A buoy is a floating object in the water that marks a specific location or provides guidance and warning to boats and ships. It is usually anchored to the sea bottom with a chain and designed to withstand strong currents and winds. Buoys can be bright colored, numbered, have lights, bells, or horns, and are used to indicate channels, navigational hazards, and areas where swimming or fishing is allowed or prohibited. Buoys are essential for safe navigation and should be taken into consideration by boaters and sailors.
