Mathias: "The footage for this video was filmed during five sessions I had between January and March 2012. With temperatures close to zero degrees, filming gets a lot harder. Windsurfing in winter is a unique experience. A grey and chilly morning can turn into a perfect day on the water. Whilst most people sit in front of their TV's, you are out there braving the cold. Even after a short session you can't help but smile."
