Hi Kev

We have a 50sqm in our inventory which is the orginal North kite that came with the boat 8 years ago. It's meant for a 3.5m pole and it's pretty shot so we don't race with it as we have a 3m pole and a pretty decent 40sqm.

We use it for practising though and it's quite a laugh. It looks massive (and hilarious to other boats watching). It's not much quicker we don't think over most points of sail but it's a bit of a turbo boost on a broad reach in marginal planing conditions. I'd be interested to try it on a proper size pole.

We've ordered an asy too which will be ready in a few weeks. I'm looking forward to trying that out, all the advice we've had suggests that it'll be a very useful sail.

Garth - Thanks for the tips, it's been pretty depressing the last couple of weeks getting beaten by boats we were a long way in front of when it was blowing. And by weight well forward, how forward are we talking? We've been pushing people forward a bit but maybe not as far as we should!

We have had 2 newish J80s join our club this year so we havent raced against them properly. We'll let you know how we do against them.

They do look hard to beat though, they are good on the wind (much nicer in waves than a projection) and I cant see how we are going to gain much downwind due to thier large asymmetrics. We'll see....

I agree with the light downwind stuff, its difficult to hold your own due to the high surface area of the projection compared to its displacement. Make sure you reduce the transom width in the water and be patient. Look for clean air otherwise ive found the projection dies

Kev,

We rate with 48.8 sqm kite and carry 45 sqm kite - both 2004 vintage - pole lenght 3.1m.  We use the larger one up to Force 4, but do struggle a bit if it is shy.  Hyde's have suggested that the optimum size for Projections is around 44-46 sqm with 2 sqm equating to .001 IRC point.

The Projections in Falmouth consistently beat two J80s last season, but you need to take out long lead on the beat in light conditions to stay ahead downwind.

We have a 45m kite , 3.1m pole , full size genoa . Our local H'cap system , NERR , has given us a number of .977 ( same as the 06 IRC no. we had ) , after a temp no. of .9598 . Our 07 SBR is 0.882 .  The local J80 has a no. of .960 . We have completed 2 races in our spring series in winds of 10-14 knots , we seem quick upwind , don't seem to point as well as some ( rig went quite slack , we've had chainplates out and modded ) , were ahead of all 1720's except one , which I was impressed with .Struggled a little downwind , melges were planing when breeze picked up and were gone ... I hope in stronger winds 15 - 20 ? we may really pick up and go . We were well ahead of J80 on water but they got us once on H'cap .  I have info on how to set up rig but nothing on tension settings .. can anyone help ?   I also have a new Hyde no. 2 which have only had up once to try , looks v good , I suspect it may point better than no 1 in 15 + ?          have tried our no 3  !     so small  ... for 30 + knots ? must have to be really blowing to get her to work well ?      Doug . Filthy Gorgeous GBR7632R

Boats on the Forth use a PN handicap system and we've been shocked to receive a handicap of 855 for our P762 (Melges for example is 916), which appears to be courtesy Byron Software Cruiser/Racer handicaps rather than the Forth Yacht Club Assoc's own data. The translation from IRC (.977) would be 875.

Does anyone know how Byron collect/ calculate their data? We think this handicap is unfair and I'd like to appeal.

Doug, we've completed two races so far in breezy conditions (18-30knots), unreefed and using the No1 (2nd slot from back on genoa track) to drive the boat with main flapping much of the time. This way we've been both quick and pointing high. This breaks down when gusts of 25knots or more hit, as even five up we get flattened!

I'm sure that Nigel Theadom would be the man to ask re rig tensions...

Im not sure what sail area your number 3 is Doug, but most the boats i know of dont have a number 2 when they were built, they go straight to a number 3. Our number 3 is basically a blade jib and we use it in around 14 knots depending on the crew number and sea state. Last years racing i think we used the number 3 most the time, it was quite a windy year. I know many people have bought number 2's now to fill the gap in wind conditions.

The melges are very quick downwind, as are the 1720s. need to make alot of ground up to windward. the thing is that projections are not designed around downwind planing as much as the melges or corks.

Chic, your PY of 855 seems way off the mark.  Most common PY's for P762s which i've seen are around 900-905 - this is pretty fair and enables you to compete if you sail well.

We race both PY and IRC at the same time, so an immediate comparison can be made.  Our PY is 880 which is also a bit low and normally leads to us dropping a couple of result places compared with IRC.  For example, we need to be 60secs quicker on 1.5 hour race to beat J92 on PY compared with IRC, which is quite alot.

I suggest you gather the evidence and make the appeal.  Good Luck

Thanks for this info Garth, I have included your message to me as part of the evidence - we're doing a passage race tomorrow and I've been promised a new (and hopefully more realistic) handicap by tomorrow morning!

So far we've found our genoa change over point to be about 15knots+

We used the number 1 this weekend which was fine upwind but the main wasn't doing a lot. Not sure how windy it was without instruments but there was enough breeze for double figures boat speed offwind.

We used the number 3 a few weeks back when the wind was in the high 20s and it was excellent - we pointed well and had good speed. A dream to tack as well!

Thankfully we've never needed to change genoa on the water as it must be nearly impossible with piston hanks and no headsail foil. Has anybody changed mid race?

And what about kite changes - quick bareheaded drops? Or does anybody have 2 halyards and peel?

changing genoa downwind is fine, doesnt take too long. we have piston hanks as well plus a couple of spring clips.

Changing spinnaker? just keep the biggest one up you have! we dont have a reacing spinnaker, usually just run deep with kite then fetch the last bit with no kite, seems just as quick for most short races because you dont have the crew pissing around changing sheets/halyards over.
