While we wait for the formal publication of the details of the Sailjuice Global Warm-up Series it may interest folks to hear about the revisions in handicaps which will be used as the forthcoming events. All the clubs involved have been meeting and sharing/analyzing data from the previous events and also from club race results and there is something like 95% agreement on the values to be used at the clubs. A few exceptions remain and clubs will use different values for these classes but these are only a small minority and it is hoped that the clubs can converge on these classes for 2013.
With the postponement of the Draycote Dash, the Grafham Grand Prix which takes place on Monday 2 January will be the first event of the series.
The following are some of the big positive handicap movements for the Grafham Grand Prix
Class RYA PN GGP Handicap Change
Laser 1082 1118 36
Laser Radial 1106 1140 34
Yeoman 1108 1140 32
Laser 4.7 1175 1205 30
Laser Pico 1260 1280 20
Comet Trio 1085 1100 15
Wayfarer 1101 1115 14
Enterprise 1117 1130 13
Topaz Vibe 1185 1195 10
Streaker 1162 1172 10
Solo 1153 1163 10
Laser 2000 1090 1100 10
Miracle 1190 1195 5
OK 1109 1114 5
Supernova 1065 1070 5
 
Clearly some other classes which frequently win silverware have negative changes in their handicaps. These will be apparent to those who study the NOR................... Wink
 
We hope that the changes are seen to be fair and also that we can convince some classes (like the Laser) who have previously seldom won anything to take part and to travel to these events.
Time will tell, meanwhile we hope that the official Sailjuice information will soon available.
Regards
Bob

Should have kept my laser! Thats a ridiculous handicap! I was thinking this series might be a fun one to go have a go at this year but I dont think i will now looking at handicaps like that, I would be pretty angry if i made the effort to travel to them and some less than average club laser sailor turned up in his knackered old shed of a laser and sailed around aimlessly all day and walked away with the prizes.

Well thank god that it's not competing and enjoyment of the event that's paramount!

I'm trying to arrange for my nippers to go in their 4.7s, and I may actually get a race for a change by taking a club laser (see if Dad's still got it).

I'm wrong there is some info on the Sailjuice website.
Here is the link to the promotion of the series on the Sailjuice website.

Laser handicaps are a big problem from the data I have. You need that sort of figure or even higher if front of fleet Lasers are going to be in with similar chance of winning compared to equal ability sailors in other classes, but at that sort of figure mid fleet Lasers are very advantaged compared to mid fleet sailors in other classes.

1118, for instance, would have brought 3 Lasers into the top 5 of my reservoir clubs biggest handicap series (60 boats and 16 Lasers entered), and 5 into the top 10, but only three of the 17 races would have been won by Lasers, the majority of wins going to RS200s, RS600s and Solos.

Normally we run Lasers on 1088, which is statistically well founded for the majority of our fleet, but doen't in my opinion leave the top of the fleet winning as many races as they ought. At 1088 Lasers one one race, with one boat in the top 5 and three in the top 10.

So the problem is that top Laser sailors are apparently unable to get as far in front of the maim body of their class as top sailors in every other fleet I've had enough data to analyse, both slower and faster, easier and more difficult to sail. This means its impossible to handicap both the mid and the front of the Laser fleet "fairly". You just have to try and achieve a balance I guess. On the data I have I don't regard this as a gift handicap for the front of fleet Laser sailors: I think it gives them a reasonably fair chance compared to top sailors from other classes, although doubtless events could prove me wrong.

I wonder if the Challenger handicap will have been affected?  Wink  I was thinking of using one for Grafham, especially if it's blowing!  I am hoping to take Jaws the Megabyte to the other events with the PY they use at Shoreham - 1074 (I'm sure someone will correct me if I'm wrong) - which I'm hoping will be accepted.  I don't care if it's not competitive, girls just wanna have fun and all that...Having not sailed or raced in two years I'll just be glad to be on the water Tongue
the same, but different...

i think that those handi caps are silly, one thing that has not been taken into account is the quality of the sailors in the classes. i know people are going to say the lasers have the best sailors in the world in them, which is right but at a uk club level certainly at our club they are far from to be polite. i think changing the handi cap system to make it fairer is rubbish i know at my club that they were looking at changing the handi caps and all it was going to do, was mean people that sail boats that arent normally raced by people that are that good at racing where going to start wining most of the handi cap races this was apparently to make it fair what would have been better is to organise some training and helms and crew swapping to get every one up to speed to improve the level in the club

I believe that the SJ handicaps are being based on the work being done by some of the large inland clubs that have put a lot of effort into this. To pick up on Jim's point, I think I'm right in saying that these yardsticks are based on the different classes having an equal chance of winning, rather than coming mid fleet as the standard system uses. IMO that is much more sensible, especially at prestigious events where sailors are, after all, there to win. The numbers for the development classes are lower than standard to account for the standard system always lagging behind. Andy Rice wrote a piece in Y&Y last month about it.

That laser Hcap looks great to me. A top sailor could perhaps do ok on that in 5 to 10 kts, but will still get cuffed outside that range. In some classes the disparity between the top sailors and the average(as implicit in py) is very different.
I completely agree with the approach that the best sailors should all finish at the same time in a pursuit race class windspeed specialities notwithstanding.
This obviously raises the spectre of which classes have the best sailors.
When are the rya py group going to use the last 20 year's advances in genetics to clone Nick Craig (possibly with some scaling) to finally close this problem off for once and for all.

For most classes that's the same thing. The speed difference between first and last seems to be suprisingly similar across different classes in the data I've crunched .The thing about it being wider for more extreme boats may be something of a myth, certainly on data I've seen.

The trouble with trying to base handicaps on race winners is that you have, by definition, very little data. I'd love to know how to work out why Lasers have this peculiar statistical quirk in the performance distribution curve.
