I think the wing mast had a lot to do with the Blades going over while the Hobie 16 stayed upright, of course the lighter weight of the Blade didn't help hold it down, but once the wind changed direction and got to the 'wrong' side of the mast, there is quite a bit of wing area up there for it to act on. It appeared that my boat flew about 30 feet backwards and landed on the starboard bow.
