Maritime English
Maritime English is the name given to the language seafarers use at sea. It combines English language with specific maritime terms and commands (for example, starboard instead of right or aft, meaning towards the rear of the vessel).
It is used so that seafarers of different native languages can communicate with one another safely and efficiently. A certain level of proficiency in the English language is required by most reputable shipping companies. Maritime English is also known as Seaspeak and Standard Marine Communication Phrases or SMCP.
