Funny how all the experts come out who weren't there and really have no idea about the conditions but I can tell you that the dive boat was miles away from the divers and that's not OK. There's a difference between waiting 20 minutes at the surface with the dive boat in the area aware of you and where you are and with the boat being a long ways off and flying in to come and get you after getting a call from another dive boat, especially up further north where the current is stronger. In Boynton or further south divers are typically dropped off in small groups further apart but further north in WPB it is not common to have dive groups far apart for this reason. Who knows how long it would have been or if they would have known where to find them without the call.
