Foiling in the hands of the Olympians

There has been a lot of digital ink from the sailing punditry community on how foiling is going to change sailing. No longer are we to bash and pound, or surf and plane, but rather fly... that is the future! So without further comment, let us observe how the Olympic Nacra 17 and their professional sailors play the foiling game; in one of the qualifying races at the Aarhus World Championships. (Though it must be admitted, compared to the Moth, which foils all around the course, the Nacra 17 must be considered semi-foiling as it doesn't fully fly upwind.)
