Hi All,

Tried the new sail NeilPryde RYDE 2022 7.2 few days ago and ran into the issue below...

According to the specs here www.neilpryde.com/products/ryde-2022
Luff is 464 and the extension with 430 RDM mast should be 34 and the boom is 199

During rigging it turned out the correct downhaul (where the borderline of the loose leech on the sail is between min and max marks)
is at the extension setting 22 and the boom is also much shorter than 199 (can't remember the exact setting - something like 182)

I really struggled to set the downhaul at 34 and was sure the mast or the sail was going to break.
Also, with the boom it sort of obvious what the length should be and if I set it at 198 the sail does not reach the back of the boom.

Just wondering if anyone came across similar issue or has any idea what could go wrong

It does not inspire much confidence to buy incorrect equipment (e.g. wrong mast length) based on incorrect specs

I had a similar issue with my 6m Ryde when I bought it a few years ago. Initially, the boom was far too high for my harness to hook into and I was unsure as that I had the down haul in the correct position. Eventually I lowered the boom to the bottom quarter of the space and set the downhaul and outhaul so that they looked right. This worked out really good and I have found that the Ryde is a great sail in all respects

It was explained to my by someone in the business, that they (the designer) have to come up with the rigging specs before production of the sail so the specs (mast extension/boom) can be printed on the sail. In my somewhat limited experience (7 sails), most of the time they get it right, or are close, but sometimes they are off. Just part of the manufacturing process for sails. And in the best case, those numbers are recommendations anyway.

As long as the sail can be rigged properly, to perform as designed, you should not worry about it, though I once did for a sail I bought.

What mast are you using?

You can use that 430 mast with 22 cm of extension on that sail, right?, so what is the problem other than the specs being off? Now if you had to go to a 400 mast, that would be a different story.

But I agree those setting are way off, maybe someone entered the specs for the wrong sail/wrong size sail?

Not a huge problem in my situation other than remembering the settings for this particular sail
With the other sails I just dial whatever is on the bag and it fits perfectly - that's why I was thinking I was doing something wrong with this one.

Under other circumstances I could be in a situation where I already bought 460 mast that would not work on this sail (although it should have)

And I don't have confidence anymore which mast to buy for any other sail (e.g. 8.2 ryde or speedster) based on this experience

Those dimensions are the same as my 6.7m Hellcat, are you sure its a 7.2m sail ?
On their website those dimensions are from the Ryde 6.7m.

Tried rigging again in the garage: base is 22; boom 192 - long way from 34 and 199 as per the bag

I'll check with NeilPryde WTF

That was my 1st thought as well. Those printed dimensions are way out for the 7.2m to be some "pre-production" measurements. Perhaps someone at the factory put the wrong dimension template (of a 7.2m) on the panel of the sail of a 6.7m. Is that the only place on the sail with the sail size on it? The sail bags usually have the sail size on them. Does that say 7.2m and does your sail have a bit of spare space in the bag?

A local here has a Duotone x-type 6.6 with the luff length of the 7.3m on the dimensions. But at least it is a 6.6m.

I have just bought a 2023 Ryde 7.2 with 464 luff and 199 boom. The sail rigs exactly to spec with 34 extension and 198 to 200 boom length. The sail pulleys were downhauled within a 1cm of the extension pulleys. Is there a chance your Ryde 7.2 is in fact a 6.7 as previously mentioned by another in this thread? Rig it up and post a photo.

Goes to show you that you can use the printed numbers ONLY as a rough starting point. Then rig it correctly and keep a rigging chart of your own. I have been doing this for all my sails for 40 years. I don't trust anybody else's numbers except my own.

7.2 size and the same specs are written all over the bag and the sail and the serial number looks like 7.2 as well

Could be a factory mistake you are right

I'll check with NeilPryde

Definitely sounds like the sail is smaller than 7.0. All the 7.0 sails I have used in the last 10 years required a boom around 200 cm, and extensions usually where at least 30 extension for a 430 mast. To fit 7.2 square meters into 192/452 would require a shape that looks more like a square than a windsurfing sail.
Sounds like a mix up at production.

Pretty sure the 7.2 2022 model prefers the 430 SDM over the RDM. I know the stiffness and curve are supposed to be about the same but they are not.

That's what I was thinking at first as well - maybe SDM will work better

But now I'm thinking the curve on SDM could be different but not the length!

Also on NeilPryde website for that sail, RDM is the first choice.

I have been using a 430rdm on the 2023 7.2 and it sets beautifully.
