I interpreted the issue as being one of those flush portholes along the topsides that one sees sometimes, and that the seas were rough enough that they (presumably) knocked it open and splashed up against it often enough to fill the boat. I came to this conclusion from the following in the article:
"Cook [nb: owner] said Peer [USCG Rescue Swimmer] helped them bail, even thinking to plug the gaping hole in the vessel with pillows, and things were improving because the seas had calmed."
A pillow is too big for a throughhull, but about right for an actual porthole. Further, the boat did not sink after the helicopter left, since they are apparently coordinating salvage for the vessel, which would suggest that whatever the rescue swimmer did in plugging the hole, plus possibly calmer seas, was enough, making me suspect the opening was above the waterline:
CLEARWATER, Fla. — A Coast Guard Air Station Clearwater MH-60 Jayhawk helicopter aircrew rescued two people and their dog, Saturday, about 90 miles off Hernando Beach after their sailboat became

The thing I noticed most, though, was that these two people had been bailing nonstop for a long time, to the point one looked like they were having "a heart attack", and they would have eventually sunk if the USCG had not shown up... and they
never thought to plug the hole with a pillow or something? While they were on the way to sinking!? How is that sequence even possible?
Which brings me to
@peaman 's comment, which I heartily agree with -- these people had no training. I remember when I was _taught_ what to do if water was coming in, and it included, after finding the source, "plugging the hole" (along with notifying USCG of course). A sock was suggested as about right to jam in a broken throughhull, and I distinctly remember thinking that I might not have come up with that under pressure -- I could have sat there stupidly wishing I had a spare fitting or something. It sounds silly, but especially in stressful situations, having already been pointed in the right direction can help. Which brings me back to 'training.' Having encountered in real life people like Peaman describes, I am always surprised at how resistant otherwise intelligent and educated people can be to the suggestion that training is a good idea (and usually cheaper than learning the hard way).
In the spirit of learning something from this, though:
If the water is rising, and the electronics shorting (I also agree with Peaman there), what is the best policy? The battery switch (as the water gets high enough), I assume -- it's what I would have reached for -- but my boat would still be easily afloat with even the battery terminals themselves underwater... at only 12V, I would think submerging the batteries would not be an issue -- at worst, you heat water, of which you already have plenty aboard. Am I missing something one should know to do?
