Note the settings in a little booklet so the next time you switch setup you can quickly tune the rig to reflect it.
Personally, I get from the reports that your trim setting were completely off. In 17-20 knots you should really be tracking with the US I-20's (sailed by comparable crews) if not slowly overtaking them. They have to shed too much power in those winds. Again, in those conditions your competition should be the F18's upwind. Seems Chris and Nicole were on the mark there.
Tom, what suit of sails do you have, brandname ?
With the Glasers your 335 lbs should be very near to optimial 2-up weight. If you still got Ullman then (lots) less will be better !
