Paul, Steve is right it is all about being fast when bringing the kite down but with a boat either side of you coming into the bottom mark I like to know my tiller will stay straight while I'm bringing that kite down. The attached pic shows a very simple system that does that. The bungee goes to the tiller which is not in photo. Under normal sailing conditions the bungee is lose. When the kite is being brought down the tension in the downhaul centres the tiller via the bungee.
Regards, Phill
I know that the voices in my head aint real, but they have some pretty good ideas. There is no such thing as a quick fix and I've never had free lunch!
