Foil profile to foil?

I am curious to know are the foils on the boats like this one in the video http://youtu.be/pTRzckkVRhg
Symmetric or asymmetric?

From what I can see in the underwater video of the hydro-foil, the foils are symmetrical, so it is totally the Angle of Attack that gives the foil its' lift.

Foils

A.B.
I can tell you the AC-45 cats have asymmetric Boards/Foils. Got a good look early one morning down in San Fran. Opened up the covers and took photos of the rams and foil box interior. The foils were designed asymmetric providing greater lift to windward. Same with the AC-72 they are not symetrical.
