Each boat is equipped with a pair of T-foils, on the end of ‘cant arms’. Around the size of an ironing board, the foils on the AC75 are capable of lifting a 7-tonne boat out of the water.
Sails
As in the last Cup, the mainsail is ‘twin skin’; two membranes held together. Teams are allowed to ‘endplate’, or seal the mainsail onto the deck of the hull (or platform). This provides performance gains by stopping air flowing under the bottom of the mainsail, which detrimentally reduces the pressure differential between the windward and leeward sides.
Rudder
The AC75 rudder allows the boat to change pitch, or trim, by providing lift. This change in pitch moves the stern of the boat closer to the ground, which increases the angle of attack on the main foils. The foils provide lift, which moves the entire platform up.
