Within Groupama Team France, Thierry Fouchier is in charge of the tri-colour AC Class wing adjustment. He is in charge of the AC Class engine: the rigid wing, which he adjusts with several tools.
Listening It is connected to the winch and the wing and can be adjusted according to the wind speed
Systems and buttons to dynamically change the shape of the wing
- The Camber what will give power to the wing
- The Twist (the fall of the sail): Which can either be closed or open, depending on wind and speed conditions.
In its cockpit, the wing trimmer also has buttons for trimming the appendages (foils). Because in the manoeuvres, he also often regulates the inclination of the foil downwind, the time that the skipper (Franck Cammas) crosses on the other side.
He is also in charge of the jib adjustment, to relieve the grinders and essentially adjusts the sheet while the grinders adjust the traveller.
For all these adjustments, the wing trimmer uses both hands: one for the listening and one for the dynamic twist. He also uses his feet with two pedals that allow him to tuck in or shock the jib. He therefore uses his feet and hands for gybes and transfers.
