It's hard to say because you never really see them close up, but based on the sail number and their ability, I would guess that it is Fernando Eschivarri and Anton Paz (the Beijing gold medal winners).

When I was on the RC for the 2007 Tornado NAs in Miami, we watched them come into the leeward gate - they went from ripping downwind to upwind without ever letting the windward hull touch the water. It was an amazing feat of boat handling that left everyone on the committee boat agape.

Really nice guys, too. Fernando is now driving Telefonica Black in the VOR and Anton is the media crewperson on the same boat.
