Towards the end of the film, Ellen Brody drives the boat straight at the shark and pierces it with the front of the boat. The film then goes to slow-motion mode as the shark dies its death. As the film flits from character to character, it first shows Ellen driving the boat, then Hoagie and back to Ellen again. Also Michael Caine's stunt double is on the boat and it is plainly obvious that it isn't Caine as you get quite a good look the chap's face.
