A mid-channel buoy that is lighted will show what?

A mid-channel buoy that is lighted typically indicates navigational information, and the correct answer would be that it shows a white light. In general, buoys serve to mark channels, hazards, or provide guidance to vessels, and their lights help convey their purpose during nighttime or low visibility conditions.

The color and characteristics of the light emitted by buoys are standardized to denote specific meanings. Mid-channel buoys often indicate safe passage along the channel, and a white light would signify a navigational aid rather than a regulatory marker associated with color codes that indicate 'port' or 'starboard' sides.

Understanding buoy lighting is crucial for safe navigation, and recognizing that mid-channel buoys display white lights provides clarity on their function. This knowledge helps mariners determine their position in relation to the channel and other navigational aids, ensuring safe passage through potentially treacherous waters.
