Fun Fact: The term "Nun" not only refers to a woman who is a member of a religious community, but it also has a significance in the realm of maritime navigation. In the world of navigation, a "Nun" is a particular kind of navigational buoy that has a conical shape. They are usually red and are marked with even numbers. These conical buoys, or "Nuns", play a crucial role in safely guiding vessels through potentially hazardous areas. Just like can buoys, they are used to mark the edge of a channel or a specific danger to navigation. Their distinct shape and color make them easily recognizable, thus helping sailors chart their course and avoid accidents. Hence, these Nuns serve as sea guardians, silently guiding and protecting ships on their voyages.
