AWP system brings major benefits: increased performance, easier practice and longer lifetime for large sails

• The performance comes from a better airfoil shape which is thick and asymmetric: we compare to the best soft sails on the market.
• The performance of ADD Modules compared to rigid wings comes from its ability to twist : A sail’s angle of attack is the angle it forms with the wind … and the wind changes strength (+10% at 10 m) and also direction, depending on its height.

• Aircraft wings are efficient but operate at constant altitude.
• Our wingsail is semi-rigid and allows easier exploitation and handling: for example the wingsail folds in complete autonomy on the folding lines determined during its design.

• The wingsail doesn’t flap which means less fatigue of the components and no stress for sailors. We compared the lifespan of our wing to that of a soft sail in the fishing industry and, for the same surface area and geometry, our wing lasts 5 times longer.
