What language must a Third Mate be fluent in?

A Third Mate must be fluent in English because it is the international language of maritime communication. The ability to understand and communicate in English is vital for safety and effective operations on the vessel. This proficiency ensures that directives, navigational instructions, and emergency communications can be clearly understood among the crew and with other vessels, ports, and maritime authorities.

In the global shipping industry, English serves as a common language that facilitates interaction across diverse nationalities and language backgrounds. Consequently, the mastery of English not only aids in operational efficiency but also enhances safety by preventing misunderstandings that could lead to accidents or mishaps at sea.
