Pass the USCG Able Seaman (AB) written exam on the first try. Adaptive practice for both written modules — Navigation & Rules of the Road and Deck General & Safety — with every question grounded in the USCG Navigation Rules, 46 CFR, and NOAA Coast Pilot. (Covers the written exam only; the practical knots/lifeboat demonstration is administered separately.)
This is the whole difference. Get one wrong and you won't just see the answer — you'll meet the tutor.

Every question targets the topic where you're weakest — weighted by blueprint share, your ability, and recency. The hours you put in actually move the needle.
Wrong answers summon a coach that asks "what made you pick B?" and walks you to the reasoning over a few turns — not a one-line answer key you forget by the next question.
Talk through the operational parts of AB Seaman prep out loud — the kind no flashcard app can simulate. Builds the recall you need when the test isn't multiple choice.
Sourced from primary federal regulations and study guides — re-ingested on a schedule, never loosely paraphrased.
The Able Seaman (AB) rating is the highest-volume deck credential the U.S. Coast Guard issues. It’s the step up from Ordinary Seaman that qualifies you for the full range of deck work aboard commercial vessels — watchkeeping, lookout, helm, cargo handling, and lifeboat duties.
The USCG National Maritime Center administers the AB written exam in two modules:
Note: This product preps the written exam only. The practical demonstration — tying knots and handling a lifeboat in front of an examiner — is administered separately by the USCG. We get you through the written; you’ll do the hands-on practical at your school or REC.
The Navigation & Rules of the Road module is unforgiving: it’s a long list of exact light configurations, signal patterns, and right-of-way decisions, and the exam expects them cold. Candidates who “kind of know” the difference between give-way and stand-on, or who blank on what two vertical red lights mean, are the ones who retest. That’s exactly the material adaptive drilling fixes fastest.
Built for deckhands earning their first deck rating. Same engine that powers our OUPV and 100-Ton Master products — the AB content is independently sourced from the federal rules, so your practice rate isn’t capped by what you’ve seen elsewhere.
Every other AB Seaman app is the same rectangle of question, four buttons, one big "Next." It works — and it's genuinely uninspiring.

No app can guarantee a pass — anyone who promises that is lying to you. What we can do is target your weak topics, teach the reasoning behind every miss, and give you an honest readiness signal before you sit the exam. Most candidates who reach "ready" on our diagnostic pass on the first try.
Yes. Questions are generated and checked against the current AB Seaman source documents, then re-ingested on a schedule when those documents change. We don't ship loosely paraphrased material.
If PassFirst isn't right for you, email us within 14 days for a full refund — no rage-bait "are you sure?" flow, no hoops. We'd rather you trust us than feel trapped.
The question pool tracks the current federal source documents. When the regulations update, the affected questions are regenerated and re-verified — and your access carries through it.
This is a federal credential, so the question pool is scoped to exactly the federal knowledge sections you'll be tested on — no state variations to worry about.
