But are they really sailing it...or just on the boat... there's a huge difference... Is it just a prop, or do they have a clue?

 

Wow...those are some boats!!

Funny enough I was a bit involved in the glider portion of that film; and it was similar - thousands of man-hours involved in setting up the shots and even to the extent of making the canopy open on the left instead of the right [because it "looks better"] and finally only a couple of seconds of film time.
