In the oral, command means the examiner stops testing your seamanship and starts testing your judgement. Every scenario answer needs the same four legs under it — the ship, the people, the law, and the money — and it needs to hold when the examiner pushes back.
A chief mate answering an oral question stops as soon as the ship is safe: the leak is contained, the boat is recovered, the fire is out. That answer is correct as far as it goes, and it is also incomplete for a master's ticket. The examiner already knows you can make a situation safe — that was tested at the last certificate. What's being tested now is what a master does once the immediate danger has passed, because that is the part a chief mate is never asked to do.
Structure every scenario answer across four domains, in the same order, whether or not the examiner prompts you: the ship (what's actually wrong, and is it still seaworthy), the people (informed, safe, looked after — including families, if it's come to that), the law (who has to be told — flag, class, the coastal state, the company's DPA — and roughly how urgently), and the commercial consequence (schedule, cargo, cost, the charterer). Close with the part candidates forget: what you would change so it doesn't happen again. An answer that stops at "safe" and never reaches "and here's what I'd change" reads as competent but junior.
A command-level answer is not a better version of a chief mate's answer — it covers ground a chief mate's answer never touches. Practise adding that last sentence, not just getting to "safe".
"How would you satisfy yourself the ship is ready to sail?" is really asking whether you know what a handover consists of, because that is the only moment you fully control it. Once you've signed for command, any gap you didn't find becomes yours. Work through it as a fixed list, delivered calmly and in order — examiners mark the structure as much as the content.
Deliver that list unprompted and the examiner has less to probe for — you've shown you know what "fit to sail" is actually built from, rather than promising to "check everything", which tells them nothing.
The scenario is usually specific: a serious injury, a major fire, flooding, or a collision, days from the nearest port with meaningful medical or repair support. The examiner isn't testing whether you know the emergency procedure — you do. They're testing what you do once the checklist runs out and the next move is a judgement call with real trade-offs on both sides.
Make it safe first — stabilise the casualty, contain the fire or flooding, muster and account for everyone before anything else. Then assess honestly: the injury's true severity, the extent of damage, what the ship can still do and what it can't. Inform next — the company, the flag state if the incident meets their reporting threshold, and the nearest rescue co-ordination centre if you need assistance or advice, even before you're sure you need a full rescue. Plan the next move with that information: continue, divert, request a medevac, or heave to and wait for better conditions — and be ready to explain why that option beats the alternatives, not just that you chose it. Record throughout, not afterwards: log entries with times, photographs where it's safe to take them, and statements taken while memories are fresh, because that record is what class, flag, the P&I club and any later inquiry will all rely on.
Being "far from help" is the part candidates under-answer. It means you own the decision for longer than usual, with less outside advice to lean on — say that explicitly, rather than describing the procedure as though a rescue co-ordination centre is always five minutes away.
Two different scenarios, but the same instinct is being tested: do you treat the examiner's phrase as a decision to work through, or as a soundbite? First: a port state inspection is heading toward detention. The deficiency itself is rarely the interesting part of the answer — what's tested is what you do about it. Understand precisely what's been found and why it matters, not just that an inspector wrote it down. Agree corrective action with the class surveyor or flag, in writing, rather than fixing it and hoping it's accepted. Gather evidence as you go — photographs, test results, spares fitted — and close the deficiency out formally, because an inspector re-checks against the record, not against your assurance that it's sorted.
Second: a crew fatality on board. The sequence examiners look for is: preserve the scene exactly as it is, because it may be examined by the flag state or local authorities; notify the flag and the company immediately, before anything else moves; and never contact next of kin directly — that goes through the company, who are trained for it and who the family will need to deal with afterwards regardless. Coordinate with the local authorities or coroner on the practical questions — repatriation, evidence, statements — and keep your own account factual: what was found and when, not a theory about cause offered before there's evidence for one.
Both scenarios reward the same discipline: preserve the evidence, follow the reporting chain, and don't let the first plausible explanation into the record before it's actually established.
When the scenario is a charterer's instruction you consider unsafe, the examiner is checking whether you know the master's overriding authority is a defined right, not something you're inventing on the spot to sound cautious. It exists specifically for this: a commercially convenient instruction that compromises safety, security or the environment. The standard is not "comply and hope it's fine" or "comply under protest" — it's refuse, and act.
Explain the reason, propose the alternative, inform the company and the DPA, and record it. That sequence is the whole answer — deliver all four, not just "I'd refuse".
The second half of this topic is "satisfy yourself" questions — how do you know the lifeboat davits are safe, that the cargo is properly secured, that the crew is fit for the passage. The weak answer is "I would check it", which names no standard and tells the examiner nothing about what you'd actually find. The strong answer always has four parts: the test you'd apply, the record that shows it was done, the tolerance or standard it's measured against, and who verified it. That structure works for almost any "how would you know" question this paper can ask.
Both threads meet at the same failure mode: folding under pressure. An examiner who pushes back on a correct answer is testing whether you hold it or change it to please them. Change an answer only when new information genuinely changes the analysis — never because the questioning got harder.
Both examples below are judgement walkthroughs, not calculations — the numbers only matter for deciding whether the ship, the certificate, or the schedule is actually the problem. Talk through the reasoning the way you'd have to in the room, not just the final decision.
You join the vessel in port as relief master, sailing in 18 hours on an 11-day laden passage with no intermediate port calls. The outgoing master's handover pack is on the table. What do you check, and are you satisfied the ship is fit to sail?
Departure in 18 hours; passage is 11 days with no intermediate port Outstanding condition of class on the emergency generator, logged 9 days ago, no completion evidence on file Chief mate's certificate of competency endorsement expires in 6 days Bosun's rest-hour record for the last 7 days totals 70 hours, split across more than two rest periods on 2 of the days Departure stability condition: GM 1.8 m, within the approved range on the loading computer printout Last lifeboat lowering drill recorded 18 days ago
What do you check, and are you satisfied the ship is fit to sail?
Triage first.
Two items in the pack check out and three don't — sort them before reacting to any one line. The stability condition (GM 1.8 m, within the approved range) and the boat drill (18 days ago, inside the 30-day requirement) need no action. The generator's condition of class, the mate's certificate, and the rest-hour record are all still open.
The condition of class needs a status check, not a guess.
An open condition with no completion evidence on file isn't automatically a bar to sailing — some are running against an agreed rectification period with class. But treating it as fine without confirming that is worse than asking.
The mate's certificate is the harder stop.
Work out how much of the passage it actually covers, not just how many days remain today.
The rest-hour record fails on two counts, not one.
The total and how it was split.
Weigh the three open items together against the 18-hour departure window.
Rather than deciding each one in isolation.
AnswerNot fit to sail as found. Confirm the generator condition's status with class before treating it as closed; renew, extend, or relieve the chief mate's certificate so no part of the passage is sailed unendorsed; and correct the bosun's rest-hour deficit — reschedule to recover the missing hours and bring the rest periods back to two — before signing to depart, even if that pushes departure back a few hours.
The trap: announcing the ship "fit to sail" after checking only the items that were already in order, instead of working through the whole handover pack and closing out each one that wasn't.
Your vessel is on a laden passage under the charterer's voyage orders, instructing the direct great-circle route to meet the charterparty's laycan. Your own weather routing shows a low-pressure system putting a significant wave height of 7 m on the beam across your track in 36 hours — above your vessel's heavy-weather guidance for this loaded condition. The charterer has asked you to confirm the direct route will be followed.
Direct route: meets the laycan with 1 day of margin Forecast significant wave height on the direct route: 7 m on the beam in 36 hours, confirmed by two independent routing services Vessel's own heavy-weather routing guidance for this loaded condition: avoid beam seas above 5 m Weather-avoidance route: 1.5 days longer transit The charterparty contains a routing/speed clause the charterer is citing
Compare the forecast against the vessel's own limit before anything else.
This is a safety threshold you've already set for this loading condition, not a matter of preference on the day.
The charterparty's routing clause does not reach this far.
A speed or routing instruction is a commercial term; it doesn't override the master's responsibility for the safety of the ship, crew, and cargo. Confirming the direct route here would be doing exactly that.
Work out what the alternative actually costs before proposing it.
A vague "a bit longer" isn't a proposal an office can act on.
Inform before executing.
Not after: the company and the DPA need the forecast and the reasoning while there's still time to manage the laycan commercially, and the log needs the same information recorded as it stood at the time of the decision.
Hold the position if the charterer pushes back citing the clause.
The safety decision doesn't move — only who deals with the commercial fallout is open for discussion.
AnswerDecline the direct route and take the weather-avoidance routing, missing the laycan by roughly half a day. Inform the company and DPA before executing the deviation, log the forecast and the vessel's own heavy-weather limit as the basis for the decision, and leave the laycan consequence for the company to resolve commercially with the charterer — it is not a reason to sail through conditions 2 m over the ship's own guidance.
The trap: offering to "monitor and decide closer to the time" instead of committing to the deviation now — to an examiner that reads as leaving the door open to the commercially convenient answer once the pressure is back on.
