Towing a dive flag is not practical here at many dive sites, due to depth, current, kelp, or any number of other reasons. Technically it's required ... but virtually nobody ever does it. The law is not enforced ... nor is the one requiring boaters to maintain a distance from a dive flag those few times when they are used. I've before told the tale of video'ing a 40-foot boat literally running over a dive flag in 20 feet of water, while an OW class was being conducted directly underneath it. When I offered the video to the Harbor Patrol, the officer told me that unless someone was injured, there's nothing they could do about it. If they offer no benefit, why use one?
May be with the use of an Alpha flag, the USCG would not be as understanding as the Harbor Patrol.
