I think you may have wrongly accused Mike of the anger and personal attacks, they are coming from me. I can do this, I have no commercial involvement, I believe the system that awards these 'handicaps' is wrong, morally, & ethically, it also loans itself to such accusations due to lack of transparency and the behind closed doors in smoked filled rooms nature of its application. There is an easy solution to it, I don't know how many times it has to be presented to 'them' but if it were, and the formula open to scrutiny then there could be no adverse comments, the rest of the system could continue, local clubs could vary it if they have the political clout to do so and there would be no 'personal' attacks. Now we need people like Mike, Rodney, RS, to continue to innovate rather than warm over old dross in the hope of sales through temporary handicap advantage, at the moment the system encourages just that, products for the dubious of character, whilst those of us happy to purchase a brand new untried and tested boat are then punished for doing so by a petty small minded and protectionist elite. That's why they are being attacked for being that way. Edited by iGRF - 30 Jul 14 at 8:55am |

It is a catch 22 situation though. The system cannot give an EN without data and you cannot get data without a PY number of some sort. There are guidelines on the RYA website for the issuing of a PY where one does not exist so there is very much and element of finger in the air here. The manufacturers/developers of a class are damned if they do and damned if they don't (but they will have an idea of where the boat will sit in the established tier of classes). Take the D-Zero The distributor has been unwilling to be drawn in to a PY discussion. The general feeling is that 1040-1050 is the likely range. Most clubs I know of are using 1044 or 1045 as a start point. Others are using the great lakes data (which is based in Dan in his Punk IIRC) which give 1010. One club are being stupid and using anything that says Devoti from the PY list so one guy was allocated 959 (the D-1 PY), I think he has made presentations though.

It is possible to make an educated guess though (for those with education). I have never seen a D Zero in the flesh but looking at pictures and specification it should be just a bit faster than a Supernova. Similarly Icon should be faster than Tasar (if it wasn't there would be little point in making it) looks like sub 1000 to me, say 900?
My gripe with the Quba is that no common sense was applied, perhaps it was not taken seriously, It is quite wide, not that heavy, fully battened and has a point at one end so how could it be only 1220? It is a proper boat not like blunt and flappy Topper.

And Rodney is absolutely right not to get drawn into the debate - it never looks good.
FWIW - most of the discussions I've seen with D-Zero sailors re PY doesn't have any sour edge to it. Even the GL number seems to be 'accepted' as nothing more than a first step- the last thing the D-Zero needs is a bandit handicap reputation from 'cleaning up' at one of those more prolific events. It'll serve the core customers (club sailors) poorly if that were to happen, so best the GL team err on the side of caution until a proper EN is published, which at 1010 they would seemingly be doing. Even then, it's not that harsh in the grand scheme of things, although I agree using the D-One handicap because it has the word 'Devoti' in it sounds a bit riduclous ![]() With guys like you sailing them regularly, it won't be long before the RYA publish something- then when something has been published, that will then give a basis for comment and discussion from those with commercial agendas.

This is exactly what the RYA advise you to do: and What they are saying is that if there is no number then the club in question should use a Trial Number, how they arrive at this is the educated guesswork. Once data starts to go in then and EN is likely to be issued. It also says that a TN or EN may not be right for every club and they should be reviewed. The framework is there it just needs to be used. The problem comes when those who do not contribute to the system say it does not work (but we have been there already)..... I suppose one way round this would be to make submitting a return a condition of the clubs RYA affiliation (with the RYA offering assistance where clubs are struggling).

Marke, who has already fessed up he works in stats, wrote this yesterday:
I'm assuming Dan's technical analysis is the type of formula you want adopted ? Marke's comment above states the EN is about right when it's calculated. Would you now accept the Icon's EN is the correct starting point ? |

Sorry for going O/T, but I predict one of the beautiful things that D-Zero owners will come to appreciate is the accessibility of the boat across the wind range. It will do very well in light winds, (all of us who've sailed like its 'get up and go', even the portly among us seem to be defying Dan's initial view on weight range). It will perform on the sea judging from feedback from the Punk and it's (from what I can tell) vice free, that sailing in heavy airs will be something to enjoy rather than something to endure.
Putting it bluntly- in light winds I reckon me ghost-racing myself could quite happily live with a contender across the water in sub or marginal trapping. In heavy winds, the easy handling would mean I could actually get around the course- something I couldn't do in my RS300 once it was stinking windy. And whilst I could get a Phantom around a course in heavy airs, it would be subject to grimacing rather grinning, so again the Zero would be winning on the fun factor. Those are all sub-1000 PY boats, (a new Phantom is sub-1000, averaged up by old woodies!) so if the handicap ends up anywhere between the 1010 of the GL and 1044 of a Rooster 8.1, then I think it would be usable across the wind range and sailor weight range. It's such a nice, simple boat... very much what I would hope the Icon to be if/when I get to try one one day.

The trouble is that when arriving at local boat handicaps it becomes very personal. The most boats we ever have racing is about 22 but regular active sailors is about 14 - 16. If we help out our Phantom sailors by adding ten points it would offend our Supernova sailors. If we penalised Byte because two of them win all the time it would upset the two who do not. The lady with the Quba is rather given to emotion and if it was suggested that it was the boat PY that was assisting her rather than her own skill she may have to be restrained!
I do worry however that said mad Quba woman may enter one of our personal handicap pursuit races, her personal handicap/boat handicap could produce an unfortunate result. If this did happen I might have to miss the Trophy Presentation Evening as my Salmon en croute may stick in my throat!
We are a close and happy club and wish it to stay that way. |

I think it was a Peaky's analysis that gave the number in the same ball park. However you would hope that the two analyses wouldn't be very different. [Somewhere I coded up Dan's analysis so I could do some comparison with the local numbers my analysis generated - I'll see if I can find it again - but its probably two broken lap tops ago!]
One caveat - with this type of regression analysis you need to be careful with points at either end, and with the Icon being at the far left (fastest) for this category of boat you would need to look at the data quite carefully. |

I assume you mean unfortunate in that she may win ? What's wrong with that ? It's a personal h/c and it means she - to use Marke's term -"over achieved". Next time, she'll not be given such generous personal h/c. I believe personal h/c club racing is very encouraging for novices. The best format is pursuit racing. If needed, one's personal h/c can be changed weekly. Hot shots and novices all in with a chance of the chocolates. Very inclusive and just what GRF advocates. |
