Oldie but helps to visualize how our sails may works...


As a first reflection after watching I comes with idea that
a) our sails could be equipped one day with sort of "flaps" that could increase chamber at low speeds....maybe already done ....b) how nice would be to see similar test showing our modern sails in this practical wind tunnel c) slotting leading edge could be next and easy to implement - I imagine as small additional attachment in front of our mast -made of plastic, carbon fiber !
