There are numerous possible reasons why kitesurfing isn't considered to be classified as sailing:
- the sail is not attached to the hull, so it isn't a "craft"
- sailing in 10cm has been given the term "liquid ice" for a reason; you get a change in drag and lift, when the water is very shallow. Compare this with world-class swimming and why the pools are a least a certain depth; you swim faster in shallow water.
- Under some scenarios, the kite flies at a different speed to the hull (and sailor); when this occurs, you need to measure average speed of both pieces of gear.
- on an official course, the distance from board to kite (along the path of travel) changes significantly; one could argue that such a craft would be required to have the same length (along the path of travel) at the start and finish lines, otherwise there is an unfair advantage (relates to previous point of different speeds).
Of course this all depends on your point of view...
The water depth is an interesting one - strictly speaking, ice-sailing is really just water-sailing where the water layer is extremely thin, and as it turns out makes an extremely slippery layer. Since ice-sailing is really a sail-powered craft on a water layer, they already go real-fast.
One could argue that windsurfing also runs in "too shallow" water, but the reality is that most sailors arn't crazy enough to sail in 20cm of water, just in case they catapult head-first.
