Sails and aerofoils

As a windsurfer and physicist, the aerodynamics of aerofoils are important to get right.

At the most basic level, modelling molecules with Newton's laws will get you the right result when simulating an aerofoil. However, an aerofoil does not simply deflect air downwards.

Actually this is hard to describe unambiguously, I can see why there are arguments.
