No problem, Roger. I enjoyed the analysis. Very
informative. Even when I don't do all the ship shape
stuff; I always adjust sail shape. I useally don't
ever get passed by anything lest than a 28 footer and
I have even been known to give Bill a run for his
money in his 28 foot Hunter. Of course, all ship
shape stuff must be done to do that.
