A bell buoy is a type of buoy equipped with a bell that rings due to the motion of the waves. Imagine it as a rhythmic, nautical chime, providing an audible warning to mariners in low visibility. It's a simple yet effective navigational aid, often used to mark hazards or channels. The bell is usually mounted inside the buoy and struck by a pendulum or clapper. Unlike a foghorn, it doesn't require electricity or human operation. It's a reliable and timeless tool for maritime safety.
