What is the shape of a nun buoy?

A nun buoy is characterized by its conical shape, which is designed to stand out and be easily recognized by mariners. The conical shape allows the buoy to be stable in water and provides a reduces wind resistance. This design is also complemented by its coloring, typically red with a pointed top, which serves as a visual cue for navigation. This specific shape and color help differentiate nun buoys from other types of navigational aids, such as can buoys, which are typically cylindrical. The conical shape is significant in aiding vessel navigation by clearly marking channels and indicating safe passage or hazards.
