This lad was with a "WILD" skim board having some fun at the beach.

All to do with judgement of the water depth, when to throw the board and skill at landing on it at the right time.  After that it is up the boarder's sense of balance!!

Check out the video and see the connection between skateboarding and surfing come alive with arial acrobatics thrown in, sort of like free style ski-jumping on water!

Those guys must have strong bones and ligaments.
