This takes a dropped-stitch type approach to another level. Inflatable true aerofoil shapes instead of a round tube. I'd imagine you could make a sail leading edge without camber inducers. Interested to see how this gets picked up.

Interesting stuff. The obvious application, as pictures on their site show, is for winging, though. It could possible replace the front bladder with a shaped front section that makes it more like a race sail.

This looks promising!

Looks cool... after windfoiling with a carbon mast for years, and just starting to windwing, I'm keen to see some wings with smaller leading edges!
