The hoovercraft is a planing boat for use
on the road.
At slow speeds, it travels on wheels. On
the open highway, though, the sluices
throttle are opened. The sluices
a vast amount of water from the mid-
point of the craft. The rear portion of the
hull planes on this
cushion of water, like
any regular speedboat. Aft of the hull, a
250hp vacuum cleaner retrieves the
directing it through a filter unit and back
to the mid-ship sluice gates. The overall
effect is of a speedboat scudding along
the motorway on its own personal
No longer need you huddle like the
millions of your fellow travellers, seated
behind a wheel in a glass coccoon. In
your hoovercraft, you can stand manfully
in the cockpit, hand on the tiller, a
peaked cap snugly on your head, and a
pipe clamped firmly between your teeth.
As a bonus, the road is left spotlessly

No, this just will not do. At slow speeds, it should be a sailboat. Have a collapsible ring on the perimeter (an above-ground pool with the road surface forming the bottom), filled with water. As water flows downward, recycle it with the pumps, just enough to leave a cushion of water. Raise the mast, sail on.
||... wheels?! Hoover must be sucking in his grave.
||The sailboat mode is only available at an
extra cost. The problem is that fully-
bouyant craft requires a good depth of
water under all of its hull, whereas a
planing craft needs only a shallow pool at
the rear. You have to consider the
practicalities when you're dealing with
things like this.
||You're right. Sorry, I've been impractical all day.
||It should be more specific and convoluted.
||Filtering out the return water with a screen, and returning it to the road is what happpens when the screen is full. It returns, not in the pumped water (for pumping the super dirty water would be unwise), but after it is produced in a cup next to the driver's seat, whereby he/she proceeds to take the rubble and throw it overboard.
