If you see a white buoy with a blue band what type of buoy is this?

A white buoy with a blue band indicates a special purpose buoy, often used to mark specific areas or provide information about a particular hazard or activity. These buoys can indicate various things, such as designated swimming areas, fish traps, or locations for mooring. The blue band distinguishes them from other types of buoys, which typically have different color patterns and meanings. Always refer to local navigation rules for specific interpretations.
