A day after two separate shark encounters while out SUP (stand up paddleboard) surfing, big wave surfer Chuck Patterson decided to go back in the water the next day. Crazy, right? This time he armed himself with a GoPro HD to capture everything on film. And that he did. According to Chuck, the second shark, a ~7-foot Great White aka Landlord aka Grey Suit, circled for roughly 12 minutes before swimming away.
