My cousin's husband had an olympic-class Tempest, and EVERYTHING was adjustable, some on the fly and some took some foresight. Crewing with him was an adventure each and every time, since he loved skating the hairy edge to see what that boat could do. We outran lots of boats with IC engines, but we also had to run with the wind or tack against it, giving the "stinkpots" the advantage. I wouldn't mind crewing on the adrenaline-pumped "lobster boats" that win races here, but you can't downplay the pull off a well-rigged light sailer - it's compelling. I used to own a little lateen-rigged sailboat that would pound the tar out of the AMF boats - steer close to the winds, mind the timing of the waves, and ease on ahead.
