Hmm ... land yachts with grav lifts ... nice idea ... but it occurs to
me that roll stability could be an issue - a decent push from the wind
on an overhead sail and the craft could potentially roll over so far
as to lose power from the sail.

Possible solutions:

Have the CG centre of lift point well above the vehicle's centre of
balance, so that it self rights.

Have a keel below the vessel to counterbalance. The keel would
probably need to be an aerofoil shape with some control over its angle
of attack.

I'm not sure these possibilities provide a complete solution to the problem.
