According to all the documentaries I’ve seen on sharks, including the “Mythbusters Jaws Special”, there has never been a recorded instance of a shark ramming and sinking a vessel the size of the Orca, the boat depicted in the movie Jaws.
There is one now.
A shrimp boat off the coast of Florida was circled and attacked by a group of bull sharks for four days, with the sharks ramming the boat and damaging its hull. The crew had to run pumps to keep the boat afloat. Eventually, a 14 foot bull shark broke the boat’s tail shaft, and the crew was forced to call for help. The boat later sank while being towed back to port.
