No that is an important mistake to assume that the boat has to do all of that stuff... First of all, the boat should have a floatline off the stern stretching out a considerable distance from behind the anchored boat. A diver who forgets fins (and even forgets to turn his air on) would simply have to paddle over a few feet, grab the rope and his buddies could haul him in, laugh at him and dump him back in the water. Second, if you didn't put the floatline off the stern, and the diver is in distress, then a rescue swimmer could swim a rope and float to the diver. If that option is not available and there is a significant problem, you do NOT have to pull an anchor up...Just untie the anchor line and go get the diver.(should be able to be done in 60 seconds... running up on an anchor and pulling it, could take 5-8 minutes).... If the guy was simply unable to swim on the surface and could work his dive gear, he would have been located quickly by the boat (or the coast guard) if he really got away. MANY things would have to go wrong for this to happen and for a diver to be lost. Also, why would we assume that the two floaters would be separated. The rescue swimmer would stay with the immobilized diver on the surface. Who knows, but I suspect that the diver was not on the surface for long and probably sunk very soon after entering the water... No way the USCG is that incompetent that they can't locate a drifting diver from a known location and a known time in decent weather conditions....
+1, and it sounds from later reports that they had a safety/floatline off the back of the boat.
My guess is that he was negative, had a medical, or got struck by the boat during the turning operation, otherwise, I'm thinking they would have found him by now.
