azcat,
I have capsized several times on my boats and always been able to self right without help. The mast tube is sealed so you have a minute to get crew weight out to windward before the boat turtles. We use a righting line on the mast base that hooks into the trap harness and thats all you need. The only exception was once in a violent squall when we blown end over end and dismasted. If you ever do turn turtle on a 10 foot wide boat you would need help to right her. But there is so much more stability you have to really work to capsizie in the first place. 11 feet is enough headroom to fit the trailer with the boat on it.
