 Topic: Yardstick - Inaccuracies?Posted: 14 Aug 06 at 1:08pm |

So, is there a list anywhere, where you collectively discuss obvious
inaccuracy. How often does this yardstick thing get sorted. Who decides it, and how do they come to that decision? There's a clear cock up with this Laser 3000 v the RS200 for example had it graphically demonstrated on thursday even allowing for competance v incompetance, the one boat sits so much higher in the water (More volume on the 200)so annihilates the 3000 once the winds gone, yet it has a higher/slower rating, how did that happen? Are there variations say for a boat like the 3000 that can be crewed or single handed. Do clubs mess around and use their own versions. Are they (obviously) biassed toward windy conditions? If so, then its a bit of an anathema, since its only light weather when the hull performance rather than sailor skill counts surely? Or am I missing something and just dont get it?

Portsmouth yardsticks are based on the performance of the boat and crew in races. Each year (some) clubs make "returns" to the RYA showing how each boat did. The RYA then plugs this into a "Black box" of some description and new/revised handicaps result.
As you can work out. The boat and the crew are handicapped as the new numbers are based on results, so if you have a boat that is not sailed much and is sailed very badly, then the handicap will slowly drop (get slower) and so will become un-realistic if "fast" people start racing the boat. PY also does not deal well with development classes as it is always lagging behind the developments. |

Yes. It's only handicap racing. Go class racing if you want the real thing. You could try finding out if your club makes its annual PY returns to the RYA, which relatively few can be bothered to do. And if your club doesn't do it, you could volunteer to take on the job.

Yes we've been on to them for years about settling on a class to race, but just as soon as it looks like its going to happen one of them ups and gets something else, we've got lsr3000's x3 and a few Supernovas, but its a small coastal club, not many of us, we get about a dozen boats out on a thursday night and maybe twice that at the weekend. It used to be a scorpion club in the day, but now there are so many different boat types, and as you may have noticed on the what boat thread, nothing ideally suitable to our water. So, the handicap is a way of life. I'd be interested in finding out more, how to calculate it, how to submit what? Results, times? Its not obvious on the Ar why eh? site. Just thought some of you lot might know. Not much used to me alive are you Turkish... Edited by Graemef |

Because as soon as the wind is up, the 3k will annihilate the 200, and on average the wind is up sufficiently for that to happen. PY's are necessarily averaged over all conditions experienced, which means that on any given occasion for any given boat they're likely to be too high or too low. You can hazard a guess at sets of suitable PY's for, say, dispacement, marginal planing or planing conditions, but it'll be a brave race officer who'll take the decisioon which set to use (then the wind will change), and is that marginal planing for the MPS or the Wayfarer? It's a minefield. You just have to turn out and believe that on average you'll have a fair chance. But beware only turning out when it suits your boat or the PY might get worse - you need the 'race returns' to the RYA for the bad days in order to improve (raise in this case) your handicap. |

Something i think that is long forgotten about py returns is that you ARE allowed to make your own modifications to the py's through the year and send them off to the rya. Everyone seems to see the rya's number as the be all and end all even if they dont like it. However no one makes the collective effort to make adjustments and py's will only get better if people experiment with them. |

Handicaps are far from perfect as they are averages over quality of sailor and condition - the problem is that unless you are class racing there is nothing better!!
