What is the light characteristic of Wautoma Shoal Buoy?

The light characteristic of the Wautoma Shoal Buoy is identified as Fl G 4s, which indicates a specific flashing green light that occurs every four seconds. This type of lighting is important for navigation as it helps to identify the buoy’s location and distinguish it from others. The "Fl" designation denotes that it is a flashing light, the "G" specifies that the light is green, and "4s" signifies that the light will flash once every four seconds.

Understanding the light characteristics of navigational aids like buoys is crucial for mariners to ensure safe passage through waterways, especially in areas where visibility may be compromised or during nighttime travel. The color of the light also provides information about the buoy's purpose, such as indicating safe passage or marking hazards.
