I surf at the highest tides. Though a complex game
yes I like it because  Surfing is a surface water sport in which the wave rider rides on the forward or deep face of a moving wave
Dyes it take technique to engage  in? 
No special technique buddy, just look for a  wave to  carry you  the surfer towards the shore
So how do you surf, do you float and glide along on to be tossed by the raging sea? 
well im not sure about that but  the waves for surfing can be  found in the ocean, but can also be found in lakes or in rivers
Do you use a surfing board? 
Yes. Also artificial wave pools can also be used 
Is it an Olympic  sport? 
No. Actually  surfing refers to the act of riding a wave, regardless of whether the wave is ridden with a board
