[2], The 'S' Foil contains the slight shape of a 's' and operates in a similar manner to the 'C' Foils, with the reverse order of operations, such that when lowering the 'S' Foil the horizontal lifting force exerted increases due to a more vertical orientation in the board. One more bit of nifty boathandling comes to light after a somewhat scary incident in race 2. With the possibility of injury, were prepared if something goes wrong.
