Honestly never seen such sport competition live. Is surfing and wind surfing same. It is a good read I came across today.
People used to say any sport in water is less dangerous than the other, but here around thousand people surfing together is quite an interesting stuff.
Good snaps too...
Thank you @angelro surfing is lying on a board, paddling onto waves that then drive you along using gravity as the energy source. Windsurfing is more akin to sailing, the energy created by the shape of the sail from the wind passing over it is like that of an aircraft wing and once you have enough speed you can steer the board like surfing using the planing rails of your board to carve and turn. Sometimes in windsurfing when the wind is light you can gently float past the waves and then using the wind rather than paddling catch the waves and then surf the board like surfing but to do this well you have to understand apparent wind and surf with the sail as well. . .
