What you earn and what it costs to get there.
Median
$92,460
New mate, small boat
$47,420
Master on a large vessel
$170,640
The national median is $92,460 a year, and the bottom tenth start near $47,420. One occupation code covers everyone from a harbor tour boat captain to the master of an ocean-going tanker, which is why the spread is so wide. Deep-sea and harbor pilot work sits at the top, small local boats at the bottom.
A daily rate, not a salary
Common on tugs, supply boats and deep-sea ships
Most mariners work a rotation: a set number of days on the vessel, then the same number off. Pay is usually quoted per day worked, so your yearly income depends on how many days you sail. The published annual figures assume a normal rotation.
$170,640 or more
Masters of large vessels and harbor pilots
Harbor pilots, who board ships to steer them through a specific port, are the highest-paid branch and also the hardest to enter. Most pilot groups take a small number of experienced masters through a multi-year apprenticeship.
Tuition, fees, exams and kit. Not rent, food or travel
There are two genuinely different routes. The low end is starting as a deckhand, earning while you build sea time, then paying for the required safety and licence courses yourself, several thousand dollars, plus the credential application, a medical and a drug test. That cheap door is slow and harder to walk through: it takes years of sea time and you have to chase the right billets to qualify. The high end is four years at a state maritime academy at in state rates, which gives you a bachelor's degree and the licence together. Union schools and many employers cover the course fees, which can pull the low end close to nothing.
If you take the academy route, file the FAFSA (Free Application for Federal Student Aid) first. Pell Grants and federal student loans apply to state maritime academies like any other public university.
Equal time rotations
Two weeks on and two weeks off, or 28 and 28, or 90 and 90 on deep-sea ships. Your days off are genuinely off.
Room and board included
You live on the vessel while you work, so your spending goes down while you are earning.
Overtime and penalty rates
Union contracts pay extra for cargo work, hazardous cargo and holidays.
Upgrades raise the rate
Every step up in license tonnage or rank moves your daily rate, so studying between trips pays directly.
The exact path from high school to qualified.
Two routes exist. One starts with a degree, the other starts with a mop and a mooring line.
High school diploma or equivalent
Grade 12
Math, physics and English. You also need to pass a medical exam and a drug test before you can hold a credential.
Pick your route
Decide at 18
A four-year maritime academy, which gives you a bachelor's degree and an officer license together, or entry-level work on deck, which gives you sea time and no debt.
Build documented sea time
2 to 4 years
Every license is measured in days actually served on a vessel. Academy cadets get theirs on training ships and commercial voyages. Deckhands get theirs by working.
Courses and the license exam
Months of classes
US Coast Guard approved training in navigation, stability, firefighting, lifeboats and radar, then the exam for your first officer license.
Upgrade as you go
10 years or more
Third mate to second to chief mate to master, each one more sea time plus more courses. Some mariners spend a whole career climbing it.
Math and trigonometry
Navigation is geometry on a sphere, and you still learn to do it without a screen.
Physics
Stability, buoyancy and how much a loaded ship will roll are physics problems with consequences.
English
Logs, radio calls and incident reports all have to be clear and exact.
Anything mechanical
Even a deck officer needs to understand what the engine room is telling them.
This is one of the few careers in the country with a single national license instead of fifty state ones. The Coast Guard issues the Merchant Mariner Credential, which records your officer rank, the size of vessel you may command and the waters you may work. It is backed by the international convention known as STCW (Standards of Training, Certification and Watchkeeping), so American officer training is recognized abroad. Every level requires documented days at sea, approved courses, a medical certificate and an exam, and the credential has to be renewed.
State maritime academies
Massachusetts Maritime Academy and SUNY (State University of New York) Maritime College are two of the six state academies, each a four-year college with a license program attached.
The federal academy at Kings Point, New York
The United States Merchant Marine Academy, a federal service academy with a service obligation after graduation.
Union and industry schools
MITAGS (the Maritime Institute of Technology and Graduate Studies) runs an apprenticeship that takes people from entry level to a mate's license in a little over two years.
Company training programs
Tug, ferry and offshore operators often pay for the courses that upgrade their own deckhands.
Things you don't need, but that help.
Tankerman
Required to handle liquid cargo. Tankers and fuel barges pay more, and this is why.
Towing endorsement
The separate credential for pushing and pulling barges. A whole industry on the inland rivers runs on it.
Radar observer and electronic charts
Standard for bridge watch, renewed regularly.
Unlimited tonnage
The difference between running a harbor tug and sailing as an officer on an ocean-going ship.
A stomach for being away
Weeks or months at a time, missing birthdays and holidays. Test it on a short contract before you commit.
Clean medical and drug record
The credential depends on both, and random testing is part of the industry.
Basic mechanical and electrical skill
On a small vessel the mate fixes things. There is nobody else.
Patience with paperwork
Logs, checklists, inspections and port documents take up a real share of a modern officer's day.
Most American mariners never cross an ocean. They work harbor tugs, river tows on the Mississippi and Ohio, passenger ferries, crew boats servicing offshore platforms, research vessels, dredges and fishing boats. Those jobs come with shorter rotations, sometimes even a daily commute home, and they are where most first officer licenses get used. Deep-sea work pays more and takes you further from home for longer.
Day to day, pros and cons, where you'd work.
Officers stand watches, usually four hours on and eight off, around the clock. On watch you are responsible for the vessel: plotting the passage, watching radar and traffic, giving helm and engine orders, talking to other vessels and to port control. Off watch you sleep, eat and do paperwork, then get up and do it again at 4am. In port the pace flips to cargo operations, inspections and safety drills, and nobody gets a normal night.
The good
The hard parts
Things people don't tell you.
Every step up the ladder is measured in documented days actually served on a vessel. A day ashore does not count. Mariners keep a sea service record the way other trades keep apprenticeship hours, and losing it is a real problem.
When a large ship enters a port, a harbor pilot boards from a small boat and takes over the navigation. They know that one stretch of water better than anyone on board. It is among the best-paid maritime jobs in the country and takes years of apprenticeship to enter.
Towboats push strings of barges thousands of miles along the Mississippi and its tributaries carrying grain, coal and fuel. It is an entire maritime industry with its own licenses, its own crews and no ocean anywhere in it.
Almost every regulated job on this site is licensed state by state. Ship officers are the opposite: the US Coast Guard issues one credential that works in every state and on every American flag vessel.
Last checked September 2026. Pay figures are typical full-time annual amounts in United States dollars, based on Bureau of Labor Statistics wage data and published pay scales. They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise.
