This should be two completely seperate threads.
One about Wave sails
One about Race sails.
They are
completely different animals!!
I can see that there
could be big advantages on wave sails with greatly enhanced cloth stability, and therefore much more stable sails. Wave sails generally have a very narrow wind range compared with Race sails and, in my experience, the draft moves all over the place in comparison. And indeed, user comments here suggest that this may be the case.
On the other hand, Race sails are
already very stable and the shape very locked in. They can be made light and stable, but not very long lasting, or they can be made stable and long lasting, but no so light. Pick two and pay your money.

About the only
potential advantage I see in this tech. is the possibility of making a sail stable, light
and long lasting. Or significantly lighter, but still as good performance and durability. But that is yet to be demonstrated.
They are definitely going to be at the top of the market price wise!! So if they don't attain the
potential of being at least equal in performance/shape, and light and long lasting, there is no breakthrough. Or if they are
significantly, and demonstrably faster, and more or less equal in other respects, that
would be a breakthrough.
If they don't start winning races in the hands of sailors who didnt before, there is probably no performance breakthrough.
If they don't allow speed sailors to suddenly start breaking their PB's, same thing!
All sail brands have claimed their new Slalom/Race sails are faster every year, yet speed PB's don't necessarily bear this out. I don't think there is much doubt that Race/Slalom sails have become easier to use, and that can, and has, led to sailors enjoying their windsurfing more. But the actual speed improvements are much harder to see. Probably the area where we have seen the most improvement, is that a lot of sailors are now going faster on big sails in lighter winds as handling and stability has improved and made more difference in those bigger sails.
