The question comes up constantly and the honest answer is more nuanced than a simple yes or no.
What No Prior Experience Actually Means
If it means no sea time and no maritime certificates, you cannot start as an AB. The AB rating requires documented sea service and specific STCW certificates. These cannot be waived.
If it means no professional sea experience but you are willing to start at a lower rating and build toward AB, that route exists and people take it regularly.
The starting point for most people entering the industry without prior sea time is ordinary seaman or deck hand. These positions require basic safety training and a maritime medical certificate but do not require the AB certificate or prior sea service.
What You Do Need Before Any Sea Job
STCW Basic Safety Training. Four courses, approximately one week, available at maritime training centres in most countries. This is the minimum threshold for commercial maritime employment. There is no going around it.
Maritime medical certificate. Standard seafarer medical examination by an approved doctor. Most healthy adults pass without difficulty.
These two things together are achievable in two to four weeks and are the foundation that all subsequent maritime employment builds on.
The Ordinary Seaman Route
OS positions are the legitimate entry point for people without sea experience. The work is deck labour: maintenance, watchkeeping assistance, mooring assistance under the supervision of experienced crew. The pay is lower than AB rates.
Sea service accumulated as an OS counts toward the eighteen months required for the AB certificate. After eighteen months of documented sea service plus the required additional training, the AB certificate application goes to the flag state administration.
The OS to AB progression is the standard pathway in the industry. Most people currently working as ABs started as ordinary seamen.
What Actually Helps
Practical skills that translate. Experience with ropes, machinery, engines, boat handling: all of these are noticed positively even if they come from recreational sailing, fishing, or any trade involving physical mechanical work.
Physical fitness. The job is physically demanding. Applications from people who are clearly capable of the physical requirements of deck work are taken more seriously.
Strong STCW training results. Some maritime training centres offer extended programmes beyond basic safety training that cover seamanship foundations. Completing one of these before applying impro
