For example, "captain" is a synonym that carries a more formal tone and suggests greater responsibility and authority. "Pilot" is a synonym that suggests specialized knowledge and skill in navigating a particular region or type of ship. "Boatswain" is a synonym that emphasizes the practical duties of overseeing crew and equipment. Other potential synonyms include "navigator," "coxswain," and "steersman." Ultimately, the choice of synonym should depend on the desired connotations and context of the conversation.
