And how would you deal with the wind strength factor I illustrated above of the L2 vs Wayfarer? That requires a 10%+ correction. For a foiling Moth it would be 50%+

I suspect I'd be very unlikely to beat you with a accurate PY. And WB: I thought you wanted to get away from partisan decisions made by cliques of so called experts in smoke filled rooms. I personally prefer a data driven system.....but......what to do with dying fleet data. Is it really valid if a handicap on boat performance is the objective?

Transient, there are several factors that could affect a number. It could be that laser 2 sailors are getting slower compared to everyone else due to either boat age diminishing the performance, or thee sailor age and their diminishing performance. It could also be boats have been moved on and the laser 2 is now in the hands of a majority of more novice sailors. It's probably a combination of all of those but deciding how much each one affects the number is difficult.
Are there less returns for the laser 2 now than in than in the past? When does the drop of in returns start? If there is a drop in returns numbers does this correlate to a drop in class event turnout? Something perhaps pyg could look into and maybe already do is to see if and when returns numbers drop if there a certain ratio between that and the Nationals turnout for all classes when a py number moves? If so they could cap it retaining the class best average handicap and not its just current performance. That leads on to other issues too though.

Add to that the classes where the handicap has moved, but the class is still going strong (Topper, Miracle, Comet come to mind) and you get a very complex situation indeed. How would you tie the L2 handicap movement to those classes?

We have the internet, we know pretty damn quick these days, the 'bush telegraph' works, and if we ran it ourselves rather than waiting for an anonymous body driven by an organisation of jobsworths who are purely doing it as a career choice rather than love of the sport, I'm sure corrections could be made a lot quicker than the way things happen now, coupled to an online protest system if folk aren't happy, like this case, and the Miracle and the Icon and the Wayfarer and the Alto and the Streaker and the Solo and the OK to name just a few, they could appeal.

Yes indeed, I heard a similar argument recently....but why is that relevant? I'm not interested in a "Boat age" based handicap, neither am I interested in a "boat crew demography" or a "boat maintenance"/ "availability of spares" based handicap. All I'm interested in is a potential "boat performance" handicap.
Nailing the PY to a figure achieved at the boats peak sounds like a promising start. Surely, The PY should be based on the period of "best quality data" not on a subsequent period of "falling quality data". If there have been no changes to the boat in 30 years then why alter the number?. (sorry to go on about this) If Physicists operated in this way where would science be? If they study the quality of a phenomena would they alter their view and say "but there are fewer scientists studying it now and they are poorer in quality so we've had to change the description in the text books"......not sensible. EDIT: Mr WB, I still support a data driven system. Edited by transient - 13 Apr 15 at 11:10am |

As for spotting which boats fall into this category, as Mr WB says, it's not difficult.
If the returns on an established boat (in the case of the L2, international status or possibly choose some other criteria) start suggesting a slower PY: Flag it for further scrutiny. Ask a question. Has the class changed it's rules? If NO then leave. If the PYG have insufficient funds to apply this kind of scrutiny then the RYA need to spend a bit more on the system. Handicap racing is becoming increasingly important to the sport. |

But how do you know the data was right to start with? If a class has been sailed to above average standard in the past copared to other classes, then by leaving it at the level it was then, you are doing a huge disservice to those currently sailing the boat, racing against classes that have never had those heady heights of participation.
As for using the "everyone knows" technique of number adjustment, as WB suggests... well, I think you've proved over the years that "everybody" doesn't know. They have opinions, based on very narrow experience. I never did get an answer to the question of whether Solos and Streakers raced against each other anywhere, with equally skilled sailors, and how the results turned out? And it sounds like the Solutions have been beating the Miracles at Redoubt, if that is the right club, so maybe 1210 not too much of a bandit number after all? |

Ultimately no one can know if the data is right in the first place. All that can be done is to ask "when did we get the best data for any given boat" .........as you said in a previous post:
....so the period of decline is going to reveal poorer quality data as to the true potential boat speed.
Please don't take offence folks but the sailing community, of which I am one, are notoriously partisan when it comes to judging other boats. Expecting an unbiased, objective opinion from a bunch of experts is a bit like expecting s**t from a rocking horse.....so I would agree with you on that score.

The Solution now has I would guess a slightly favorable handicap, or it could also be that the two helms using them would have been sailing Miracles in the past so they can't both be on the water together. I haven't been down there for a bit, but the Solo Streaker question is pretty obvious, One has an 8.5 mtr sail the other has a 6.5 mtr sail and given size wise there aint much in it, it's fair to say even an imbecile can spot which one is likely going to go faster, either way they are not nor ever were the same.
