Inflatable and deployed and retrieved from the top of mast automatically? sounds like a hell of a lot more than a side project. Good luck.
Inflatable so that it can re-launched if it crashes. And the mast of the sailboat seems to be the best place to launch/retrieve since it is the tallest point. I was thinking it would be easy to have a pulley system raising it, then releasing when at the top. The tether would then be raised again through the same pulley sistem when it would be time to retrieve it and I would simply pull the tether through the pulley at the top of the mast, brining it it in towards the mast. Or I suppose I could crash land it next to the boat then pull it onboard since it is inflatable.
Look at the kites the container ships use...it’s a foil, not inflatable.
I think the reason SkySails uses a ram-air foil kilte is to have more power and less weight. However if it does come down in the water it would be a pain to re-launch it. Hence this is more useful for this purpose perhaps.

But I was thinking of mounting this on a sailboat as additional power / alternative for the sails.

As for which kite to use, perhaps an ASV Rescue Kite if you can find one. Good luck with launching from the top of the mast.
This is quite awesome! It seems the concept does work and others are using it. The only thing is it is not autonomous and handling it manually would not really work for long trips. Hmm I tried to find an ASV Rescue Kite online but it seems to be quite specialised (probably really expensive).
Wouldn't a light wind kite (e.g. Slingshot RPM 14m) be powerful enough to pull a ship?
