Good info. That is not the usual USCG response to a legit MayDay. In my experience they sent a ship quickly and without too many questions. (the mounds of paperwork came later). Good point about carrying credit cards and ID in ditch bag. In modern life priorities are not always what you would think. A boat can sink anywhere at anytime, (and then become a dangerous unmarked obstruction itself). Not to mention massive steel
crab traps with an old blackened algea covered float in the middle of the channel.
