<Nice how they show the bend curve of the battens when they are tensioned not from the end (leech) but closer from the middle.
It look like commercial trick. If batten place in pocket and stretch it, picture will be not same like in video. Then extra increasing batten tension in regular sail it not make profile deep, contrary to this that make S-shaped profile.
Sorry for my English
