Skier/surfer/snowboarder/(insert extreme sport here) athlete Chuck Patterson recently added the video above to his Vimeo channel. According to Patterson’s video description he had encounters with multiple white sharks while SUP boarding the day before this video was shot, so he decided to bring his GoPro camera with him mounted on a 10′ pole. Patterson estimated the great white in the video to be about 9′ in length and wrote that he encountered another smaller white shark a minute later.
