Think all wake boats flex as bad as this Mastercraft?

So after watching that video I thought something was funny. look at a picture of how the rear deck is designed on an X-25. Its on hinges, of course it would move a little when the boat is shaking like this. On most boats those rear locker sun pads are just hinged to the side of the boat so when you shake the boat you wouldn't see them moving. Its funny how people come up with some of this stuff.
