The video above is the Day 4 Highlights from the Miami OCR including many classes and the new Nacra 17.
Of particular interest is some good Finn coverage. You can see the light air technique and pumping. Of special interest for local fans is the great footage of Martin Robitaille (CVL) who is continuing to do exceptionally well with this beginning of a new Olympic quadrennium. Robitaille took 6th overall at this World Cup event.
