Why do divers use 2 dive flags?
Divers’ Flag indicates that scuba divers or snorkelers are operating in the area. Stay well clear of this flag. Many states have specific distance-away requirements from 100 to 300 feet. Check your state regulations.
Rigid Alpha Flag is flown by a vessel engaged in diving operations. This flag does not substitute for the diver-down flag above in states that require the diver-down flag. You will usually see both flags in use. The alpha flag indicates that the vessel is restricted in ability to maneuver, in this case due to the nature of its work.
