What creates the pressure difference? The sail should deflect the bottom half of the flow into a narrower channel, causing a faster flow with a lower static pressure. Yet, the top half of the flow is somehow of a lower preasure. What I'm saying is, I don't get the physics.
It's called 'Wind Tunnel' and it's on my iPad. I think it's a great little teaching aid for beginner sailors. Note that any shape you draw will be solid rather than 'flappy' like sail cloth.
