A form of Not Quite Flight in which the flyer stands on top of the object with the relative propulsion mechanisms and control surfaces. While the rider is usually the one in control, all the work is done by whatever he's standing on. The difference between riding a Hover Board and Sky Surfing is that a Hover Board (whatever its shape) is limited in how high above the ground it can go. Despite the name, the flying vehicle in question is not necessarily surfboard-shaped. Sky surfing is Truth in Television, albeit unpowered. Also compare Magic Carpet, Flying Broomstick, Hover Board.
