Hovercraft racing or should we say, hovercraft flying as it's debatable whether you're actually touching the ground in these high speed personal hovercrafts!
A hovercraft is surprisingly easy to control, with just acceleration and steering to think about, but the real skill is being able to make what is effectively a big motorised fan on an air cushion, go exactly where you want it to. Add to this the element of hovercraft racing, as you compete against the clock and you have an exciting and unusual day for individuals and small groups.
