Not sure how long ago that was, but why not just carry a PLB on your person. I have two. I also have an Iridium Extreme Satphone. Makes me feel a lot better on solo backpackng trips. I can just imagine that skipper's dead body halfway to the bottom of the Atlantic Ocean.....meanwhile on the surface with one button press rescues would already know where you are down to several feet. But a captain always goes down with the boat....or some such nonsense.
