Foil, which allows gliding in levitation above the water thanks to a fin, is the new star of water sports disciplines. Composed of a mast and wings, it adapts to all water sports like kitesurfing, windsurfing, or surfing. Affixed under a board intended for the practice of an aquatic sliding discipline, this system allows, by the mechanics of fluids, to literally fly above the water. Enthusiasts can stay in direct contact with the instructors on board the boat thanks to a helmet equipped with a Bluetooth headset.
