Thanks for posting that.
I have to confess I have mixed feelings when watching these types of videos. Part of me says cool boats, cool sailing. Another parts feels a little bit of disgust. It is like they are treating their boats like disposable objects to be sent to the re-cycling depot once the races/entertainment is over.
Don't get me wrong, give me the keys to anyone of these boats on a windy day and I couldn't be happier, until I crash it...
