This is not superfoiling... it's supercrap. All this is a huge embarrassment. Sailing is about wind, sea, waves, nature... bouncing between jetty in a commercial harbor has nothing to do with sailing. This racing location is about as crappy as it can get: muddy water in an industrial context.
There was basically no racing with the front boat 1km ahead and half of the "fleet" not finishing. Spectators? Huh? To watch some of the best sailors of the world there was nearly nobody. If Glen Ashby comes to my local club, sailing on an Opti, there would be ten times more spectators!
And overall the quality and realization of this vid put us back 10-15 years backwards.
