Two things are certain when you're surfing Shark Island. The first is that every time you fall you're gonna hit. And the second is that at some stage you're gonna fall.

And with six feet of water above you and just two below it's a frightening prospect. So if you don't like that sort of certainty your best advised to sit back and watch. Or better yet, take photos. Steve Jones did just that as the locals played the numbers game.//STUART NETTLE
