A lifting foil having a lower trailing course having a margins and an upper leading course margins connected in a manner to enhance lift of the foil.


1. In a lifting foil wherein a coordinate system has its origin at the center-of-gravity of foil and employs 3-axis, X, Y, Z Cartesian coordinate designations wherein +Y is starboard, −Y is port, +X is fore, −X is aft, +Z is up and −Z is down relative to gravity and is subject to a −X freestream, the combination of (a) a lower configuration having a lower trailing course with a positive camber having a lower starboard margin and a lower port margin, said lower course extending sideward between said lower starboard margin and said lower port margin and be...
