Dear all, It seems a shame to drop this subject, I’ve got a question on this, I’ve got a A-class racing nationally under SCHRS and we get a lot of heat from other classes when I mention that the A does not rate well under SCHRS. Just to give you a bit of background on this, I used to race F18’s and have been a national champ a number of times in F18/ Tiger class before I moved across to the A. But since getting the A a few years back along with some other good sailors any A just cannot get to the top of the fleet at events when I know if I was back in my Tiger I would easily have been up there. The conditions have to be just perfect ( very light airs, flat water, very short courses) before an A-class can start to rate to SCHRS.
Thus my question is if I believe all the chat about that SCHRS is rating the A perfectly and I’m crap, why is it that the A-class is getting time under PY? For example in Australia the A and F18 race under Victoria Yardstick ( I know nothing about the Aus racing so I may be wrong on this, please correct me if need be) and it give the A time on the water, and that nation has some of the world’s best F18 and A class sailors racing against each other and there is no chat on the web complaining about their PY system. Am I missing something fundamental here?

Rob,
As stated below, under the AUS and US PY, the A has a very handy rating as it does not get raced much.
The A rates about the same as the F16 and they do OK against us on Handicap, and against other boat.
Chris was Flying at the Grafham open and that was hardly suitable wind for single handers such as the A.
(Remember each A needs to be measured to have a PUKKA SCHRS as the A class rules do NOT COUNTROL the same things as the SCHRS model uses to rate - Mast height and thus mainsail luff length being the main one).
The A DOES exel in the lighter stuff and so WILL struggle in the big stuff with such a high aspect ratio rig.
To answer Codblow (again) SCHRS has to make an assumption about crew weight, thus we use the worldwide average that is 75kg for an adult. Some will be lighter, some will be more.
We CANNOT implement a "actual crew weight" element as this would:
A, mean at EVERY EVENT and every race you have to weigh EVERYONE and re-calc the rating - it would be impossible.
B, Protests on weight of the crew anyone? - another nightmare
C, Inaccurate or differing scales? Had a big curry the night before?
We will
not be implementing a "Crew weight" based rating element. End of story.
