Hi Marek,

Thanks for the response. At least someone who is reacting

I think, Severne has made a very nice video of how the reflex batten tensioners are supposed to work:
Nice how they show the bend curve of the battens when they are tensioned not from the end (leech) but closer from the middle.
Theoretically, I think they are right. It should move the power of the sail even more forward. How much more, I don't know, because the cambers are doing this anyway.

That's why I asked people with real practical experience.

Steve Allen was involved in the development, so it's normal that he promotes the system.

I'm rather convinced that it will help the performance of a sail. It will create a profile that gets closer to the wing of an airplane.

BUT, theory needs to be proved by practice !
