It's all about the angle. You can achieve the highest speeds when the wind is actually coming from right angles to your desired direction of travel. You start out with your sail angled a little bit, acting like a wing sticking straight up. The wind lifts your sail/wing forward. As you gain speed, you trim the sail to keep its angle of attack from becoming neutral to the new "perceived" wind that the sail sees.

I saw this funky car in a 1980's Popular Science. It was on the cover.

Lead or follow. Either is fine.
