I agree with you guys 100%, I wasn't thinking about a deckload of water. I hadn't considered the bubble concept to work that way before, I'm glad you guys pointed it out.

If I'm ever in a situation (knock on wood) to fill it up with a deckload of water, the danger will have nothing to do with hull design, and everything to do with my stupidity.

That being said, the boat has kept me from swimming many times when I deserved to, and I'm firmly of the school that the operator dictates the safety of the hull design.

I've had that hull out in stupid situations, no question, stupid choices, but it has always responded predictably and kept my feet dry at the very least. All bets are off for the top half.
