I have just ordered a 33i with the spinnaker/asymmetric package. It comes with pole/sheets but no kite.
Whilst I have the j and i measurements to workout what size of kite I need I cannot tell if the spinnaker halyard sheave is at the top of the forestay or at the masthead on the non performance rig.
Does anybody know?
Has anybody the measurements for the 100m2 recommended spinnaker?

I have just ordered a 33i ... Has anybody the measurements for the 100m2 recommended spinnaker? I find it hard to believe that size when the 36i Performance rig plan & inventory says the recommended symmetric spinnaker size is 98m2, and the 36i standard rig = 90m2. |

It too struck me as on the large side but that is straight from the Jeanneau literature. 100m2 for the performance mast too.

Either wait and see. OR, go for one or the other, and if you go for mast head, and there is not a ring up there, the dealer should be able to install something that would work.
Reality is, it is the typically the sum of SPI which can be from 0-6"/10cm taller than the I for the jib/genoa, the foot will typically be 1.8 times the J measure. So boats do go for a bit more, and increase the spin pole accordingly.
If doing an Asymmetric, same base measure per say. Or you can put a prod/bowsprit on your boat, and if you extend out say 3'/1 meter, your J measure increases by this amount, so you can put a bigger spin on your boat.
If the normal spin height is to the ib hoist, say 3/4 of the way up the mast, many will put a hoop at the top, to gain that say meter or two height, add a prod, and the spin size is potentially doubled depending upon how the spin is designed!
Some that race will also max out the size so they are not negatively handicap time effected. My boat based on J and I measure max spin is 695 sq ft per the local rules. If I bump to 725, ie what Tony Castro designed the boat to have, my base time would go down 3 secs a mile, so I would have to sail faster both up and down wind this speed in order to take advantage of this larger spin!
For cruisers this issue does not matter. Some might as I did initally when I bought the boat, had the spin made about 10% smaller than max per say, so if spouse and I got caught with it up in too much wind, while not saying easier to handle, the"eek" factor would occur a bit later. Yeah not as fast in lighter winds, but one gains a few knots in the upper wind range before going EEEEEEEK!
If you sail where the wind is lighter generally speaking, max it out. If on the windier side, going a bit smaller might be the better answer, if it is just you and a spouse. If a crew racing. all bets are off as to how big, or a BIG that is masthead in height, and a smaller one that is at the top of the jib. Locally a few folks have both. Rated for the smaller height hoist, but take the penalty for the MH kite, as it more than makes up in speed down wind for the upwind hit that also occurs.
There is not at the end of the day a right or wrong per say. Only what works for how you sail and where.

Thanks for the tips.
Unfortunately waiting is not an option as the first race is two weeks after delivery and every sailmaker in the UK is always snowed under at that time of year.

You could ask your dealer - they will be able to ask the factory if they don't know.

hmmmmmm...... you race, and you bought the non performance model?!?!?! but most of the other goodies?!?!?!?! I'm confused! thats ok too!
Hopefully the dealer, manufacture can get you some info. maybe even the spar builder. Is it too late to buy the P mast etc? maybe them you can get the info as to where the spin halyard goes to, or order two, one for the top of the jib area, one for the top of the mast! I know I know, like money is mad on trees eh!
Something seems like it would be easier to figure out than this! Then depending upon the race/distance etc, Could you do an FS/white sail division vs FS/Flying Sails?!?!? we have those locally, my most recent was an NFS, so using a spin was out! glad of that too, winds in the 12-20 range, with a squal that came thru with 30 knot winds, and only 3 crew!

The performance package was what I wanted but Jeanneau refuse to supply it with a shoal draft keel. I have to have the shoal draft keel due to restrictions on neap tides where I race.
Looks like ill just use the I dimension and order the kites from that.

The size issues are similar on our 30i, specifications say 75m2, which seems very large. Sailmaker agreed and recommended 50m2 based on his computer design and our measurements. Our spin halliard is just above the forestay, not at mast head. I hauled up a tape and measured mast block to tack and sheet blocks, and measured tack block to sheet block. Resulting asymmetric sets beautifully with no tweakers or other gear. Interesting that luff is over 1 m longer than head to tack block measurement, and the sail sets on a curved surface much larger than the flat triangle would suggest.
We have found that even in winds low as 2 kts, it brings our speed up to where true wind of 150 deg becomes apparent around 60 deg, and heel force soon becomes limiting as wind strength increases, but it collapses at much less than 2. So useful wind angles seems to be only to about 120 deg true. A code zero or similar reacher on a furler like shown on recent posts might be much more versatile, unless you plan to have both.
It is possible that the larger sail would work, especially with racing crew, but as my wife and I sail only 2 up, we are very happy with our smaller sail, which is still well above our previous experience to get up and more importantly, take down.
It does not fit with the racing schedule, but like MartyB, I would wait until you can measure and base your decision on a discussion with your sail maker (or two) and decide on basis of a specific good design.

Yes had the same answer when we ordered our shallow draft 39i - I believe this is because the stability calculations for the CE compliance have not been done - so it is a legal rather than actual concern that the heavier ballasted shoal drafts could not take the larger rig |

From memory, it is just above the forestay/jib halyard - definitely not at the mast head. I provided J, I figures to local sailmaker (Saturn Sails - Largs) for quote Cruising chute. They are suggesting 58.5 sqm. sail.
Still trying to make up my mind whether to fit removable bowsprit - waiting response from email enquiries.

Thanks for that appreciate the advice. Spinnaker now ordered from the I and J measurements. Gone for max size and then a smaller asymmetric. Probably going for a continuous Furler on the asymmetric so a sprit may be in order.

Came v. close to buying a 33i this Winter. I intend to buy one sooner or later and would welcome the opportunity to listen to advice about purchase and new ownership from personal experience. demaid@gmail.com

If you want a good deal shop around and don't tell them where you are going to keep it. Dealers are not supposed to sell to customers other areas. Good luck Ertan |
