[quote=samc99us]Interesting John. The only thing you need to update or make a new SCHRS rating is the sail area and mast area. Luff length on the jib and possibly mast height come into play, these are easy things to provide!!
We have been using SCHRS regularly at most events on the East Coast, certainly all that I am involved with hosting! I'll admit though that I preferred the old ratings where the A-Cat, F16 and F18 all rated reasonably close (within 0.002). In actual experience I found this to match reality across a range of conditions. They've since moved the F16 rating into the stratosphere; the F16 now rates 1.028 in doublehanded configuration and 1.041 in singlehanded?? For a boat that touts equal racing 1 up or 2 up that is a huge delta in rating. Further, we had Matt and Gina McDonald on their well tuned Falcon F16 racing against the F18 fleet at Tradewinds a few years ago and they were trading tacks and gybes with the F18 fleet. The boats aren't that dissimilar, and only in the breeze does the length and volume of the F18 makeup for the weight. In flat water light air conditions the F16 is equal and possibly faster than the F18, this is not reflected by the ratings. It also sucks when the fleet falls into a hole and no one is moving but you are sitting there owing time to your competition, but no rating system accounts for that![/quote]
