Captain Molyneux captains the Prophetess, the ship that Adam Ewing sails on. Molyneux isn’t as cruel as his first mate, Mr. Boerhaave, and he allows the Moriori stowaway Autua to stay on his ship after seeing Autua’s prowess as a seaman. Nevertheless, at the end of the day, Molyneux mostly cares about money, as demonstrated by his willingness to ferry goods made with slave labor.
