Maritime English is one of the most internationally standardised varieties of professional English in the world. The International Maritime Organization (IMO) has designated English as the working language of international shipping, meaning that seafarers of all nationalities — from Filipino deck officers to Greek captains and Norwegian engineers — communicate with each other and with port authorities in English every day. Imagine a deck officer confirming that the vessel's cargo is secured, checking the anchor before entering port, or reporting damage to the hull on the starboard side — this is exactly the vocabulary used in that radio exchange.
This makes maritime vocabulary, as defined by the Oxford Learner's Dictionaries, particularly important for anyone working in shipping, logistics, international trade, port management, or naval studies. The 20 terms on this page range from basic structural vocabulary — parts of a ship such as hull, bow, and stern — to operational terms like berth, manifest, and charter, which are used daily in ports and shipping offices around the world.
Many maritime words have also entered everyday English as idioms and expressions. On board means to agree with a plan; plain sailing means something is easy; at the helm means in charge of an organisation. Learning the literal maritime meaning helps you understand these figurative extensions.
At B1 level, focus on the concrete physical vocabulary: parts of a ship, basic navigation terms, and common port vocabulary. At B2 and C1, extend to legal and commercial terms — charter agreements, manifests, flag states — which appear in business English, news articles, and professional maritime communication.

Frequently Asked Questions
Why is English the international language of maritime communication?
The International Maritime Organization (IMO) adopted English as the working language of international shipping to ensure safety at sea. When a Filipino officer, a Greek captain, and a Norwegian pilot need to communicate about navigation, cargo, or an emergency, they all use English. The IMO has published standardised phrases — the Standard Marine Communication Phrases (SMCP) — that seafarers are expected to know. This means English maritime vocabulary is essential for anyone working in international shipping.
What is the difference between port and starboard?
Port is the left side of a ship when you are facing the bow (front). Starboard is the right side. These fixed directional terms are used instead of "left" and "right" because left and right change depending on which direction you are facing. Port side lights are always red; starboard side lights are always green. A simple way to remember: port and left both have four letters.
What does a ship's manifest contain?
A ship's manifest is an official document that lists all the cargo on board, including the description of goods, their weight and volume, the shipper, the consignee, and the port of origin and destination. It is also used to list passengers and crew. Customs authorities in every port require the manifest before clearing a vessel to unload. An incomplete or inaccurate manifest can result in delays, fines, or seizure of cargo.
What is a flag of convenience and why is it controversial?
A flag of convenience means registering a ship in a country different from the ship's owner's nationality, typically to take advantage of lower taxes, less strict labour laws, or weaker safety regulations. Panama, Liberia, and the Marshall Islands are among the most common flag states. Critics argue that flags of convenience allow shipowners to avoid responsibility for seafarers' welfare and environmental compliance. Supporters argue they enable efficient global trade.
What is the difference between gross tonnage and deadweight tonnage?
Gross tonnage (GT) measures the total internal volume of a ship and is used to determine port fees and crew requirements. Deadweight tonnage (DWT) measures how much weight a ship can safely carry, including cargo, fuel, fresh water, and stores. When people talk about a ship's "size" in trade news, they usually mean deadweight tonnage. A vessel might have a high GT but a low DWT if it is a passenger cruise ship with many cabins but little cargo space.
What does charter mean in shipping?
In shipping, charter means hiring a vessel from a shipowner for a specific purpose. There are several types: a voyage charter hires the ship for one specific journey; a time charter hires the ship for a fixed period; and a bareboat charter gives the charterer full control of the vessel, including responsibility for crewing and operating it. Charter parties — the contracts that govern these arrangements — are a specialised area of maritime law.
What maritime words appear in everyday English idioms?
Many common English idioms have maritime origins: "at the helm" (in charge), "plain sailing" (easy progress), "on board" (in agreement), "batten down the hatches" (prepare for trouble), "know the ropes" (understand how things work), "give a wide berth" (keep away from), and "in the doldrums" (low and without energy). Understanding these idioms is easier once you know the original nautical meaning.
What is ballast and why do ships need it?
Ballast is weight carried in a ship's hold to maintain stability when the vessel is not fully loaded with cargo. Without ballast, a ship riding high in the water could be dangerously top-heavy and vulnerable to capsizing in rough weather. Most modern vessels use seawater as ballast. However, ballast water taken on in one ocean and discharged in another port can introduce invasive species — this is a significant environmental concern regulated by international conventions.
What is the IMO and what English proficiency is required for seafarers?
The International Maritime Organization is a United Nations agency that sets global standards for the safety, security, and environmental performance of international shipping. Under the STCW Convention (Standards of Training, Certification, and Watchkeeping), officers on internationally trading vessels must demonstrate English proficiency sufficient to perform their duties — reading technical documentation, communicating with port authorities, and using VHF radio. In practice, this means working B1–B2 English for most deck and engineering roles.
How is maritime vocabulary relevant to international trade and logistics careers?
Over 90% of world trade by volume travels by sea, which means maritime vocabulary is relevant far beyond actual seafarers. Freight forwarders, customs brokers, logistics managers, supply chain analysts, and international trade lawyers all work with maritime terms daily. Understanding words like manifest, charter, berth, draft, and tonnage is essential for reading shipping documents, negotiating contracts, and communicating with ports and shipping lines in English.
