hi chris.
thanks again for the offer of help.

as the moo has posted, we are about to try some personal handicap races at MWSC.
we are not using the warwick system because we could have a problem with some people trying to cheat it.

like one person tried to do when we sailed at warwick!

p.s. how is your dad  these days? is he still playing with tractors?

Sadly folks, the numbers don't lie.  The handicaps are right......based on the returns gathered........they just don't feel right.

"Banditry" really comes from the ability of top sailors to sail away from their "median" fleet performance.  So it isn't surprising that a boat with a recent influx of good sailors, a great circuit, and recent design development recently can "outperform" like that.

Especially an over powered design on flat water - where many of the RYA returns may have come from sea-based venues....which does usually slow down the middle section of the fleet relatively more.

Of course, it is just the good sailors that garner the complaints....noone gets outraged at the bloke who finished 235th at the BM...just the sailor who won!

Does anyone know if the BM, GGP Battle of the Classes etc are used by the RYA as validation points?

BTW - well done the Phantom class.  hopefully we'll get somewhere closer to you at the battle of the classes this yr.

The Moo, Late starter and Doug H, if your clubs are using sailwave (which is dead easy to use, and is free) you can apply to the RYA for a password for the PY returns website. Once you have input your race data, you can then ask sailwave to upload the results to the RYA website. The site then calculates all the information as you see on the returns sheet for you automatically. You need to do no further paperwork and wouldnt need to sbmit the paper return to the RYA. It really is a simple site to use, although as per most computer programs you need to learn its "quirks" at first.

I really would recommend scoring using sailwave (makes publishing to your website a doddl too) and uploading to the PY returns website on a race by race basis which really does take minutes and after a while soon builds up into a very useable spreadsheet showing what the "suggested" handicaps might be for all the classes racing at your club. Useful if you do ever decide to tinker with the published numbers to tailor them to your local conditions (as the RYA recommend clubs do but as has been mentioned rarely happens due to political reasons).

Again the offer still stands if anyone at MWSC needs help/advice should you contemplate using sailwave I'd be happy to assist.

Thanks Chrisg, thats a really useful explanation, much appreciated. I guess I need to ensure that the club starts using Sailwave.

I believe not,and from a statistical point of view single races have very little to offer. They should, of course, be included in the organising club's handicap returns.

To be fair it can't be said that 980 is realistic in any but the most favourable conditions. This is more of a fleet wide inflicted personal handicap as there is no way a Phantom is as fast as a Fireball.

It could be argued that they are as fast as a Merlin on the right course, this is borne out by the results of the Barrel series in the Midlands (Phantoms go off 1030, Merlins 1005).

What you guys are missing is that if there are some clubs putting the PY down 60 points then there must be other clubs putting it up 60 points... (well its more complicated than that, but that's the meat of it).

I used to be critical of the PY system until I went to an RYA presentation on how its run, and came to the conclusion that even with my monstrous ego I couldn't think of a way it could be done any better...

Jim.

I don't argue with your (or the RYA's) analysis of the statistics, or that the PY system is the best we've got. But surely when so many people from so many different places all cry 'wolf' that would lead any sensible person to at least accept the possibility that there is in fact a wolf out there.

 RE The Phantom, Its certainly beatable at our club - but we sail on a large reservoir with good breezes and long beats / broad(ish) offwind legs, so it suits asymmetrics or other kited boats quite well. The Phantoms can and do win regularly - but not exclusively, so I'd guess our return for them would be around the same as the PY.

On the other hand, we have some excellent Laser sailors, (National open winners) and they never win (unless its flat calm or nothing else survives). It strikes me that the Laser has an appalling PY - as do a couple of other big classes and maybe thats as much of a problem as the perception that some classes are bandits.

Can someone please post a link to Dan Holmans excellent chart showing his calculated Yardsticks.

I'd like to see where the Laser / Phantom / Streaker / etc lie in his theoretical model.
