Apparently grass skis are being used for kiting in Europe.
"Can I use my grass ski for KITING?
YES. In fact, grass ski are ideally suited for kiting – especially if the slope and winds enable the kite to bring the skier back up the slope with very little effort. Since 2003, my grass skis have increasingly been used for kiting and have even opened up a new market for products, recreation and competition with no complaints or negative results to date. Recently, I obtained a kite for myself and enjoyed my first kite ride using my grass ski and enjoyed it immensely. Note that this sport requires much more strength and endurance than just skiing on a snow or grass slope – but additional equipment is available to lighten the load for the kite skier.

What is the GRASS SKI LENGTH recommended for KITING?
The same lengths as recommended for grass slopes:
At the start, slowly start moving. Afterwards you can do larger curves. When using the recommended length for the ski you are well positioned to the slope and will not feel every hole in the surface of the grass. Already with these lengths the ski is steadily moving on the grass."
