I don't know, Jeff. I did the 'Southern Ocean' once. We got pooped more times than I like to think about. Instant draining of the cockpit would have been nice, but I have to tell you, when huge amounts of water head for the lowest spot, they have a lot of force. Being washed out with that water would have been a real possibility. Yeah, we were miserable with ankle deep water a few times, and had to wait for the stuff to drain out, but an open transom on that trip? I wouldn't have gone. Period.
