What is the shape of a nun buoy?

The shape of a nun buoy is conical. This type of buoy is designed to mark the starboard side of a channel when returning from seaward, and its distinctive shape allows it to be easily identified by mariners. The conical shape provides stability in the water, ensuring that the buoy remains upright and visible, even in rough conditions.

The conical design also emphasizes its purpose; typically, nun buoys are painted red and display a specific number or letter that corresponds with navigation charts. This visual identification aids in safe navigation by indicating the correct side of a channel. The other shapes mentioned, such as cylindrical, pyramid, and flat, do not represent the standard shape associated with nun buoys, which is pivotal in maritime navigation safety.
