For the original owner, do you have the results of races where he sailed other boats, so it would be possible to see whether he was over or under performing in the Icon?

Hi Marke

Understand your point of view and we can bat this one back and forth for a while I guess   ... but there is one irony to your highlighting Paul Barletts Icon at Starcross I don’t think you are aware of ...  Icon '18' was bought as a used boat and Paul was not the first owner. 

'18' originally sailed at another club in the South-West.  The original owner wanted Icon in order to compete in his clubs handicap fleet alongside a number of Tasars amongst others, especially relevant here given the threads title.    Apparently they struggled in ‘18’ to beat the Tasars on the then used handicap that must have been around 1000.   I'm sure this can be checked.   Naturally he was disappointed and asked for set-up tips etc.

Worse still - he struggled to beat the Tasars over the water.  In the end he put ‘18’ up for sale and fortunately Paul saw potential and a bit of fun in the making !

Now should I or we crunch a few numbers to prove that Icon should have a handicap closer to the Tasar's 1018 based on this first owners results ?   Would this be useful or convincing ?

Perhaps we could take both sets of Icon '18' results, doubling your sample size, and average them ?  Still No ?  Well of course I'm not convinced either.

But it is exactly the same boat we are considering - but now in 2 locations and with 2 different.   crews.    The real question is ... at what sample size (both crews and boats) can we have any confidence in producing a usable useful average number.

We will argue the current  EN is based on far far  too few samples ... you might counter that anecdotally you know of an obviously fast one as you have ... (but as we know sailed by an exceptionally capable crew who would be top end in most dinghy classes they chose to sail in  - and has done so in the past  and even  in cats ! ). 

But is a better interim method possible that avoids all these 'discussions' ? - We don't want the hassle either !  The proposal on another thread was for initial assessment on the water by as independent a person or persons as possible - and for the new class to agree to be excluded from any 'official chocolates' during this period at major events if that is what it takes.   After the number ‘feels’ useful then revert to the ‘standard’ system ... and no more moaning either way.  

I'd sign up to any reasonable initiative along these sort of lines and I suspect many other boat suppliers would as well.  Perhaps I should address that proposal to other builders of new classes if no official body responds.  As you might suspect they usually have a few  ‘watchers’ on here !

Anyway this feels too much like 'work' ...so I'm off sailing now ;-)  Yes that Wednesday evening pursuit at Burghfield.

Mike L.

Doesn't Parkers have a foot in both the UK and US, other than that, I guess Rondar or the Boat are at Beer would be the other options to throw out there in speculation....  

Anyway, 3 builders in 3 years.....  Confused

I guess as it's no longer on their website, nor is the sub-domain live, we can assume they are not planning to do that anytime soon?


That is a shame ... the Devoti connection looked like the key part that could have actually got the class established outside of the UK ... without Devoti's involvement seems the class will be come a UK niche at best ...

I hope the new builder is Ovi or Winders otherwise people will always covert the Devoti built ones ...

I think we have been through this before but if you want to use a formula like Peaky proposed then you need to start from a known performance baseline.  If you want to change the performance baseline and work out the relative performances of each class from first principles then you are going to need a VPP that can be demonstrated to work for everything from a I14 to a Topper (I'll exclude foilers so that it is just probably impossible rather than absolutely impossible).  I'm pretty sure that you got no takers for doing that before because it is so difficult to do.

My offer of two years ago stands - if you come up with a formula that you can demonstrate works for I14 to Topper,  I will code it up and put it on a website for you.

There is no published number, and in my opinion, given that the Topper is set these days at well over 1300 (from 1290 a few years ago), it would seem to me that 1220 really isn't that kind a handicap for a small, fairly heavy rotomoulded dinghy. In fact, given that the Tera Pro is sailing off 1350, and the Feva XL off 1222, it could be thought to be harsh. Whitefriars SC are using 1260 as a trial number.

I didn't think there was a current published number for the quba.

Another thing personal handicaps can be good for is marking progress. We have a couple of series which are dual scored, and its a nice progress marker for new sailors as they go from personal handicap band 5 through to 4, 3 etc (the way our system works they are in bands equivalent to 5% increments of corrected time).

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.  

I mean 'unfortunate that she may win' because her personal handicap combined with the boats generous handicap will skew the results. My personal handicap is also generous but the Lightning PY is about right, ergo, she will beat me.

I don't like personal handicaps, I know I am crap, I don't need someone putting it in writing.

I'm a little uncomfortable with peaky's formula given it was derived from the position we have now, which imv is wrong.

If we were to 'start over' with a formula, I'd like to see it grounded with say the Laser as a null point at 1000, or if that isn't acceptable, then the system reworked with it at 1100 and everything else works around it.

There would at least then be some basic in Logic that could be applied. The Laser after all doesn't change and shouldn't. (Having said that two minutes later someone will acquire the rights, fit the Laser with a Carbon Mast and change everything.

But if at the very least a website with input capability and an instant output could be built which isn't beyond the wit of man, it could be designed to vary say the crew weight and individuals could be ascribed to their own handicap.

By the way i ran the Icon through my version of that formula and it spat out 997 based on a crew weight of 160kgs, 985 at 150kgs & 973 based on 140kgs crew weight.
