Hi Jake

Difficult problems to solve .

Mike mentioned race committee discresion ,now on modifications to boats to assign a number ,--hugh discression . R C discression as to windspeed and how this affects P ratings numbers ,--human bias and favoritism enter.
no consistant way for Prating to adjust for spin sizes ,-even with the same class. -No consistant method for assigning new boats a number , we saw this year . No readily available information to all catsailors on how P-rating numbers are derived , --put the race results and times of recorded race results on a web site . Encourage discussion on ratings based on accurate inteligent complete information .
Older boat P-rating problem --assuming info that is innaccurate and incomplete in numerous classes of seldom races boat types .Boat types now need to be broken up into CATAGORY PER DISCRESION .
The base philosophy which is impossible to verify or ever obtain enough accurate information as is evident by results .
Very different levels of ability of skippers being recorded and P-ratings based on these skippers ability in class .

Applying Prating to distance races it is never intended for ,-spin -no spin ,-and numerous other problems combined .

Trying to think of a sport which uses a brand or vehicle type to handicap all in the sport . really can not think of any similar examples that attempt this the same way -

Golf ?? P-Rating would be like giving everY one that played with Nike clubs a par handicap --factor Tiger Woods in the mix ,--everyone that played Mcgregor clubs a 10 or so based on averages ,--Titelist a little lower ,--maybe knockoff type brand clubs a 20 or so on average . -----It really makes about the same amount of sence as rating catamarans this way .

We have people like Matt and several others that are at the level of a Tiger Woods comparitively , and we base the handicap of that class of boat to a large extent on their finish times . --again -does this make sence to any ,-
There is the false assumption in P-RATING THAT THIS SOMEHOW ALL EVANS OUT ,--there is no evidence of this ,-and the reality of people who are experienced racers tell them the opposite .

No rating system is ideal ,--but this should not be applied to any racing where good class racing is available ,-or to distance racing .

Again this opinion is based on the true intent and ideas of sport ,and also understanding that catamaran developement and racing is about improving design ,-not favoring slower sailed boats with an artificial handicap .
What is the true intent of racing catamarans

Happy Holidays

--mARK WROTE -That's the spirit... Distribute those drinks from the cooler and persuade everyone that they have the wrong boat... and gee your type of boat would be perfect for them!

c-THATS THE SPIRIT -perswade others not to build a class in their area ,-be it A Class -Hobies -or the dreaded Formula Classes opposed for years , which you attempted to discourage and continue to with mis information .
-That's the spirit...... and gee your type of flawed P-Handicapping would be perfect for them!

--Mark ..>Failing that and when everyone sober's up... Realize that the overwhelming number of racing sailors are racing handicap in the USA (PHRF or Portsmouth).

WRONG -not in catamarans -the vast percentage historically and now are in Hobie Class racing . P-rating historically alienates Hobie and other class oriented catamaran racing sailors . They realize their large active classes with excellent sailors in each that get the max. from each type in class are unduly penalized in Prated handicapping.--When good class racing is there ,-and that is why you purchased the boat ,-then why bother with an artificial handicap .--Hobie sailors insure numbers in CLASS before attending an event --{roll call } -or they do not attend .
Just like some who say they will not attend Spring Fever or other regattas unless run their way ,-based on artificial handicap.---mARK ?.



Mark >---Remember that even in the worrell 1000 with the same 1 design boats.... competitors are finishing 4 hours after the leader... Holes are a fact of life
WRONG -If the wind is consistant the fleet often will finish within 20 to 30 minutes of each other ,--excluding those with mechanical -gear related delay .
C-Yes Mark --in distance racing often boats seperate some go offshore and end up in very different weather patterns --

Just more reason to never apply P-rating to distance racing .
P-rating is irrelivant for distance racing for these and several other reasons .


M-2) Nobody is pretending that you could race Hobie 16's with spinnaker boats and get accurate results.. Most races group the big boats with spins in a separate division from the little ones so that you don't get skunked by a Hobie 16 while on your Marstrom 20 or vice versa.

EXACTLY -why race a M-20 and H-16 ,-
Boats must be raced in similar groups ,-
The ideal being one design or Formula groups .

I-M> personally follow the this piece of advice from Jim Teeters

C> If you want to race the floating bathtubs dingy types with very similar hull speeds --5 or 6 --whooopee --under P-rating that he refers to then fine ,--go race it -


"Finding the right rule for you and your boat - Lightening -Interlake - etc-is much like a marriage. There is no such thing as perfection. you need to review the pros and cons with a cool rationale intellect, yet go with your gut instinct and what looks attractive. There can be a wonderful honeymoon of great racing (winning more than your share) or and abrupt disenchantment (loosing more than...)

Racing catamarans --it is fun fast exciting challenging ,-all the wonderfull elements of true sport .
We traditionally have great dinners and parties after ,-always more than half the attraction to the sport ,-the great folks and wondefull shared human experiences of it and its special challenges .

Apply P-rating to a small local club ,-if that is the preference of members ,-It is clearly not for H-Class and numerous other catamaran class oriented events .

If we must have a rating system then lets adopt one that is constructive and benificial in nature that measures and helps us improve and understand boat design ,--for safety and many other important reasons .

-HAPPY HOLIDAYS

I am pretty darn happy with my rating, but others arent. I like to be fair so it bothers me.

Hi David

Your square top G cats are not recognized as a class... the results from your races are collected under the modification to main sail bin and not to the stock G Cat class.
Are you sure that your RC is modifying your PN numbers with the correction factor?

The goal of any handicap system is fairness in the ratings; I don't think that there is much fun in racing a boat that is way off base.

I would email Darline and the Portsmouth committe directly and determine how many Gcats are racing and in what configuration.

Merry Christmas
Mark
