Which buoy is described as come-shaped and ALWAYS RED?

The buoy described as cone-shaped and always red is known as a nun buoy. These buoys are part of the lateral system of marking navigable waters, where the color and shape convey specific information to boaters. Nun buoys are typically used to mark the right side of the channel when approaching from seaward, which is why their distinct red color is significant.

The cone shape of the nun buoy helps mariners easily identify it, especially in situations where visibility may be limited. Additionally, the red color is integral to this identification, as it conforms to established navigation rules. Knowing the appearance and function of nun buoys is crucial for safe navigation on waterways.
