CrewChangeDeckhand to Wheelhouse
Every pilot on the river started on deck. The ladder from throwing rigging to standing a wheel watch is written in federal regulation — 540 days of sea time, a five-module exam, and a skills book called the TOAR — and a hand who works it steadily can go from green deckhand to the sticks in 3 to 5 years, earning the whole way up. Here’s the ladder, rung by rung, from a captain who climbed it.
How the towing license ladder actually works
There are three rungs above the deck: Apprentice Mate (Steersman) — the learner’s permit that lets you steer under a licensed officer’s watch; Mate (Pilot) of Towing Vessels — a full wheelhouse officer standing their own watch; and Master of Towing — the captain. Each rung is earned with documented sea time plus a gate: an exam for steersman, the TOAR for mate, more time for master.
Everything runs on paper you control: your MMC and a folder of sea service letters. Start both your first year on deck — the hands who stall on the ladder are almost never short on ability, they’re short on documentation.
The sea time you need — and the rule that speeds it up
To sit for the steersman exam you need 540 days of sea service, of which 360 days on towing vessels and 90 days on the route you’re applying for (Western Rivers, for most of us). Any position counts toward the total — your deckhand time is ladder time.
The accelerator most green hands don’t know: on a two-watch towboat working 12-hour days, every day aboard counts as a day and a half of sea service. Work even time (28/28 or 20/20) and you bank roughly 270 credited days per calendar year — which is how 540 days comes down to about two calendar years minimum, realistically two to four. A Coast Guard–approved steersman course can knock off more.
The steersman exam, module by module
The Western Rivers exam is five modules. Four of them pass at 70%. One doesn’t — and it’s the one that sends people home:
| Module | Questions | To pass |
|---|---|---|
| Rules of the Road: Inland | 50 | 90% |
| Deck General | 50 | 70% |
| Deck Safety | 50 | 70% |
| Navigation General: Western Rivers | 50 | 70% |
| Navigation Problems: Chart Plot | 10 | 90% |
Rules at 90% means you get five questions wrong out of fifty — total. That’s not a cram-the-night-before module; it’s months of steady drilling. Our free Rules of the Road practice test works exactly that muscle — 20 random Inland questions a sitting, graded against the same 90% bar, with the rule behind every answer. (The Great Lakes/Inland route swaps in different module numbers and the combined International-Inland rules exam; going to oceans later means a fresh ocean exam.)
Requirements to sit: 18 or older, the sea time above with 90 days in the last three years, a valid TWIC, medical certificate, first-aid/CPR, and a current drug test. Coast Guard fees: $240 ($100 evaluation + $95 exam + $45 issuance) on pay.gov.
After the license: steering time and the TOAR
The steersman license is a learner’s permit — you steer under the watch of a licensed mate or master. Two things happen during that stretch:
You build steering time. Mate (Pilot) of Towing takes 30 months of total service including 12 months as steersman, plus your route time.
You complete the TOAR — the Towing Officer Assessment Record, a practical checklist of real wheelhouse skills (flanking, landings, locks, tow work) signed off item by item by a Designated Examiner: an experienced towing officer the Coast Guard has approved to witness and certify each skill personally. No TOAR, no mate’s license — so find out early which officers in your fleet are DEs, and steer for them every chance you get.
One route gotcha worth knowing: even a licensed mate needs 90 days of observation on the Western Rivers before standing a wheel watch there if the route isn’t already on the license. And past mate, the ladder keeps going: Master of Towing at 48 months total, including 18 as mate.
What it costs and how long it really takes
| Item | Cost |
|---|---|
| TWIC card | $124 |
| Entry MMC (fees) | $140 |
| Steersman application + exam + issuance | $240 |
| Physical & drug test (each round) | ~$150–250 |
| Hard costs, self-study | ~$650–750 |
| Approved steersman prep course (optional) | ~$1,000–3,500 |
Timeline, honestly told: about 2 years minimum of even-time decking to reach the exam, then 12+ months steering while the TOAR fills in — call it 3 to 5 years from green hand to mate (pilot). Compare that to any path from $40k to six figures that pays you every rung of the way, and the wheelhouse math holds up fine. What a pilot actually earns is on the wheelman pay page.
The ladder starts with a deck job
Sea time only counts once you’re aboard. One free application, built by a working captain, puts you in front of the inland companies hiring right now — green hands included.
Start my application →Wheelhouse questions, answered straight
How long from deckhand to pilot?
Realistically 3–5 years: about 2 years of even-time decking to earn the 540 days, the exam, then a year or more steering while you complete the TOAR.
What’s the hardest part of the exam?
Rules of the Road at 90% — five wrong answers allowed out of fifty. Everything else passes at 70%. Drill the Rules for months, not weeks; the free practice test uses the same 90% bar.
Do I need to go to a school?
No — self-study is legal and plenty of pilots did it that way. Approved courses ($1,000–3,500) can reduce your required sea time and structure the studying; whether that trade is worth it depends on your discipline and your company’s tuition help. Ask — many towing companies pay for steersman school.
Who signs my TOAR?
A Designated Examiner — a towing officer the Coast Guard has approved to assess skills. They must personally watch you perform each item. Find your fleet’s DEs early and steer for them.
Does deckhand time on any boat count?
Your 540-day total can come from any position, but 360 days must be on towing vessels and 90 on your route. Inland towboat time on two-watch boats earns the 1.5x day credit — documented by sea service letters, so collect them from hitch one.
