Ok, have you ever been in a sail boat?

No.

Well you must try it.
Your doing a tack with the sail fully stable suckin'
energy from the wind, cuttin' water and bouncin'
waves off the starboards, that's the sound you hear.

Next, you reverse tact and the sail flutters (stalls)
until re-acquistion of stability going in nearly the
opposite direction and you're still heading into the
wind, so the net motion is into the wind. Every pilot
should do that. I was on trapeze, with a good fat old
captain on the til, and me being a skinny lively bitch
loved jumped to either side of the boat, pulling the
sail to max the energy out of the wind.
