I was playing on a foiled "Sky Ski" board yesterday. The foil on this contraption is about 3' long. It is amazing how the slightest movement will make it jump one way or another. Just taking your hand off the rope to scratch your nose would mean an instant wipeout. My friend is better at this sport and can control it easily, but it does take a long time to master. I like to refer to the control as "touchy-feely". Not sure how different the foils on a cat would be, but I think that I would want a computer doing the thinking for me to maintain control.
