I found this video of standup paddle boarder Chuck Patterson on Transworld Surf. Chuck writes, “The day before I shot this video, I was SUP surfing with a couple friends and 2 sharks circled us for about 15 minutes. The next day I decided to go back out at around the same time and take my GoPro camera mounted on a 10-foot pole and do some exploring. Sure enough, within 5 minutes a 9-foot shark came out of nowhere and circled twice and slapped his tail on my board before disappearing. Then a minute later a 7 ft young juvenile Great White swam circles around me for 12 minutes.”
