I wonder if those kites would be worth using on racing yachts? (as in big racing yachts) Imagine the power they could generate in even 20 knots of wind... wow.
yeah it would be fantastic! i race on a 60ft swan that thing doesn't want to move in light winds so that's a fantastic idea.
how would you go launching it?
do you think it could run like a spinnaker? just strap it to the front of the boat when the winds behind you



you could run it off some kind of Auto Furl system slowly letting out the kite.
i really want to try this now

I have thought the same thing. Even a 12 - 15m kite would work well as you can generate apparent wind by sineing the kite, thereby increasing the "effective" area of the kite.
The hard parts would be:
1. Space to pump on deck. (Problem overcome with a doona)
2. Launching.
3. Unfurling the lines.
I doubt it would be good in a short race scenario given that it would take some time to launch/retrieve, but imagine running out a decent kite on a reach for the Sydney-Hobart!
I'm sure there are some racing rules pertaining to this, otherwise it probably would have been done by now.
There is a company that is developing kite systems for container vessels, and motor yachts. The system seems to use a single line on a winch drum, and the control lines are threaded through the single line. This lets it all be winched in and out without having a kitemare to deal with each time. A computer system controls the trim, and a raising mast structure holds the kite out so that it can catch the wind, before spooling it out.
