The IMOCA 60 class, originally a non-foiling offshore racer competing in around the globe races such as the Volvo Ocean Race and the Vende Globe was re-designed with S shaped daggerboard foils. Subsequently, Garth and John Ilett in Perth, Australia developed a two-hydrofoil system for the Moth with active flap control for the main foil via a surface sensor. Sailing the boat in subpar wind conditions proved to be easier and more enjoyable than a Waszp or Moth as the catamaran hulls provided increased stability. On catamarans, a single main foil can be attached between the hulls just in front of the center of gravity and at 2 degrees of incidence, spanning the tunnel with supporting struts. This method is most similar to how the 49ers set, in this case demonstrated by Kohlhoff and Stuhlemmer. When the board starts at its maximum height above the water, it is near vertical and employs a lifting force normal to the exposed surface or otherwise horizontal lift.
