What is a Mate

A mate on the ship is in charge of operating and maintaining merchant boats. Your duty as a mate might vary due to the ship or vessel you are working with; however, you will mostly be in charge of overseeing the ship for a specific period while underway. You are also in charge of monitoring the loading and unloading of cargo in the ship for storage. For this, you are responsible for handling the cargo and abiding by state and federal rules and regulations. Furthermore, you will also monitor when the ship needs to be stocked, fueled, and repaired for vessel maintenance and the safety of lives and properties. When repair is necessary, your responsibility is to give directions and monitor the crew member as well as clean bridges, decks, and other superstructures. Whenever the master of the ship is not available, you are next in line to give the command and take charge of the ship or vessel.

For efficiency, you need strong leadership skills, the ability to communicate well, attention to detail, excellent interpersonal skills, and organizational capacity in this role. An average of $63,969 is what a mate earns yearly. A college degree is not required, but most mates have a bachelor's degree in Civil Engineering or other related fields.

What Does a Mate Do

Water transportation workers operate and maintain vessels that take cargo and people over water. The vessels travel to and from foreign ports across the ocean and to domestic ports along the coasts, across the Great Lakes, and along the country’s many inland waterways.

How To Become a Mate

Education and training requirements vary by the type of job. There are no educational requirements for entry-level sailors and oilers, but officers and engineers usually must have an endorsement certificate from the U.S. Coast Guard. Most water transportation jobs require the Transportation Worker Identification Credential (TWIC) from the Transportation Security Administration and a Merchant Marine Credential (MMC).


Some deck officers, engineers, and pilots have a bachelor’s degree from a merchant marine academy. The academy programs offer a bachelor’s degree and a Merchant Marine Credential (MMC) with an endorsement as a third mate or third assistant engineer. Graduates of these programs also can choose to receive a commission as an ensign in the U.S. Naval Reserve, Merchant Marine Reserve, or U.S. Coast Guard Reserve.

Nonofficers, such as sailors or marine oilers, usually do not need a degree.


Ordinary seamen, wipers, and other entry-level mariners get on-the-job training for 6 months to a year. The length of training depends on the size and type of ship and waterway they work on. For example, workers on deep-sea vessels need more complex training than those whose ships travel on a river.

Licenses, Certifications, and Registrations

All mariners working on ships with U.S. flags must have a Transportation Worker Identification Credential (TWIC) from the Transportation Security Administration. This credential states that a person is a U.S. citizen or permanent resident and has passed a security screening. The TWIC must be renewed every 5 years.

Mariners who work on ships traveling on the open ocean require the Standards of Training, Certification, and Watchkeeping (STWC) endorsement. Regional U.S. Coast Guard offices provide this training, and it includes topics such as first aid and lifeboat safety. The STWC training must be completed every 5 years. Mariners who work on inland waterways and the Great Lakes are excluded from the STWC endorsement.

Most mariners also must have a Merchant Marine Credential (MMC), which they can apply for at a U.S. Coast Guard regional examination center. Entry-level employees, such as ordinary seamen or wipers, do not have to pass a written exam. However, some have to pass physical, hearing, and vision tests, and all must undergo a drug screening, to get their MMC. They also have to take a class on shipboard safety. The MMC must also be renewed every 5 years. More information on MMCs and endorsements is available from the U.S. Coast Guard National Maritime Center.

Pilots are licensed by the state in which they work. The U.S. Coast Guard licenses pilots on the Great Lakes. The requirements for these licenses vary, depending on where a pilot works.


Crewmembers can apply for endorsements to their MMC that allow them to move into more advanced positions.

Wipers can get an endorsement to become a Qualified Member of the Engine Department (QMED) after 6 months of experience by passing a written test.

It takes 3 years of experience and the passing of a written test for an ordinary seaman to become an unlimited able seaman. However, several able seaman endorsements below the level of unlimited are available after 6 months to 1 year of experience, depending on the type of ship the seamen work on.

Able seamen can advance to become third mates after at least 3 years of experience in the deck department. This experience must be on a ship similar to the type they hope to serve on as an officer. They also must take several training courses and pass written and onboard exams to receive the third-mate endorsement on their MMC. The difficulty of these requirements increases with the complexity and size of the vessel. Similarly, QMEDs can receive an endorsement as a third assistant engineer after 3 years of experience in the engine room and upon completion of a number of training and testing requirements. Experience and testing requirements increase with the size and complexity of the ship.

Officers who graduate from a maritime academy receive an MMC with an endorsement of third mate or third assistant engineer, depending on which department they are trained in.

To move up each step of the occupation ladder, from third mate/third assistant engineer, to second mate, to first mate, and then to captain or chief engineer, requires 365 days of experience at the previous level. A second mate or second assistant engineer who wants to move to first mate/first assistant engineer also must complete a 12-week training course and pass an exam.

Work Experience in a Related Occupation

Many pilots have years of experience as a mate on a ship. The ship should be of the type they expect to pilot. For example, if they work at a deep-sea port, they should have experience on an oceangoing vessel.

Similarly, many motorboat operators must have several years of experience working on and driving a boat.

Important Qualities

Customer-service skills. Many motorboat operators interact with passengers and must ensure that the passengers have a pleasant experience.

Hand-eye coordination. Officers and pilots who steer ships have to operate various controls while staying aware of their surroundings.

Hearing ability. Mariners must pass a hearing test to get an MMC.

Manual dexterity. Crewmembers need good balance to maneuver through tight spaces and on wet or uneven surfaces.

Mechanical skills. Members of the engine department keep complex machines working properly.

Physical strength. Sailors on freight ships load and unload cargo. While away at sea, most workers have to do some heavy lifting.

Visual ability. Mariners must pass a vision test to get an MMC.
