Here's a bit of video of a July 29 Professional Windsurfing Association World Cup race in Fuerteventura, Canary Islands. The wind was gusting to a good 40 knots (46 mph). In the heat shown, my friend, professional windsurfer Taty Frans (https://www.facebook.com/taty.frans) has the lead but unfortunately later loses it because of a bad crash. I shamelessly stole this video from Avanti Sails (https://www.facebook.com/avantisails.international/).
