While on a sailboat trip on the ocean with Tina, the shark attacks and knocks him overboard. Before he can get on the boat again, he is attacked and brutally devoured by the shark, becoming the shark's fifth victim. His death horrified Tina, who hid under the fore deck of the sailboat until rescued by Brody's party.
Eddie's sailboat, a Marshall Sandpiper 15 catboat, is called "Tina's Joy". Universal bought two of these boats for the film. The coaming (railing) around the cockpit of the catboat is damaged as Eddie desperately clings to the boat while the sharks wrenches him under the waters.
He had sacrificed himself to save his girlfriend.
