In nova Scotia currently all boats have same rating. Sis. Stuck in snow.  None

Seriously it is often stated that in other than fun races spin and non spin 
should be separate fleets.

Rick said  If I have a fleet of 8 to 10 CC sailboats competing in a single 
event over the same course at the same time, but in different (spin  Jam) 
classes, what is an equitable way to determine which boat is the best 
performer?

Here in Nova Scotia, if we wish to race, we must register with the Nova Scotia 
Yachting Associationit provides a PHRF rating based on a declaration, e.g 
sails, fixed and/or folding propellers, etc.  For example, (from my memory 
which might be fuzzy on this) the NSYA rates our CC 32 at a base PHRF of 165 
with a 150% Genoabut with no spin (+18) and a two blade fixed prop (+6) our 
PHRF to race is 189.  Here is the website if you are interested:

to achieve, there is 'no perfection'.   And think about giving every competitor 
a bottle of an adult beveragethat will distract them from where they placed!

way that you could set up fair starts for a pursuit race using time on time.

Since the discussion is turning to these things, perhaps I should clarify the 
reason for my question, and rephrase it.

Pirates on the Pungo is an annual charity regatta, held in Belhaven, NC in 
mid-May. (This year it will be May 15-17) Most keelboats compete in a longish 
pursuit race on Saturday, with awards given out on Saturday night at the dinner 
dance, and a second (optional) race on Sunday morning. One designs and dinghies 
compete in windward-leeward races on both days. The pursuit course is typically 
the one I described – about 10 NM with N,S, E, and W legs, starting and ending 
inside the breakwater in the harbor. The keelboats compete for three deep 
prizes in three classes: Spinnaker, PHRF Non-Spinnaker, and Cruising. Cruising 
boats are white sails and not generally raced. Usually there are about 30 
keelboats, with Cruising being the largest class.

I plan to conduct a “CC Rendezvous” within the Pirates on the Pungo regatta. I 
know of about 10 CCs within a day’s travel of Belhaven, which allows travel on 
Friday to arrive for the Skipper’s Reception, compete on Saturday, and sail 
home on Sunday. (There are actually 5 CCs at the River Rat Yacht Club just 5 
miles away) And another 10 or so are within 2 day’s travel. Using the event as 
a venue makes everything really simple. Someone else provides the RC, committee 
boats, marks, photographer, the Friday evening cocktail party, Saturday 
breakfast, Saturday steak and seafood buffet, Sunday brunch, the band for the 
dance, and beer and soda for the weekend. There is free dockage available in 
Belhaven. And since the regatta is part of the Belhaven Pirate Fest this year 
there is even street music and shore side activities on Saturday for family and 
kids who don’t want to race.

All I need to do is arrange a race within a race for the CC owners to 
stimulate competition and camaraderie, provide a prize (and I think one of 
Andrew Burton’s half hulls of the winner’s own boat is a really nice prize), 
figure out how to determine the winner, and get the word out to CC owners.

Figuring out how to determine who gets the prize is the reason for asking the 
original question. Participants will be competing for the overall prizes in one 
of three classes, in a pursuit race based on PHRF ratings. I’ve been involved 
in regattas where the overall winner got a prize for being first in the “most 
competitive” class, but never thought the methods for determining “most 
competitive” were very equitable. The other alternative I could think of was to 
determine an adjustment to the PHRF ratings of the JAM boats, and then score 
the CCs based on their actual time on the course just like you would a Time on 
Distance race.

So let me rephrase my question: If I have a fleet of 8 to 10 CC sailboats

 consensus opinion on how to adjust PHRF ratings to allow spin 
 and JAM boats to compete in a single (small) fleet

Typical it works poorly. On moderately heavy days were most boats can
get up towards hull speed and sail deep downwind the JAM boats will be
about as fast as the spin boats but will carry a +12 to +23 advantage.

On very light days if the scoring is time-on-time while everyone is gently
drifting downwind the boats with a +24 will be accumulating too much
adjusted time.

In moderate wind conditions the spin boats will sail to their ratings, but
so will the JAM boats. Might be fair for those days.

The race on Saturday is a longish (10-12NM) pursuit race that starts and 
 finishes in the harbor and has north, south, east, and west legs.

For PHRF Lake Ontario the ratings are based on windward - leeward courses
with 1 mile legs in about 4 - 18 kts of wind. The ratings were never designed
for long distance races.

I raced last summer in a mixed FS - NFS fleet. Well, hard to call it racing and
I am not sure about the summer part either. Fleet spread was 91, and went
from a Kirby 30 and J/80 to a Sprinta Sport. I managed to see first hand all
the ways mixed fleets and wide PHRF spreads do not work.

At least it does reduce the pile ups at the marks you get in a OD fleet.

Very good summary of things I saw too when racing against different style boats 
in the same fleet. 

Instead of the fleet placings, we found we could measure our performance best 
by comparing us against similar CCs. I lost interest in racing when similar 
boats stopped competing and we had to race against a Viper 640, a Pearson 
Triton 28 and a J-24 and a J-28 all in the same fleet. Apples and oranges. I

As I said - pick a percentage and wait for the squawking.

In our Herring Island fleet, we use the Annapolis to St. Michaels race as one 
of our long distance races. Depending on club entrants for that race, we can 
have boats in multiple PHRF classes ranging from PHRF A2 through PHRF C/D. 
Plus, we could have someone running in a one design class (J-30, Triton, etc.) 
- and we have two different course lengths, depending on class - they usually 
have about 15 starts.

We use our 15% NS adjustment - the only problem is we cannot use our 7.5% 
cruising chute adjustment, because the PHRF rules don't allow that, they dump 
them into Spin. We have had high finishing boats come from both Spin and NS 
classes (cruising) and from just about every PHRF group. 

This past year, we didn't have any NS boats and everybody was grouped in PHRF 
classes which ran the long course (21 miles), so it was easy. In the past, it 
hasn't been, but more depends on what the wind is doing and where the currents 
are headed than any other single criteria.

There is no perfect answer, so just choose something.

For me, 15% is better than a fixed number of seconds per mile, because of the 
wide range of PHRF's in our fleet. And, because the course has multiple legs in 
different directions, the good reaching boats may come out better or not 
depending on wind. (A Bermuda 40 yawl with a mizzen staysail is a good reacher, 
as is a J-80 if the wind is right, but if the wind is skewed by 20 degrees, 
neither does that well). 

Good Luck.

Gary in St. Michaels - on the 80 for this one.

This is what we do at our club, Tiburon YC on San Francisco Bay.  We take
the PHRF rating and if the boat is sailing non-spinnaker we add 18 seconds
per mile to the PHRF rating.  We have done this for over 15 years ago and
it seems to work in our mixed fleets.

 For racing on Long Island and the Hudson River the spin and non-spin
 ratings are not intended to be used to combine fleets.

 These ratings reflect differences in a boats ability when racing in either
 a spin or non-spin fleet. For example if you use a spinnaker pole as a
 whisker pole in non-spinnaker you can get a credit. Also a boat designed
 with a standard blade jib is seen to be at a disadvantage when racing with
 out a spinnaker as they have less sail area in the jib to project to
 windward and may get a different non-spinnaker base rating.

Rick,
   I am no expert, but talking with Lake Michigan PHRF folks in past as Regatta 
Chair at our yacht club I am certain others have given good advice: it can't be 
done fairly.  Wind angle, speed course length etc etc all impact.  It is hard 
enough over 12 race season to feel like phrf is fair sometimes. 
  Stick with two fleets.  Fewer hard feelings.

Re: Stus-List PHRF Adjustments for Spin and JAM in a single fleet

2015-03-21 Thread Gary Nylander via CnC-List
Rick, you probably have seen some of my earlier postings from earlier debates. 
We have two small fleets around St. Michaels. Our Herring Island Sailing Fleet 
uses a 15% rating adjustment for non spinnaker boats, with a 7.5% adjustment if 
the boat has a cruising spinnaker (gennaker?) tacked to the bow - no poles 
allowed. It has worked pretty well over a number of years.

Our Wednesday Night Fleet uses a flat 10% adjustment for non spinnaker boats - 
white sails only.

We have been doing this for about 15 years - anything more 'fancy' creates 
confusion. The Charleston fleet has a sliding scale dependent on the style of 
boat, but when trying to explain it to the troops, all I got were rolling 
eyeballs.

In each case, the skipper must make his/her decision before the course is 
posted - no 'cheating' when it is an all reaching course or some other factor. 
In most cases, it is because the wind is too strong, or the crew is too small. 
In strong wind (inexperienced skipper or crew) some racers would not 
participate if they couldn't get some relief for not flying a chute. However, 
when it is blowing and the boat would be near or at hull speed without a chute, 
the adjustment may be too large. 

One caveat - we have series races - Herring Island has three four race series - 
from May to the beginning of October and the Wednesday is one long series of up 
to 22 races all summer - and both have throw-outs.

If you are trying this for a single race, you may want to come up with a 
sliding scale - when it is blowing hard enough to have boats get up toward hull 
speed without a chute, a 15% adjustment would be excessive. I have had races 
where I was near 6 knots in my 30-1 with a poled out genoa and competitors were 
fighting to keep their boats under the chutes and were only going a wee bit 
faster. In medium to light conditions, 15% may not make it even.

Good luck - if you are only dealing with CC boats (traditional ones, not the 
new 30) you can probably choose something which will be equitable, when you get 
into a fleet like ours (CC 115 at PHRF 75 to Triton at 252...), then it is 
tougher.

  OK. I know this has been discussed before. But I just spent almost two hours 
in the mail archives rereading a whole bunch of previous messages, trying to 
come up with a consensus opinion on how to adjust PHRF ratings to allow spin 
and JAM boats to compete in a single (small) fleet.

   

  What I firmly believe I have discovered is that, sort of like economists and 
politicians, if you laid all the opinions end to end they would never reach a 
conclusion.

   

  I know that a number of PHRF organizations give a boat both a Spin and a 
non-spin rating. And I understand that local some local organizations with 
small fleets running in a single event will adjust the ratings of boats in 
non-spin to promote more even competition. From what I can see, the credit for 
running non-spin seems to be in the range of 10-18 seconds, or 10-15% of the 
boat's PHRF.

   

  What I'm trying to do is plan for a CC Cup to be run as part of a local 
charity regatta called Pirates on the Pungo, in Belhaven, NC on the weekend of 
May 15-17. More on that later.

   

  The race on Saturday is a longish (10-12NM) pursuit race that starts and 
finishes in the harbor and has north, south, east, and west legs. I know of 
about 15 CCs within a day's travel of Belhaven, so I'm guessing the fleet 
would include 8-10 boats, with some cruisers and 1 or 2 real racers. To promote 
camaraderie and competition, and also so I don't have to pony up too much for 
the prizes (the winner will get a half hull of his own boat made by Andrew 
Burton), we would have a single fleet.

   

  So help me here:

   

  How does your local PHRF or sailing club adjust the ratings between Spin and 
JAM to allow both types of boats in a single fleet? And how equitable are the 
results based on your experience?

Hi Rick:

 

I claim advantage since I also have a 38MKII, '77 vintage.

 

You could check the NEPHRF.org website to see if your current handicaps are
close for the boats racing.if you have boats that are not registered,
you could assign a rating comparable with the list found there.  

 

However, there are always discrepancies.the known list portends to be
applicable to a boat that is in racing shape  in our case that means that
the sails and equipment are up to snuff and the bottom is cleanI would
expect that some of your participants won't match those criteria

 

What we do in the Hingham fleet is to establish a racing and a cruising
rating for each boat.  Racing rating considers that the regular symmetrical
spinnaker will be used on a pole.  The cruising rating covers boats using
Jib and main only.  For our regular Wednesday night races, we don't have
enough boats to race separate races in each fleet so if I want to race in
the B fleet (which we won overall last year), and we don't want to use a
spinnaker (which I don't have, only an ASYM) we let cruising boats race
with the spinnaker boats and add 10% to the cruising ratingThat worked
very well for us last year.

 

IN our pursuit races, and we have several with over 100 boats entered, we
also (by necessity) have both types of boats racing in the same raceall
in one fleet.  IN that case, boats that are racing Cruising get 10sec.
added to their cruising rating.  Again worked well for us last year. 

 

In your Pursuit race..simply assign a base handicap to each boat and
then adjust it for spinnaker or not racing.  Since the pursuit race starting
time already takes the handicap into accountthen as usual, the first
boat across the finish line wins

 

You could also check out a web site; www.regattaman.com
http://www.regattaman.com/   these guys do the race management for most of
the events in New Englandfind the calendar page and check out the Great
Chase Raceyou'll find NOR's, Sailing instructions, and ratings for over
100 boats from Rhodes 19's to Swan 42's and beyond...

 

If you need more info, check with me off line and I'll send what I can.

 

Best,

 

Ron Casciato

Rick,

This has been discussed recently for shorthanded sailing  on the
Chesapeake.  Bottom line is there is no way to race spin and non-spin
together fairly.  You can come up with a differential, bu it nothing more
than a SWAG

Rick,
In my opinion the adjustment would have to be based on the wind speed and angle 
too much to be do-able. A much easier solution would be to get the class to all 
agree to run in one class or the other...most likely JAM. Any way you do it, if 
I can clear the schedule, I’ll be there!

Re: Stus-List PHRF Adjustments for Spin and JAM in a single fleet

2015-03-20 Thread Eric Baumes via CnC-List
For racing on Long Island and the Hudson River the spin and non-spin
ratings are not intended to be used to combine fleets.

These ratings reflect differences in a boats ability when racing in either
a spin or non-spin fleet. For example if you use a spinnaker pole as a
whisker pole in non-spinnaker you can get a credit. Also a boat designed
with a standard blade jib is seen to be at a disadvantage when racing with
out a spinnaker as they have less sail area in the jib to project to
windward and may get a different non-spinnaker base rating.
