I've only been turtled twice as well (one after the other after I forgot to release the main sheet before righting the boat from turtle the first time! ). That was on my 6.0 and it popped right back up like a cork both times. We got on the corner of the boat that was farthest downwind and sat there for a minute or so. The first time we sat on the stern and the second time it was the bow - worked fine both times.
