Projection 762 Help please?

   Thanks for those numbers, Peter, they are very interesting. The comparisons for my boat are

LP 3.64
Weight 1300
Spin 44.4
Overhang factor 1.045 

Hull and rig factors are the same as yours.

I have no idea how (or whether) the overhang factor relates to LWP & overhangs, or if this affects the rating much, but my numbers are
LWP 6.93
BO 0.14
SO 0.54

My guess is, though, that the +45kg and -4.4sp m of kite make up 6 points.

If I get a chance I'll get mine weighed I think. I should be able to get hold of a J80 cert, if I do I'll post the numbers for comparison.

	Pink Gin had official IRC weighing (on RORC load cell) in 2005. Weight 1345 Kg. Miss Piggy was weighed at the same time, and was a bit heavier. Reducing jib overlap helped rating,LP reduced from 3.95 to 3.65 probably saved 5 points.This is now approx 140% genoa,the old one was150%. 140% suits the boat well, fine in light airs, and much better near the number 1 to number 3 change. We only sail with 4 people, so this may help with the slight loss of area in very light airs. Spinaker is 40m. Any smaller is a disaster, the boat came with 35m and was sad downwind. I think 40 is still a bit small up to force 4, and plan to try 46m. Other IRC data is:- Hull Factor 10.5 Overhang factor 1.055 Rig factor 1.02 Are these the same for all 762's? How does hull factor compare with J 80, Corby 25 etc.

	Mine is endorsed, too, with a 44.4 sqm spinnaker. However I got mine based on the RORC's "suggested" weight, which is 1300kg empty, but as far as I know the boat has never been weighed.I wonder if that is not a bit light. Has anybody had one weighed? Kev

	Those ratings do look pretty decent. Maybe they carry small kites? I've got an endorsed rating and that was 0.973 for 2006

	Seeing this thread persuaded me to do a bit of hunting around the web for more Projection information, and I found a results list on the Royal Cornwall's site showing 2 762's, Pink Gin and Miss Piggy, rating 0.965 and 0.966 repectively. Is there anybody out there involved with either of these boats who might know how they got these numbers? my 2006 TCF was 0.971 which I had thought was about average. 0.966 would certainly make my life easier! Perhaps they have actually been weighed? Kev Zulu GBR 7622

	Hallo Brys, I'm sorry to hear of your accident. I hope that you're making a good recovery. I'll send you another PM because I can't remember whether or not I included my email address. My only worry about Falmouth as a venue is that it's so far away for us I'm not sure we'd ever get there! However as I've already mentioned it's unlikely that we're going anywhere beyond the Forth this season.

	Brys is my old man, hopefully i'll get my hands on the boat for a couple of events like sail east (west mersea and felixstowe) maybe burnham week/ramsgate week, depending on work and crew. Hopefully we'll get a calender sorted soon Edited by slop_idol

	Falmouth sounds like a chuckle, especially as there are a few proj's there already. Won't be making it this year but could be one to consider for 2008. I'd be very keen to know what the East Coast boats will be up to when they have their calendars done. Will be making a big effort to go to those where other projections will be out.

	Hi Guys, Sorry to be quiet for so long. I am now back in harness after a prolonged recovery from an equestrian accident. Therefore "time is not my own" at present! When I kicked off the idea of a class association it was very much ment to be a virtual entity. We have generated a lot of discussion on this site and word has obviously got around. I still think that to keep work to a minimum and cost at a zero level we could continue to use the very good facility that Y&Y provide to keep in touch. Several people have used the Private message facility to pass their private email addresses to me and I have reciprocated. I am slowly building an offline database of owners and boats and their opinions viz one dsesign and other issues of intrest. If things start to get out of hand and we get asked to move along by Y&Y we can easily move to MySpace site....... If anyone wishes to access the data (still quite small amounts) I have, and they are an owner/crew of a Projection and have sent their details I will be happy to pass on boat info etc...but in the first instance if you wish to contact each other why not use the PM facility here. I am NOT in fvaour of going down a One Design route.......the boat can easily race one on one (as per a BOX rule) If we all keep our IRC certs up to date IF we ever get together in any serious numbers (say more than 3) we can see what IRC does for us and if the small rating differences make any odds.....Until that time which I hope will be soon! I would think that Falmouth would be the best candidate for a meeting of boats and people and would also suggest that to join in a Falmouth week would be the easisest option for all parties.....What do you think? Bear in mind that three boats are already regularly racing in the area. Falmouth is a very nice August holiday destination for families not involved in the sailing and the road links & boat handling is pretty good. (albeit a fairly long haul from anywhere!). Happy new year to all Projectionists and Happy sailing in 2007. Edited by brys
	Never enough time for sailing

	I understand some people's reluctance for one-design in this case; I'm a Laser sailor so initially it made sense - true boat-on-boat racing (well...), stops cash from becoming the vital ingredient, etc etc. However the more I think about it in the case of the 762 there probably aren't enough in existence for one-design to work. The association is vital though. In my experience classes have risen and fallen on the strength and enthusiasm of a class association (as have boat values) and although we're not planning any trips away to race against other 762's this season I look forward to it next year! Incidentally, Doug, mysteriously there seems to be an assymetric kite in our sail wardrobe...
