Maybe a candidate for caption competition. First suggestion "Brainless moron".

I think it should be titled "Windsurf Board Almost Broken By Cliff Jumper"

It's gotta be the sailors fault !!

We should all be used to looking up for crap falling from the sky with so many kites around these days

You've always got to be on the lookout for drop bears...

Seriously though, what a shock for the windsurfer to suddenly have something huge barrelling out of the sky at you.
And a shock for the jumper who was too stupid to "look before you leap".

A narrow escape for both of them.

Unfortunately the diver failed to make it as a finalist in this year's Darwin Awards.

I think this should go under the topic of "Staged Diving"
