Land yachts will run on a number of surfaces depending on the tyres they roll on.
For soft sand you would require wider, low pressure tyres but this also means more friction and slower speeds.
I run along the beach on hard packed sand after the tide has gone out and I run on skinny tyres with small contact patches - less friction - faster speeds.
On my class 5 the rear wheels are standard Kawasaki motor bike front wheels and tyres while the front wheel is a standard BMX 16" wheel and tyre with modified hubs to take high speed roller bearings.
My home made job runs on two modified 'twist-and-go' scooter wheels with a steel cone welded to the front face to take the tremendous side loads generated by the sail for rears with smooth tread tyres.
The front wheel is a kiddies 12" 5 spoke plastic wheel and tyre again with modified hubs to take high speed roller bearings and standard knobbly tyre for better grip on turns.
But you don’t have to go ''pell mell'' for all your worth.
With the sail set right, you can cruise along the waters edge peacefully up and down the beach at sunset on a gentle on-shore or off-shore breeze all evening with only the sound of your tyres crunching over seashells and splashing through the edge of the surf at a more sedate speed.
There are guys your side of the pond who are into this sport big time.
There are guys who I have some involvement with that use vertical airfoil wings instead of cloth and terylene sails over your way!
This is wingnut 1
And the current design, ST 49 class
And more sophisticated ones like this aluminium bodied job

These fellas build their own ships out of plywood and trailer wheels, check out the free plans and advice there
You lot in the US have vast deserts to tear up, something us UK guys envy as the UK is distinctly lacking in deserts!
These things are just as fast if not faster!
Forgot to mention that there are some superb onboard and spectator videos of these craft on their website.
