That looks like a rebadged proboom. I wonder if Proboom will be making their booms.
Gee the leach fulls away a lot at the very top.could be the Foto angle.all the hallmarks of a point 7 sail.they look fast.
The bottom luff sack looks huge.Good bottom end.

The black would still scare me in sunny hot australia, I wouldn't want to be the guinea pig on that one. Curious about how the air cams work?
I believe that is not so much of a concern for sails. Severne is doing black sails and when I purchased these I asked the same but they said it's not an issue. For boards it's obviously a different story and certainly an issue although leaving any board out in the Aussie sun is probably a terrible idea.
For these sails, I guess if the seams are glued instead of sewn, we have to see how durable these are in the sun but guess North has experience with this in their yachting sails?

I'm not too worried about the sun mine's been out in it quite a bit doesn't seem to get hot to the touch.(Baja)
I'm pretty much a hump and dump kind of equipment guy don't baby it or don't rinse it.
Just to be clear there are no seams at least on the wave sail the only stitching is the mast sleeve to the sail.
There are no glue joints.
like Gwarn, i generally don't rinse anything and everything i own cops a lot of sun.
should the sail last at least as long as my other sails, it's a real improvement overall. So far it appears to be a "one sail" solution for my needs
I'm using it on a hot sails mast rdm which i believe is somewhere between flex tip and constant curve. Same mast I used on my neil pryde and other sails

While on a windsurfing trip in Cape Verde last week saw the North crew testing the race sails paired to some brand new isonics. First time seeing 3di in flesh, impressive details, no seams, aero cambers. Nice masts, booms, all carbon, everything North
Wind was light that day, 15-16 knots, but boy they were fast
Few pics taken
Nice pictures ????. The specs on the 7.7 Freerace look very mysterious. a 370 mast to a 7.7, that can't possibly be right
I recently got to try the Wave 5.3 and the X-Over 5.4 in about 15-20 knots and head high waves over 2 days thanks to a North ambassador. I thought the feeling of both sails was very nice. Smooth, never twitchy, easy power delivery. The Wave struck me as a cross off sail perfect for Pacasmayo or One Eye or similar. But the X-Over was far better for me. It's definitely more powerful, and I felt that I was planing easily without having to pump the board onto the plane. In power delivery I thought it was very similar to other power wave sails I've used such as Goya Banzai or Severne Blade, but I'd say it has a softer feeling than those sails without being less powerful. Has a very natural feeling in a straight line, very comfortable over the the bumps. I felt I could sail longer without getting tired due to the light feeling of the sail. I never felt like I was fighting the sail even in stronger gusts. In the waves it goes completely neutral on the top turn. I only have one criticism, and that is the window is too low (I'm 6'2) and ends too far away from the mast. I couldn't see the wave mid bottom turn, only right at the beginning and end of the turn. Shorter people should have no problem with the window position, but it really bugged me. It was the only reason why I wouldn't buy one.
Rigging was really easy. Downhaul by hand. The downhaul specs were a bit off, the sail looked great and performed perfectly with less downhaul than recommended (I used my own Goya mast and boom and Streamlined extension). Maybe with the recommended mast it will rig to spec?
I've try the North Wave 3.7 in bump and jump condition, rigged with a Maverix mast. Well I am really stoked, but know is time to test my new Blade pro 4.2 2023 (carbon fusion) and we will see.....Both sails are a real step in the future.

being much shorter than you, the height of the window was no problem for me, but i do agree that on the 5.4 X-Over it does end too far away from the mast. on the 4.7s i tried i didn't have that issue.Select to expand quotephiln said..

they did for me. bang on.
in fact, i didn't feel much difference varying the downhaul ~1cm.
outhaul changes were quite noticeable though.

I have lots of unanswered questions about these sails
-snip-
Thansk for all the info on this thread, I'm in the US and there is zero info on these. I have a lot of experience with their yacht sails and love the 3dis, but will for sure be waiting to see what others think before getting a WS sail.
prior to "official launch" they were keeping a lot of the info on the sails under wraps worldwide, not just in the the US.
but as of today the sails are now officially announced, and lots of info is provided via the videos (as you scroll down the page):

Also very curious to see
-snip-
whether North is going to insist on specific masts for their different sails, as they're probably not designed to set up on other masts.
that is correct. the fact that they are designed for MDM masts pretty much precludes use on other brand's masts (which are generally RDM or SDM); also from what i understand based on data i've seen (not officially confirmed), they're bend curve is pretty unique.
that said, this isn't unusual. when it comes to race sails of any and all brands, in order to get the performance the sail is designed for, one pretty much needs to have the manufacturer's mast. in some cases - cough, Duotone/NeilPryde and likely others too, cough - one even needs to have the sail and mast vintage be the same or fairly close to get the match.

Do you insert and remove the air cams each session?
The video showing how to rig the slalom sail shows it stays in place.

Hopefully not, although one wonders why it does not ship with the air cam installed ... i love when he says that "it is easy"!!!! 
I wonder how the rest of the rigging procedure goes, the usual thread in the mast and then push/pull/cajole the cams in place and then (finally) inflate?
Nice price in the USA by the way. $1479 (5.2) to 1649 (8.6) and FREE SHIPPING!!!!!!

Ah no, the mast threads into the cams. That is VERY nice, as easy as with a no cam sail. And you leave the air cam in, it rolls with the sail. There are double battens at the double sleeve, at the cams, and they are adjusted independently of the single batten that takes you there. Must admit: all this makes any other race sail look a bit obsolete!!!!

negative. just initially. which actually answered one of my questions ("what happens if the air cam punctures?").Select to expand quoteduzzi said..

probably to prevent potential damage.
sails get rolled and packed pretty tightly for boxing/shipping, much more tightly than we do on a regular basis.Select to expand quoteduzzi said..

someone i know that has ridden some of the final preproduction models (with different test battens) tells me that yes, the rigging and derigging are as easy and straightforward as depicted in the videos. (he also noted sails are very powerful for their size but feel light in the hands, have really good handling, and excellent rotation).
as for the tuning, yeah: tuning batten tension in the back part of the sail separately from the double luff area is a neat trick, and then adjusting cam pressure via air pressure too? wow!
i'll report more when i get my hands on one.
What is the point of the air cam? What advantages do they have over standard cams? It seems like a lot of stuffing around.

Which might be a problem? It beats having the thing sink into the water but a wing shaped floating surface could make for some long swims to try to catch it, if you fall and get separated.
Other than that the inflatable sock might stabilize the leading edge? On a normal cam the only thing that gives shape to the area is the tension induced by the mast, batten and the cam ... although there is a lot of it!

The inflatable cam bladder system could potentially result in more refined leading edge profile
Search YouTube for "MWsails", their website is MWsails.com.
They have been using a similar inflatable cam system for a while with a USA patent (not Europe).
Looks to me like NS have a similar but massively improved system.
It's a very different product to the current competition. Is it better / faster is the big question.

Read on another forum that they are very quiet compared to monofilm especially when pumping
Pretty revolutionary and good to see some developments in our sport but as soon as I have to use a pump I'm done, sorry. Maybe if that means no mast in the future I reconsider but unlikely 
yes, good to see innovation, but wouldn't say others are now obsolete.
just one example: Duotone's hyper cam 2.0 (of course designed by the guys who previously developed and marketed their sails under the North Sails brand name...) allows finetuning of the pressure on the mast of each cam individually, which the air cam system doesn't seem to allow. of course, the air cam system may have different benefits.

Have you had much experience with 3di?
A one-design class is doing rounds with Quantum and North sails in my area, I've had time to observe both during the past 5 years.
.
How can you have seen these for the past 5 years if the first sail with this material hit the market not even 12 months ago?
These sails were never employed in the one designs project.
