Just had a look on their web site and there`s a heading " How to launch in off shore wind." Since when is it advisable to go kiting in off shore winds?
Unless you kite on a river, small lake or a serious horse shoe shaped bay that`s not good advice for obvious reasons.

I can see it being usefull for boat launchers.
A bit too fidly for me, but I guess once you get used to it.
