I watched it on Tivo and then read this thread before responding. I'd say all-in-all, the two are really lucky to have made it out not only alive, but in one piece. But I'm pretty unforgiving of their stupidity. From start to finish during the show, I kept saying (out loud, I might add) "How can they be so stupid?"

Let's see, set out on the open sea in a craft not even CLOSE to recommended. Set out in it overweight and seemingly not so well prepared. When the storm comes, jettison your water supply which floats instead of roping it off and dragging it?

Ugh.. okay, then the whole shelter thing, if you have the rigging, why not make an A frame tent and let the breeze blow through and dig into the beach? Set up a solar still or a makeshift still by boiling water in a piece of the catamaran or maybe in a bowl fashioned our of the cactus? They had an entire pontoon and a decent fixed blade knife. They had firewood and matches.

It just went on and on. Obviously it's easy to be the armchair quarterback and I'm sure that I wouldn't want to see anyone perish like that, but it seems to me that they were awful flippant and not really prepared. On top of that they made some pretty bad decisions and didn't utilize the opportunities they had.

I'd say, sometimes it pays to be lucky when you aren't prepared. Oh yeah, maybe one of the Parameds or Docs on here could clarify something. IIRC, drinking too much water at once when severely dehydrated can kill. Something about thinning the blood too quickly or maybe raising the blood pressure?
