There is a fellow from spain that posts on here occasionally. IIRC he is just above 1, like 1.005 to 1.01 or somewhere there about from memory. You might try searching on here, as I know there is a post or two with the info, probably 2-3 yrs back.
I want to say the member name is "Safarion" or something close. He is also listed in the owners directory IIRC too. The three local SF 37's I know of, all have PHRF certs, and no one to my knowledge has an IRC cert.

Thanks Marty I'll have a search as you suggested.
I found the ratings around the same as you suggested in other lists (Cowes Week entries etc), but not sure of the sail plan they were using.
cheers

mark,
I have some polars from safarian sent me, that he made up, all of it is in french, but even a french flunkie from HS like me can figure out the sails he is using. I could email them to you if you do not find him in the mean time. I ws toying with buying one a few yrs back, just could not get the dollars to line up etc. with the recent recession/depression here in the states, I am glad I did not.

Cheers Marty late reply I know, but I got a couple of old certificates from one of our rigging suppliers. Our boat has a 130% furling headsail and no Heavy Weather Jib, assymetric and vmg spinni's and an overlength spinni pole. We ended up with a rating of 0.980, about the same as a J92 slightly less than an X99 and 53 points less than an X35! The only comparable boat in the IRC database has a rating of 0.989 with standard rig. We will probably go down the route of creating our own Polars, which will be useful with our non-standard rig to understand which are the best angles/sail combinations
cheers

Hi Mark Our 36i standard (not performance) rated .997 on IRC last year so it sounds like a reasonable rating. From various things i have read most people say the sunfast37 is faster than a 36i. Do you ever get to race any 36i where you are? We could never sail to our rating so have not continued with IRC.

Hi Barry We are the only Jeanneau sailing at Ramsgate...at the moment. The old certificate I obtained of other UK boats were from 2006 and the rating was 1.003, the same boat rates at 0.989 this year. Age allowance, improvements/changes in the rules and regatta result feedback have no doubt resulted in this reduction. We have gone for slightly smaller furling jib and a medium size spinni, so that probably accounts for most of the difference in our ratings. You should consider coming to Ramsgate Week in July and participate in one of the 'Gentlemen's' classes. The ratings are decided by the sailing committee and if you don't win you can console yourself in the yacht clubs new bar (www.rtyc.com) cheers

Hi Mark
A bit far from Brisbane Australia to where you sail. What is the SSS number on your certificate.
Barry

Mark and Barry,
We don't do IRC but are keen twilight racers and Winter Wednesday sailors on Sydney Harbour. In our Greenwich Flying Squadron fleet we have four Jeanneus, a Sunshine, a 39ip, a 36ip and us. Ours was a SO37 which we have rerigged with a taller mast, longer boom and 300kg of internal ballast. We perform very closely to a SF37 in the Winter Wednesday races so I think we would class ourselves as a SF37 for all practical purposes. Currently our handicap is higher than the three previously listed Jeanneaus although it has taken a while to get to this stage. With equal crewing and attention to the hull condition I think the SO39ip would be a couple of percent faster than us and the 36ip a couple of percent slower. The Sunshine is a great performer particularly in the light conditions with a clean bottom. Our mast height and fore triangle is similar to the 36ip but our boom is a metre longer. We also carry a 160% overlapping genoa which helps us against the 39ip non overlapping genoa downwind. We have found that the Jeanneau 37 hull needs a lot of sail area to get the most out of the hull and that needs to be compensated by additional ballast. I would love to see how the 37 hull would perform with a 2.4m draft and 1700kg ballast. That would get 400kg out of our boat without changing the righting moment. While I am dreaming I would also like to see how the 39ip would go with the rigging up against the cabin and with a big overlapping headsail. The new 409 look fine in this regard but the mast is a metre short for my liking and where do you put the extra winches for the racing days? Regards David

Moleman, your post referred to "standard rig" ; what size Genoa is classed as standard rig? I'm planning on some new sails to race, most likely under IRC, although PY may be an option. What sailplan would folk recommend?

To answer, very belatedly, the original question, I've come up with a 2012 IRC cert for a Sf37; it gives a rating of 0.979 (0.967 with no spinnaker) based on a single furling headsail/HW JIB and folding prop. You asked specifically about overhangs: bow 0.62, stern 0.85
is anyone able to answer the the same question with respect to PY rating for a SF37?

...in terms of likely handicap, as I'm going throught the same process for my SF37, I've noted these ratings from recent offshore races; Chatterbox 0.957, Dignity 0.997, Nomad 0.986, Stormtrooper 0.996, One Life 0.977. All these refer to races this year.
