Question: Here's a question that's never been answered. After Captain Quint addresses the Amity city council, he bids them good day and leaves, and a dog and a little guy wearing a cap obediently follow Quint down the hall. For a split-second, we also see this little guy's cap pass before the camera inside Quint's dock-front quarters. Who was this little guy, Quint's first mate? We don't know, because that little guy is never seen again after the dock quarters scene.

Chosen answer: The man is never identified. It is never stated in the movie that he is Quint's first mate or that he works for him. He could be or may just casually know Quint, and is probably also a local fisherman.
He is Quint's deckhand/first mate. The fellow who was cast was not an actor, just a local character, whose dog followed him everywhere (Spielberg got a kick out of him and cast him). This was clarified in a scene where he quits rather than go on the boat after Jaws, which was cut out of the film but can be found on YouTube.
Answer: I believe you see the same person helping prepare the Orca before it starts setting out. He has Quint's M1 slung over his shoulder.
