How does it work?
Using the natural power of a river, the system enables you to enjoy surfing together with your friends. The idea is to divert a river’s flow by a pulley and an underwater sail to accelerate the surfer. And this is how it works:
The system consists out of three parts a sail, a pulley and a rope connecting the surfer and the sail and requires minimum two persons. The pulley needs to be attached to a fix point (e.g. a bridge). Once in the water, the surfer drifts downstream and the sail on the other end of the rope gets dragged upstream towards the pulley.
