The Dauntless is a fictional ship in Disney's Pirates of the Caribbean: The Curse of the Black Pearl. Other than the Interceptor and the Black Pearl it is the only other ship of note in the film. Due to its size and apparent firepower from its three complete gun decks, the Dauntless is most likely a first-rate ship-of-the-line.
