I really have no idea but when you bring the two together with a bunch of boys - you get a fun time!
Seth had his boyscout sailboat regatta or something like that - LOL! He painted his boat during scouts and then they got to see who had the fastest boat. I figured out it wasn't so much about the boat as it was about how steady the boy could blow the sail and balance the boat. Seth won his race but did not have the fastest time. I think the reward was in the fun he had though.
