How to Become a Towboat Deckhand
To become a towboat deckhand you need three things: a TWIC card ($124, allow up to 60 days), a passed physical with drug screen, and a completed application in front of companies that hire green hands. No maritime school, no license, and no experience required — inland companies train you aboard and pay $160–$210 a day while they do it.
Written by a working inland captain. This is the same path our own crews came up on.
The five steps, in order
- Get your TWIC card — start this today
The TWIC (Transportation Worker Identification Credential) is a federal ID card for transportation workers. Apply online at tsa.gov/twic, then visit an enrollment center with your driver’s license and birth certificate or passport. Cost: $124 — TSA lowered it in 2025, so ignore any site still quoting $125.25. Valid: 5 years. Lead time: 2–8 weeks — which is why it’s step one. Full walkthrough, including waivers if you have a record: the TWIC card guide. Most companies will start your paperwork with the enrollment receipt in hand.
- Be ready for the physical and drug screen
Companies send you for their own physical and a DOT drug test during hiring — you don’t arrange these yourself, and it’s not a USCG medical card (you don’t need one to deck). You’ll need to lift 75 lbs, climb ladders, and work outdoors around moving wire. Get clean and stay clean: random testing continues on the job.
- Skip what you don’t need yet
You do not need an MMC (Merchant Mariner Credential), a USCG medical card, a captain’s license, or maritime school to deck on an inland towboat. The MMC matters later — when you go for tankerman or the wheelhouse. Don’t let anyone sell you a course to carry lines.
- Complete your application — all of it
Hiring companies only get shown completed profiles. Fill out the CrewChange application in one sitting (it saves as you go): your TWIC status, the rotations you’ll work, when you can start, and check your skills honestly — “no experience” is an honest answer we built a checkbox for.
- Take the call and catch your boat
When a company wants you, they call you directly. Say yes, get your travel details to the crew change point, and pack light: work clothes, steel-toe boots, rain gear, and twice the socks you think you need.
What it costs and how long it takes
| Item | Cost | Time |
|---|---|---|
| TWIC card | $124 | 2–8 weeks |
| Physical + drug screen | usually company-paid | 1 day |
| CrewChange application | free | ~15 minutes |
| Steel-toe boots & gear | $150–$250 | — |
| Total out of pocket | under $400 | TWIC is the clock |
Compare that to any trade: no other path puts you at $40,000+ your first year for under $400 up front. And there are two sides of the deck — liquid tank barges and dry line-haul — that pay differently down the road; the deckhand pay page breaks down both.
What your first hitch is actually like
You’ll live aboard for your rotation — 28 days on and 14 home is common for green hands — standing watch six hours on, six off. The work: building and breaking tow (laying rigging, throwing ratchets and wire), handling lines through locks, chipping, painting, and keeping the boat up. Meals and a bunk are covered; there’s no rent, no commute, and no spending your check until you’re home.
Want a head start on the deck work itself? Run the free barge mooring trainer — it teaches forward leads, backing leads, and breasts before you ever step on steel.
Ready to get on a boat?
One application, built by a real working captain — not a bot. Complete it and you go straight in front of hiring companies on the deck. No fees, no recruiters, no runaround.

How old do I have to be?
18. There’s no upper limit that matters — companies hire green hands in their 40s and 50s who can pass the physical.
Can I get hired with a record?
Often, yes. TWIC has its own federal disqualifier list, and each company sets its own policy. Be straight about it on your application — our disclosure field goes only to employers you move forward with.
Do towboat deckhands need an MMC?
Not to start on inland boats — a TWIC is enough. You’ll want one later for tankerman work or the wheelhouse path — and by then you’ll have sea time that counts toward it. Full breakdown: the MMC guide.
What rotation should I ask for?
Take what gets you aboard — usually 28/14 for green hands. Once you’ve proven up, you’ll have your pick. Punch rotations into the day rate calculator to compare what they pay.
