When I've heard a distress call to Baltimore the first question from the CG is "is everyone wearing a PFD?" Never heard a request for call sign or registration number. Proper protocol on VHF is honored mostly in the breach.
Really? So how does the CG identify which vessel they are directing the comments/questions to? They simply go back and forth like two bass fisherman on 68? What happens when a third or forth vessel gets involved? Hard to believe.
