FWIW, in 1961, the Firefly had a PY of 103 with cotton sails or 100 with Terylene sails.
103/98 for an Enterprise.

By the mid 70s, PY had been changed so an Enterprise was 118.

In the early 60s, there were a small number of  'primary yardsticks' which clubs were not encouraged to change, and lots of secondary yardsticks. Most of the primary yardsticks were very close to 100.

This approach might have avoided the @@@ Island Effect, where a club lowers all its fast fleet numbers and raises all its slow fleet numbers so Mirrors can race against Fireballs once a year, then returns a lot of Fast Fleet races where the numbers are all in Fahrenheit to everyone else's Celsius so to speak.

The original Portsmouth Yardstick system did have a scratch boat set at 100, it was developed in 1947 by Stanley Milledge, who was in charge of handicapping racing at the Langstone Sailing Club and he designated the Island One Design as the scratch boat. I don't know if the Firefly's 100 PN was coincidence or planned.

Yes, sorry for taking it off at a tangent but It's traditional ;-)

As far as I can work out the RYA spends buttons or nothing on the system. It's administered by volunteers. I guess the electronic returns part cost something to set up.

I reckon the volunteers do brilliant and diligent work given the job description. 


I hope your observations are the result of more returns from coastal clubs, it would certainly explain perfectly the changing numbers.

As to the OP, 1, the Laser was hell on its pre-digital yardstick both radial and standard and 2, the Laser is boat of choice for many beginner racers on a budget, so the curve is weighted away from the usual mid fleet, mid level boat average.

No idea why fast boat yardstick are going down - maybe with reduced fleet numbers, more of the fast end are handicap racing?

You answered the second part of your question on page one when you said

 I think the main reason is that PY is a relative rather than absolute scheme, and therefore 1100 in one year does not need to bear any relation to 1100 in another year. 

IIRC, when I started racing in 1965 the Firefly was the scratch boat, rated at 100. But I don't know if the PY committee maintained it as a basemark or allowed it to drift as is the case today (a look at the PN lists from the start until, say, 1970 would give the answer). Either method gives rise to anomalies as even the strictest one designs, (like the Firefly and Enterprise back in the '60s and the L@ser and many other SMODs more recently) develop and. presumably, get quicker in real terms.

Does it really matter? All my club racing is PY (inland pond) and involves a whole variety of boats with a wide variation in helm ability. Anything from RS400 to Bosun - often sailed singlehanded - and the usual Laser, Aero and Solo. I have become quite competitive in my 40 year old tin rig Europe, even winning a few races. Other than being very enjoyable and providing racing experience I don't take it too seriously. I can easily beat the Aero sailors on the water yet often can't get past a well sailed Comet. 

The only reliable measure of my actual ability is when I go to Europe class events, I'm slow - but that's ok as it gives me something to work on. Europe.... fabulous boat by the way.

In reality this will never work for various reasons:Lack of expertise within the club.Over burdening the club with another volunteer job that needs doing. It then gets done for a season, the volunteer gets some grief and then gets fed up with it
[/QUOTE]

SL, I totally get where you are coming from on the extra burden/lack of expertise along with internal criticism/debates etc which are part of every club's life. Here on the tidal Thames we have been pulling the PY system apart in a sense with a much faster boat in the X1 than the presently sailed Lasers and Ents and we've certainly experienced this with ups and downs - e.g. at one stage our Club Dinghy Committee assigned us 850, not quite sure where from (...yes, for a 16ft non-trapeze monohull with sym spinnaker). But things are now a bit more sensible around 900 - being the tidal adjustment from the still water 942 that we arrived at following testing at QMSC (with Andrew from there's help on data crunching i.e. pretty much the same as an RS400). The HISC adjustment system for us would in fact be to 919 but I think this is probably not enough.... Unless of course we are doing the downriver races when even 942 you could claim would penalise us.

But then on our normal 2hrs before HW up and down racing when it's very light winds and a spring tide, when we are going forwards against a tide and the Lasers/Ents are going backwards we rather easily make our handicap

But having said all this I still think it should be the clubs taking responsibility for any tidal or other adjustments (as HISC and the Great Lakes groups indeed have done) as I can only see even greater problems with a variation formula imposed from above.

One idea to overcome individual club capacity/politics/debates could be, very much like the GL group, to link up with other clubs that you believe have very similar tidal waters and develop your own common adjustments to the PY numbers. Do you think that would be something your sailing committee would be up for?

One thing about the RYA PN is it basically works.. yep not for everyone and also not for everyone all of the time.. It is about averages for a season in all conditions.. I've won a race in my 1151 handicap boat against a 1036 handicap .. Once.. Why? high winds and they had to reef. Normally their larger and taller sail area overcomes anything I can do..

Take the wrong boat to the wrong waters and you have no chance.

From my own point of view, too many boat manufacturers every other week have gone for a new all out planeing machines, that needs a lot of skill to make to perform and needs open water..

As someone American said  "in the UK They'll  find a puddle and  put a sailing club on it".

The Americans had their D-PN system, which they are dropping to be replaced by RYA -PN
In larger boats they use PHRF which has many different versions around the USA, some versions take account of tides / wind strengths, as well as them all using boat statistics.. I see pages of complaints about it....
There is no perfect system.. you can't put monitoring systems on every boat (yet) and on every point of the river / sea / lake,  for wind  /tide / sun / someone sneezing. Without that no system will ever be perfect
Still sailing in circles
