Fluid dynamicists (aero and hydro) have long described that lift is generated by the action of fluid viscosity. They acknowledge that the 'flow' is a (vector flow) 'circulating' about the foil created/initiated by a generated 'vortex' at the trailing edge due to the fluid VISCOSITY --- is what causes the 'lift'. Simplistic Energy Method physics or Newtonian Physics (inviscid flow) will always result in whats known as D'Lamberts Paradox = "0" lift.
A brief paper written to explain the viscous effects causing lift: http://www.arvelgentry.com/techs/Origins_of_Lift.pdf This brief was written to explain the aerodynamic effects that generate LIFT in SAILS but can be derived for any fluid --- just change the VISCOSITY value.
What you learned about lift in USA high schools and almost all 'sailing books' is utter nonsense; and, has been so since the time time of the Wright Brothers.
