Just out of curiosity, Jan-Olov, what boat do you sail?

Very good webpage about physical Sail/Lift Theory Pim!

The best I have seen so far on the web!

Mikko in Finland has a very good page also with airflow computer
animations.

It´s only Navier-Stokes Lift calculations that comes close to the real
physics!

Prandtl "Lifting Line Theory" is only useful for a physical non
existing "ideal/perfect fluid" created only by mathematical equations!
