Here's the link to the SailGP regatta last weekend in Saint-Tropez France. Lots of wind lent to the class boat-speed record being set several times. This was more wind than they've raced in before and you can see the boat handling changes, "landing" boats before mark roundings to scrub speed into the turn. The races themselves are under 14 minutes long, but there is also interesting insight to be heard from the commentary before and after races.
10 kph = 5.3 knots = 6.2 mph
