This pub sounded like a bit of nightmare on Elm Street (where the New Elm Road is now, off Water Street). The Navigation was next to an abattoir and it was open all hours and "the killers (slaughterers) used to send nippers in with cans for their beer ." Oddly enough, it was also popular with courting couples, "If anybody in the area wanted to be out of the way with a young female, the Navigation was the ideal place to be because it was down in the Potato Wharf ."
