Records have started to fall in the first day of the 2014 Luderitz Speed Challenge, in Namibia as the world's best windsurfers and kiteboarders taste the power of the local wind in their sails.

The stakes are high. The harbour town of Luderitz greeted sailors with winds ranging between 20-25 knots and stronger gusts of up to 30-35 knots. After the initial tests and adjustments, the windsurfers hit the channel.

Anders Bringdal clocked at 45.47 knots to earn the highest windsurfing speed of the day. Patrik Diethelm came close with 45.15 knots on his last run. Not bad for the first day of competition.

Windsurfing sails use the power of the wind to generate forces, which push and/or pull your board forward. Let's dive into the wonderful world of wind science.

Wind generates power. We know that. All we need is to observe its behaviour both on land and in the water. And a scientific formula adds up an interesting issue: the wind pressure on the sail multiplies by the square of the increase in wind speed.

This means that if winds steps up from five to ten knots, the pressure on the sail multiplies four times. As a result, lift is created, pulling your windsurf board forward and sideways.


Dreams: where Icaraizinho and Jericoacoara meet

"Dreams" is a windsurfing and kiteboarding movie featuring Icaraizinho and Jericoacoara, with exclusive scenes of Andre Paskowski from his last trip to Brazil.

Marc Morera, a Barcelona-based filmmaker, is the man behind "Dreams". An avid windsurfer and kiteboarder himself, Morera inherited the passion for watersports from his father.

"The first idea was to make it a 3D film, but after analyzing the technical challenges involved, the need for the viewers to use 3D goggles, and the potential loss of image quality, I opted for a traditional 2D film shot with Canon 7D and GoPro cameras," the movie director explains.
