I believe a cell phone can be triangulated to find your location.Can VHF do that?Not sure.
That's true if you go through E911. But what if you call the local TowBoat US or SeaTow on your cell? They aren't necessarily set up to read your location. Assuming they are, is that cell phone configured for location services for E911 only or for all calls?

In regards to VHF DF'ing, some boats are set up with that capability. (If you see an array of four equally spaced vertical antennas on a single mount or mast, that's a DF antenna.) For Coast Guard the DF array will pick up both marine VHF transmissions and EPIRB transmitters on 121.5MHz. (Yes, I know they now transmit on 406MHz and include GPS information, but there's still a low power 121.5MHz transmitter for localization once the CG or CAP arrives on scene.)
