Diveflag - a universally understandable flag which warns of the presence of a diver down or snorkelers in
the water.
Nearly every diver has either had personal experience or heard stories about a near miss with a boat who’s skipper did not understand the meaning of either the Alpha or the red/white dive flag which was being flown. Major associations accept the dive flags in existence today are unlikely to be understood by anyone except divers. There is no legal requirement to do so.
