I'm not a fan of it, I think such a craft needs 3 to 4 points of lift not two, and gimbal fans are always a good idea.

If you regard a helicopter main rotor as a single gimbal that would be a mistake, the control of it is much more complex, and hovercraft are a different animal.

So the above is not "aerodynamic?

It uses air to reduce friction and therefore is more fuel efficient than a boat going though water 100 times denser than air. If aerodynamics is all about making a craft more fuel efficient and or faster with the less HP, then this is the ultimate machine. Airboats cannot touch a hovercraft in the efficiency category although modern slippery plastics can narrow things up a bit under the right conditions.

Air is a good lubricant, just saying.

Oh, and don't go trying to replicate that illustration above, a hovercraft would just slide down the crown in the road and aim you into the curb, or a tree or a parked car.
