Not sure what you mean Ron????

All the tires are ribbed. Except for the smooth ones on the trailer with the girls in.
On my Sysmic S2 (I used in Yeppoon) they are "Midi XLS" 180mm wide and 430mm high on Sysmic 4" x 8" wide rims.
Not sure the mast step would work Paul.
It would need to be much further back, as with more power on a yacht there is increasing down pressure.
On a kite buggy, more power is less traction. So the centre off effort becomes really critical. I mucked about for a few hours adjusting the buggy to get all 3 wheels to break loose together. (Seat forward, swan neck out, foot pegs in a good position etc.)
It won't run the same with another person in it. Which is handy as no one steals your buggy when you're not looking as it won't handle well.
Will give it some thought though.
Cheers
