Thank you very much for yours comments, we have already new sails with battens. In the vídeo we use the first sail we designed. Now we have new sails, with battens and without it, that not have leech flapping around.
Thank you. The camera crash with a rock and fell down. But only the camera, not the land yacht. ¡Oh! my english is not good, excuse me. Here you have another vídeo of that marveus days of SW wind in our beaches.
