We have 12 year old kids drive landyachts at 50mph speeds overhere. You'll be surprised how "brave" they are when they are allowed to start in easy winds and build themselves up to more challenging conditions.

You should see some of the crazy stuff 10 year old kids can do on a motocross track.
Very cool looking boat. What does an opti cost? Price would be a factor as well if it were to be more than a home-built boat.
