It may not be a Back to the Future hoverboard, but Hammacher Schlemmer's personal hovercraft can carry 600 lbs. while attaining altitudes of 20 feet and speeds of 70 mph over land or water. It also holds enough fuel to travel 160 miles at a time.
From the Hammacher Schlemmer catalog:
Operating in fresh- or saltwater and up to 30% inclines over sand, mud, grass, swamp, desert, ice, and snow, its wings and horizontal elevator enable pilots to simply hop over water- or land-based obstacles up to 20'-high unsurmountable to a typical hovercraft. A joystick controls three vertical rudders and the elevator, a twist friction-lock throttle controls forward speed, and a variable drive system controls the lift fan for hovering.
Sounds like a pretty solid deal, if you happen to have a spare $190,000 burning a hole in your pocket.
