Each individual (A-Class) boat seems to need an individual measurement certificate/rating under ISAF SCHRS - anybody have any examples...?

From memory they rate somewhere between 0.98 and 1; I'm at Grafham on Sunday and I'll ask if they have any values from the last Cat open.

Thanks Simon.  A guy responded on the International A-Class forum and said that in Belgium they've standardised on 0.97.

That might be the texel rating, but somewhere around .97/98 is about right IMO.

 

Edit : Just checked the results for last years Cat open at Grafham and a handicap of 1.00 was used - generous IMO....

He was definitely talking about SCHRS.  I think it's right too (unfortunately)...

QUOTE-----

In Belgium the Multihull Association uses the (good old) ISAF SCHRS rating.
For A-class cats we should in theory have a measurement certificate for each boat with, potentially, different ratings for different boats.

However, to simplify things, the Belgian A-Class Association (www.baca.be) has agreed with the Belgian Multihull Association (ISAF associated) whereby all A-cats that are built after the year 2000 have a rating of 97 when participating in Open class regattas.
This was the rating as it came out for my Flyer last year and other boats seem to have same values (some even one number lower and other one number higher).
There is the exception foreseen that if someone thinks he may have a better rating he can always ignore the default by using his individual rating.
The agreement simply avoids measurement hassle for recreational club sailors.

Anyway, if the rating is now 97 or 98, these numbers are pretty irrelevant as they are too low to reflect the real handicap. Especially F18 boats are unbeatable as the latter class rules were defined taking an optimization of the SCHRS handicap rules into account.

Let's see if SCHRS committee do a move like the Texel rating did this year by narrowing even further the gap between A-class and e.g. F18.

Interesting to see that in the (USA-used) Portsmouth handicap system the Aclass has a rating that is higher than F18...

No handicap system will ever be perfect, but some are a bit more imperfect than others! ;

Hey, but I don't feel a single bit sad about this because A-class is just so fun to sail!

OK; this brings on another debate; Should SCHRS be revised as it's plainly been overtaken to some extent.  The Tornado handicap has not changed when the carbon mast was added but talking to sailors they say it has transformed the boat - more power in the light stuff, but more control in the strong suff;  F18's are way faster than they were 5 years ago, but the handicap has not changed. 

Opening the floor for debate..........

There was a 0.01 point penalty for carbon mast that was removed. They
should have kept it.
i think it is still a very valid system

I agree SCHRS is the best we have at the moment; just think it might need a little tweaking.  Planely a new Capricorn is way faster than a Dart Hawk, but the 101 for the F18 was decided when the hawk was around.

Check out www.schrs.com and play with the calculator, For fun i put in the difference between the old mast weight of a Tornado and the new carbon mast (8KGs) it doesnt make a difference to the rating which means for years the tornado could have carried that much less weight from the platform without a penalty. If you take of just 1 more kg it drops to .93 so it rates right on the limit. As for the CMP being removed i think this was a fair decision at the time (when i sailed 5.9s at schrs events) and would be against it being used again, we have (this year) changed to a carbon mast this year and in fact have only just seemed to have got it performing better than our old ally stick and i must say the differences are marginal, Downwind it is quicker in the breezy stuff (20 knots plus) but only because of the less leverage allowing us to push harder. Upwind we have noticed very little difference in all of the ranges, the main differnce we have felt is just the weight difference between the two and of course its nice and easy to rig !!!!!!

Also with the A class if you enter the values into schrs using the available class rules combined with the foil specs from the Bim 18 you get .98 !!!!!!!!!

I put the numbers for a sloop rigged Stealth R in - but as a single-hander.  Came up with 0.92!
