What is the primary purpose of a buoy?

The primary purpose of a buoy is to mark navigation channels and indicate hazards or safe waters. Buoys play a crucial role in maritime navigation by helping vessels determine safe passages and avoiding dangerous areas such as rocks, shallow waters, and other navigational hazards. They are strategically placed in various locations to guide mariners safely through waters, ensuring they can navigate efficiently and prevent accidents.

While some might think that buoys could serve purposes like providing spots for fishermen or acting as decorations, these functions are secondary or incidental compared to their main role in navigation and safety. Additionally, buoys are not used to anchor ships securely in place, as their primary design does not include providing a stationary hold for vessels.
