The RC did what they were supposed to do - anyone not finished within the time limit gets DNF. If they'd finished people on the course, they'd've been subject to protest. The way I remember it being worded was that they COULD finish folks on the course in the interest of getting in more races - not so that people not finishing within the time limit could have a lower score. And they weren't OBLIGATED to finish people on the course.

I agree with Mike that the SIs could be changed in the future to make it less of a hit if you can't get across the line in a dying breeze, but for that particular race, the RC acted properly and within the rules. SIs aren't flexible once you're on the water. Don't knock 'em. That's boat racin'.
