If Google didn’t help, all these explanations likely won’t either.

Next time you’re out for a drive stick your arm out the window. Ta-da! Your body is the sailboat and your arm is the sail. Now experiment with turning the direction of your hand and feel the pressure differences and how your arm is pushed around.
