What does a flashing white light in a buoy typically indicate?

A flashing white light in a buoy typically indicates a specific navigational point or hazard. The purpose of buoys marked with such lights is to enhance visibility and provide navigational information to mariners. The signal can indicate the presence of a designated navigational aid, marking important points like channel entrances, hazards to navigation, or safe water areas.

This type of light ensures that vessels can identify critical navigational information, especially during low visibility conditions such as fog or nighttime. By signaling a specific location, it assists in safe navigation and course-planning for vessels in the area, thus preventing potential accidents or groundings.

Other options could represent various forms of navigational aids but do not match the specific designation that a flashing white light conveys regarding navigational points or hazards.
