Couple of little typos that need ironing out

What do you think Wouter
I think that today wew must commend the SCHRS committee and ISAF for effecting chances to the SCHRS handicap system. It is a commonly accepted fact that alot of sailors and organisation had their pet misgivings about the rating system (and of other rating systems as well) and both the SCHRS committee and ISAF have responded to that. From what I can tell by reading the FAQ pages it seems that SCHRS has now become the most advanced rating system of them all, coming most closely to the wishes of the different parties. That is something that deserves our recognition, especially from hardcore critics like myself. But I want to see the final rating values before making a final judgement. Personally I'm not too worried about the F16 handicaps, we didn't play the handicap rules to get a favourable rating. We actually tuned the specs to have the F16 fit the F18 performance and as such any rating system, irrespectibally of the modifications, is expected to find the two the same performance wise or extremely close to one another (rounding off differences). And I sure that the Spitfire will remain close to these two rivals as well; it is afterall a very fast boat as race results have shown But indeed this is one of those lottery nights were everybody is exited to see where the numbers will fall. Great fun ! Wouter

Great fun ! Wouter Thankyou Wouter. We also have not actually finished yet (not sure we ever will). There was one item that did not make it into the rules this time. It is something that the group will be looking at for the next evolution (March 2008). Edit to add, Wouter, SCHRS now goes to 3DP and so the rounding is no longer an issue for SCHRS, the granuality (we believe) is now at a level where this is no point designing to the rule If I can get hold of the webmaster tonight, the ratings will go up, if not we may have to wait until tomorrow.

Ahh, but these two points are not exactly the same. SCHRS has effectively gotten rid of the rounding off error indeed (hadn't noticed that) but you can still design a boat to "optimize" it to the handicap rule. These two things are different from eachother. When design a boat to best fit the rule you look for mathematical inconsistancies in the way the rating is calculated and try to get more performance in that the will be reflected in the rating number. I know where such "loop holes" exist in both systems (= older SCHRS) but won't disclose these publically. But one is public knowlegde already so I can use that as an example : Removing the jib from a spinnaker boat produced a much larger reduction in the rating then the actually performance decreased. I do suspect however that the new SCHRS system will address this issue as Texel has done a few years back. However, by ending the rounding practise a large portion of the gains that could be had will is lost. Wouter
