IMvvvHO there are quite a few exceptions.
I would say that it is a good idea to choose solid designs and avoid brands that ask for premium prices because mostly of market position and/or marketing costs; expecially if one is on a budget.
By sure I would suggest not to spare on masts; probably mast quality is even more important than sail design, expecially for sails requiring 100% masts. It's easier to sense mast quality differences than to sense sail model year design differences between good race sails.

RE: Race sails

Mixing masts of brand A with sails of brand B often works adequately but not for your 'best' race sails. If on a budget a good strategy is to spend up on a race sail to cover your most critical area of operation, then buy lesser sails to cover the rest. There are no shortcuts with race sails - you get what you pay for as someone has to pay for the ongoing R&D -however due to the shorter design life of such sails I suspect that the profit margins may be lower than for freeride sails.

You forgot the revolutionary Shear Tip, with a lifespan of a few dozen sessions

RE: Race sails

NP always have so much revolutionary things... revolutionary cams, that actually are needed to solve rotation troubles... revolutionary materials, that actually are coloured or printed film, to the detriment of mechanical properties... now even revolutionary 6 months warranties on masts, that actually are needed because they can't afford standard 2 years warranties... I am so tired with NP.
What I can say is that my own race sails have smooth rotation, with their standard cams; full thickness full strength transparent standard film; and go on light responsive full carbon masts with full warranty.

Of course NP will go on selling for premium prices as long as some people will go on believing that "revolutionary" "automatic" cams are needed to achieve cam rotation.

RE: easy cam

When you say the better cam rotation is the code red 07, have you think the new rs racing with ultra cam? Have yoy ever tested before say it for code red? I'm not sure, in many magazines they say the new rs racing have a revolution cam, an automatic cam and so better (i think) than the code red

RE: Race sails

Maybe laminate materials will be the way to make battenless sails one day. Nevertheless until then I agree with G-42. As for UV resistance, if that is a problem to the point to make any trade off with lightness acceptable, then I guess that painted film is the way to go, rather than laminated materials.
Let's call things with their name: laminated film is fancy, not superior.

G-42 .... Andreas,

I think you answered your own question in the first paragraph when you pointed out the benefits of laminates in all sorts of materials and products. Whether it is related to structural strength, stiffness, creasability, elongability, puncturability ... or whatever ... but there are certain huge benefits with laminates ... so in due course ... when there is continued development, testing, refining, and identification of the properties that improve sail performance, then the laminates will be there to deliver.
Actually, my point was that laminates have all sorts of really cool benefits - I just don't see how any of them create a better all around package than straight film. Unless you change the model of spars and skin to something more akin to unibody construction, the structural properties you could achieve with laminates by creating more spatial separation between the layers don't come into play, so you're stuck with layers w/o separation doing the job of absorbing surface tension - only not as well at the same weight.

I think the laminates, b/c of durability concerns related to UV and impact resistance, have proven themselves in freeride sails. Race sails, though - I'm not sure they've arrived yet. Now if you come up with some laminate sail cloth that consists of a real light thin layer with enormous ability to absorb the surface tension, and you pair it with a couple protective layers to make it feasible to use in sailmaking, and the whole package weighs in at about the same as film with better elongation resistance - great. But I don't think that claim can be made yet for any of the materials that are used in the current 'laminate' race sails.

RE: Race sails

I just tested a Point-7 AC-1,it's really fast, good construction, easy handle. A very good sail probably better than than any of the most amous ones.
You should try one.
Cheers
