hi, in laymans terms...:)...sailing down wind or running can become fun if the drag is countered by enough lift/wind...consider the true wind (vertically) and your speed (horizontally) on a vector diagram... on this 90 degree angle APPARENT WIND will become the most important energy source...just like holding your hand out of a car window at 10 mph with the wind in your face at 5 mph, the apparent wind will be 15 mph...
