What does a white buoy with a black letter “A” designate?

A white buoy displaying a black letter "A" indicates an exclusion zone or a swimming area. This designation is crucial for maintaining safety on the water, as it alerts boaters to areas where their presence may interfere with swimming activities or where certain restrictions are in place. Exclusion zones are typically designated to keep boats away from areas that may be hazardous to swimmers or to protect certain marine environments.

By identifying such buoys, boat operators can navigate safely, ensuring both the safety of swimmers and compliance with local maritime laws. Understanding buoy markers is fundamental for responsible boating practices, and recognizing the significance of this particular buoy helps prevent accidents and enhances the safety of all waterway users.
