The honest answer to what an able seaman earns is that it depends significantly on vessel type, flag state, operator and your country of origin. The range is wide enough that two ABs with identical certificates can be earning very different amounts on vessels that pass each other in the same shipping lane.
Here are the numbers with the context that makes them meaningful.
How AB Wages Work
AB wages are monthly contract rates paid during time on board. Leave periods are unpaid for most seafarers. The monthly figure needs to be adjusted for the unpaid leave before it can be meaningfully compared to a shore-based salary.
On a four months on, two months off rotation, the AB works eight months of the year. Annual income is the monthly rate multiplied by eight, not twelve. This calculation surprises some people who focus on the monthly number.
By Vessel Type
Crude and product tankers pay the highest AB wages across merchant shipping sectors. The combination of cargo complexity, safety requirements and the additional tanker endorsements required justifies a premium.
Crude tanker AB monthly rate: $1,600 to $2,500 Product tanker AB monthly rate: $1,500 to $2,400 Chemical tanker AB monthly rate: $1,700 to $2,600 LNG carrier AB monthly rate: $1,900 to $2,800
Bulk carriers and general cargo vessels pay less. The work is less technically demanding and the supply of available ABs for these vessel types is larger.
Bulk carrier AB monthly rate: $1,200 to $1,900 General cargo AB monthly rate: $1,100 to $1,800
Container ships pay in a similar range to tankers at some operators and closer to bulk carrier rates at others depending on the company.
Container ship AB monthly rate: $1,400 to $2,200
Cruise ships are a different market. The base AB wage on a cruise ship is often lower than on cargo vessels but total earnings including overtime can be comparable or higher depending on the vessel and operator.
Cruise ship AB monthly base: $1,100 to $1,800
Offshore supply vessels have their own pay structure. The rotation is shorter, often two to four weeks on and equivalent leave, and the monthly rates reflect this.
Offshore AB monthly rate: $2,500 to $4,000 for North Sea operations, lower for other regions.
Nationality and Flag State
This is uncomfortable to discuss plainly but it is real. Some flag states operate different wage scales for different nationalities. A Filipino AB and a European AB on the same vessel with the same certificates can earn significantly different amounts under some operators and flag states.
The ITF, which represents seafarers internationally, sets minimum wage recommendations that apply to ITF-affiliated operators. ITF minimum for an AB was around $1,800 per month at last review, applied to the basic wage before overtime. Operators outside ITF collective bargaining agreements may pay less.
Knowing whether a vessel and operator are covered by an ITF CBA is worth checking before accepting a contract.
Overtime
Most AB contracts include a guaranteed overtime component above the basic wage. Overtime rates vary by contract but typically add twenty to forty percent to the basic monthly figure. A basic wage of $1,600 with standard overtime often produces total earnings of $2,000 to $2,200 per month.
Read the overtime terms in any contract before signing. Some contracts guarantee a fixed overtime amount regardless of hours worked. Others pay actual overtime on top of basic. The difference matters for budgeting.
What Moves the Number Up
Tanker endorsements add value. An AB with basic oil tanker training endorsed on their STCW certificate earns more than an equivalent AB without it.
Pump man qualification adds a meaningful premium for ABs on tankers. The pump man is responsible for the pump room and cargo pumping systems and the specialised knowledge this requires is compensated.
Bosun experience, even without the formal bosun rating, shows in the wage offers from operators who value demonstrated leadership of the deck crew.
Time with one operator builds salary in a way that jumping between operators does not always match. Operators who value retention offer incremental increases to returning crew members.
