So Jamie O’Brien claims that Shark’s Cove – usually a spot where tourists snorkel and look at turtles – is the most dangerous wave on the North Shore. Our only question? Is Shark’s Cove actually a surf spot? “I advise you, if you want to surf here, don’t ever surf here,” Jamie says as only he Yogi Berra could. Good advice. Most people will leave this spot for you, Jamie.
