Carl: Sounds like the first kites they tested for the "Tornado Sport", giant kites sheeted to the rear beam. I think they tested them on Lake Garda, and it was really scary to race with them as they had no view to leeward..

I wonder what kind of mast rake would be needed to have a tolerable lee helm with these kites tough

Tad: Is your halyard block at the right position, and is it an option to raise it? (without compromising the mast!) Otherwise, perhaps it's time to go shopping..
