We have come a long way since the first recorded sport (wrestling) over 15,000 years ago. Today, if you can throw it, kick it, ride it, hit it (or someone), there are acountless number of activities we call sports.
Like windsurfing where a sail catches the wind to propel you across the water (or land), hydrofoil windsurfing adds a hydrofoil wing under a water-based craft to purposely lift the board freeing it from the water's surface.
