I have invented a phenomenal kite boat rig and to demonstrate it's enormous potential, attached it to a kayak which I can easily sail with a 21 sqm kite as proven in the following video:

Obviously would work on bigger boats and yachts as well, once big enough kites and appropriate launching and landing systems are developed(which might not happen any time soon, I am well aware of that)

Brilliant and brilliant video.

When do we start manufacture?
 
I have obtain considered if some thing like that may be useful as part of the equipment installed in a life raft that may help to save the stranded by allowing the raft to be sailed rather just relaying on tide drift.
 
Interesting, do you have a full patent granted? it's now public so I hope you have. Not sure it has much commercial value, as it's a very complex toy and ships have proved they don't have heeling issues. But good luck.

We ran speed trials on kite powered cats back in 91, until the whole boat took off!

On the life raft kite subject, I've still got a wwII pilots box kite designed to take an aerial aloft, I carried it with my liferaft when sailing. You can launch it from the raft in quite lite winds.
 
Um, we were mucking about with wingsails in the early 70s... My father built a long canoe(30ft) on foils with a 'T' wingsail. The glider length wing was up on a 'mast' that tilted through the canoe to a foil that balanced the lift. Very like a kite, but much more difficult to make. Potentially very fast, just had a few control problems....
An earlier effort, in the 50s (53,IIRR) he built a tri with a wingsail and foils. The rudders had anhedral to control pitch. It was very fast in a straight line, but going about and pitching in waves caused a few probs. Like pitch-poling!!.
Good luck with your ideas, but there is little new under the sun, just getting it to work! and finding a market.

Self launching kites for cargo ships have been around for some years now:

But your anti-heel device looks ingenious and seems to work very well. How much different is it though from just strapping yourself to the kayak and using the kite in the normal way - like the land based kite buggiers do very effectively?

By just sitting on and being strapped to a kayak one couldn't provide sufficient lateral resistance to be able to sail effectively in decent winds, except for dead downwind or up to maybe 45deg off the downwind direction. Only in light winds, the kite barely flying, beam reaching and sailing slightly upwind would be possible. With my rig I can sail close hauled up to 60deg off the true wind and as my prototype is somehow homemade, low tech and me myself being still a beginner in operating it, even clearly better upwind performance should be possible.

I have applied for international patent protection in Feb 2010 (WO2011095178 (A1)), but it will take at least another year and considerable efforts to get patents granted anywhere.

I actually had yachts in mind, when I developed the idea, however came to the conclusion as well, that the commercial value of my system on a yacht is doubtful, due to thus far non availability of auto-launch- and land-able kites in the right size.
While kite boats in general having much less heel than sailboats, my system has absolutely none. Only this makes it possible to ride a comparatively giant kite on a narrow kayak hull without issues. It might be possible but would require enormous attention, not to capsize, to do this with the same kite and kayak and a dagger board. Plus you needed to steer the boat or develop alternative systems.
