical, and the outer shell material is mostly metal (such as steel) or high-strength plastic. Its color is relatively bright, usually red, green, or yellow, so that it can be easily identified by ships on the water surface.

The bell is usually installed in the upper structure of the buoy body, and the size of the bell varies depending on the purpose and design requirements of the buoy. The diameter of the bell on some bell buoys may be only a few dozen centimeters, while the diameter of the bell on bell buoys used in large waterways may reach about one meter.

Important Role in the Voyage:

The bell buoy is swaying with the flow of seawater and emits a bell sound, which can be transmitted within a certain range, providing an auditory signal for ships sailing on the sea. 

For example, on foggy days or at night when visibility is low, the crew cannot rely on vision to identify the position of the buoy. At this time, the bell sound can help them determine the position of the buoy, thereby preventing the ship from colliding with the buoy. At the same time, the buoy can also be used to determine whether the ship has deviated from the course.
