A buoy is a floating object anchored to the seabed that acts as a vital navigational signboard, hazard marker, and data collector on the water. From the simple life rings tossed to a struggling swimmer to high-tech, sensor-laden oceanographic hulls, buoys are the unsung heroes of maritime safety. They translate an unpredictable, featureless ocean into a structured and predictable environment, ultimately preventing shipwrecks, guiding rescuers, and providing early warnings for deadly natural disasters.
