What is a navigation buoy used for?

A navigation buoy is primarily used to mark safe waterways, indicate directions, and highlight hazards for boaters. These buoys are strategically placed in waterways to ensure that vessels can navigate safely and to avoid dangerous areas such as shallow waters, submerged rocks, or other obstacles. They come in various colors and shapes, each conveying specific information about the waterway and the safe path for boats. For example, red buoys typically indicate the right side of a channel when returning from sea, while green buoys mark the left side.

In contrast, the other options do not accurately represent the primary function of navigation buoys. While weather changes can affect boating conditions, buoys are not designed specifically to indicate weather. They also do not serve as fishing spots, nor are they intended solely for recreational purposes. Instead, their fundamental purpose is to serve as navigational aids that enhance safety for all waterway users.
