chunk: Quint, Brody, and Hooper set out on Quint's boat, the Orca, to hunt the shark. While Brody lays down a chum line, Quint waits for an opportunity to hook the shark. Without warning, it appears behind the boat. Quint, estimating its length at 25 feet (7.6Â m), harpoons it with a line attached to a flotation barrel, but the shark pulls the barrel underwater and disappears.
