The Corona Open J-Bay water-safety crew has had a busy week. During today's Quarterfinal heat between Mick Fanning and Gabriel Medina they tracked an 8-foot shark that came cruising through the lineup, and got the surfers to safety in plenty of time. It was the second time they put the event on hold, and not a single person was complaining. In fact, they were thrilled to let the surfers have a go at the Supertubes lineup themselves. When a huge set wave nearly trapped them in the impact zone, they skillfully skirted disaster by ripping their way across the big green wall. Pretty impressive stuff. What would you have scored this wave?
