It's the Law: On the Water

Diver-Down Flags

• Scuba divers and snorkelers must display a diver-down flag to mark their diving area. The flag must be displayed whenever someone is diving below the surface.
• Vessels should stay as far away from a diver-down flag as is reasonable and prudent for the circumstances. The suggested safe distance from a flag is 100 yards.
