What does a white buoy with a blue horizontal band indicate?
Answer
A mooring buoy you may legally tie up to
A white buoy with a blue horizontal band is a mooring buoy, and the Coast Guard says it is the only type of buoy to which mooring is permitted. Most are privately owned or rental buoys, so permission is usually needed before you tie up.
