Here is a video from the early 90's flying a traction kite from a kayak.
I didn't feel attacked, no worries!
Heeling force on kite boats is small, anyway, that is true.
For considerable upwind performance you will always need an effective way to redirect the wind generated (downwind) pull into something pointed upwind. This is possible through the hulls lateral resistance if it's long and slender(like in hobie cats e.g.), but done better by foils like keel or dagger boards. In my system I can (and do) use asymmetric hydrofoils, even more effective, I can do this because I have different foils for each tack.

I don't know about going ballast free, but eliminating the entire rig portion of a typical sailboat is an interesting concept in a lot of ways. Bridges become a non issue (under power), costs (rigging) potentially go way down, etc.

I do like the idea! Nice

On a bigger boat level, what would you use to reel the thing in? a modified windlass?
As already hinted by Stumble, Skysails (SkySails GmbH*-*Home are offering kite systems for cargo ships, using a launching mast, windlass and control pod. A scaled down system like this would be the way, to power yachts in my opinion(in combination with my rig, of course)

Kibo,

I am not sure exacally what you are trying to patent though. There are hundreds of people attaching kites to kayaks, small catamarans, monohulls, canoes, ect. I would be interested in knowing what specifically you have added though.
Stumble,

I am surprised that you are asking this, as I had tried to and thought to have managed to show quite clearly in the video, how my rig is functioning. It is attached to the bow and provides all the lateral resistance needed for effective sailing in front of the boat, balancing out there. This means, that there is no heeling force transmitted to the boat at all, which is an absolute sensation in sailing. As you can see in the video I am sailing an extremely narrow 32kg(+8kg rig)hull with 21 sqm of sail(=kite), and that is singlehanded and comfortably . This is unheard of in the world of sailing, I think.
While many people have attached kites to small boats, I haven't seen or heard of any one kite sailing a mono hull with ease, and seeming to perform decently upwind.
Skysails, by the way, holding a patent for, summarized, running a watercraft by means of an automatically controlled kite, so if I were to get a patent and someone wanted to (commercially) launch a kite system using my rig and an auto-controlled kite, they needed licenses both from me and from skysails.

On the kayak the blooper reel consists of my hands and arms, which(recovering a wet 21 sqm kite) admittedly isn't the funnier part of it. There is hope, however, that e.g. Skysails, who are offering kite systems for cargo ships already, will eventually come up with a reliable(and thus blooper-less) kite system for yachts.
If this happened, I am convinced, my rig would be the system of choice for yachts, allowing for heeling and ballast free sailing with easily retractable asymmetric foils without even having to compromise on the hull shape.

Great rig Ingo! Super camera work on that video too.

Heeling free kite rig & prototype-video

I have invented a heeling free kite rig which could and would in my opinion change the world of sailing . . .

Power kite kayak sailing fast in Goa - YouTube

. . . if only somebody (Skysails possibly) would come up with a reasonable launching and landing system for yacht-tailored kites

eagerly awaiting your opinions!

Ingo
