ABC: What is so different from traditional sails?
HS: Externally and aesthetically few things, the differences are inside, in fact wea double surface which creates a "strange" thickness on the sail that looks like a pocket of very large tree, in practice you do not see the classic depth but almost convex surface.
We were able to achieve, for windsurfing, a wing sail similar to other modern wing surfaces designed for boats and catamarans.
Obviously our wing sail is a weapon as a traditional sail, mast and boom as standard

does this mean there are no cams?

I think there are cams in the sails but two batten per cam, this technology may go no where or change windsurfing forever especially formula slalom and SPEED sailing.

Choco, Nice find although apart from possibly HR Puffinstuff I've never seen a tree wearing pants with pockets. Those formula sailors will be wetting their plants too.

Gaastra did this in 1986.

good to see they revamped an old idea

In appearance - not unlike the fixed wing sails used in Americas Cup

^ I know of guys that have done that with race sails and also used cut up pool noodles.

Aeroforce sails from San Diego sold similar sails, late eighties and actually called them....Double Luff Sails!

Double luff sail looks a mission to use, when weighted with water.

Has anyone ever tried inserting inflatable/deflatable bladders, inside deep luff pockets, to displace water?

Sounds like a double luff fail.

Dan Kaseler did this: olypen.com/dkaseler/Inflatable%20Gallery.htm
not exactly what you asked for but similar.
