Kelly Slater || Kelly's Wave
During the past 10 years, pro surfer Kelly Slater and his team have been secretly working on what they now claim to be the world's best man-made wave. There's very little information about the facility at the moment, which was constructed and designed by the Kelly Slater Wave Company, but in the video below you can see it in action. The technology could potentially cause a huge shift in the sport, allowing athletes to train all day every day without having to worry about sea conditions. Check it out below.
