Bern,
Don't crack the sheet. Pull it on.
Only when the kite is set and the boat up to speed do you easy the sheet a little to get the main out of its stalled situation.
If you are concerned about the big head not being stalled pull the sheet on real hard just before you jibe but make sure you go through a very small angle. Just enough for the jibe.


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!
