Most if not all of the new VHF radios will have DSC mode. This is the button behind the little red door on the front of the unit that you push in an emergency that will send a notice to the Coast guard. If you have set it up properly with a connection to a GPS they will know instantly where you are located and they will know exactly where to send help. Eliminates the "search" in "search and rescue". Not only will they know your location but they will have a description of the boat and more. Unfortunately many people with VHF radios have not set them up properly with an MMSI number.
