Knowledge test for deck officers
For masters and mates the recruitment knowledge test goes deep: COLREG and watchkeeping, passage planning and position, radar and ARPA, cargo work and stability, emergencies, pollution and the conventions. Senior ranks get more questions on leadership, security and law.
Sit the practice test for deck officers
If you are a Master, Chief Officer, Second or Third Officer, or a deck cadet about to sit for a first officer job, this is your paper: 30 multiple-choice questions drawn from 513 original questions relevant to your rank, 30 minutes, no feedback until the end, then a score by knowledge area with links to revise. All questions are ours; nothing comes from any real test.

What the test covers for deck officers
Weighted by the competence tables of STCW A-II/1 and A-II/2. "Core" areas give most of the questions; "basics" appear once or twice.
| Knowledge area | Weight | Share | Revise |
|---|---|---|---|
| Cargo work | core | 6% | |
| Communications, SMCP and GMDSS | core | 6% | VHF and Channel 16 |
| Conventions and regulations | core | 6% | STCW English requirements guide |
| Emergencies, fire and life-saving | core | 6% | Life-saving appliances and fire protection |
| Leadership, teamwork and fatigue | core | 6% | |
| Occupational safety and permits | core | 6% | Ship safety signs |
| Passage planning and position | core | 6% | Units and coordinates |
| Pollution prevention (MARPOL) | core | 6% | |
| Radar, ARPA and ECDIS | core | 6% | |
| Ship handling, mooring and anchoring | core | 6% | SMCP wheel and engine orders |
| Ship security (ISPS) | core | 6% | |
| Stability and seaworthiness | core | 6% | |
| Vessel types and their cargoes | core | 6% | English and safety by ship type |
| Watchkeeping and COLREG | core | 6% | COLREG lights, rules and sound signals |
| Deck work and equipment | important | 4% | |
| Meteorology | important | 4% | Beaufort scale |
| MLC: rest hours, contracts and welfare | important | 4% | |
| Fuel, lubrication, ballast and pumps | basics | 2% | |
| Galley, food hygiene and catering | basics | 2% | Fire protection (galley fires) |
| Maintenance, tools and repair | basics | 2% |
Most lost points are in the rules everybody "knows": COLREG lights and give-way situations, MARPOL discharge criteria, rest hours. Revise them from the text, not from memory.
Sample questions for deck officers
Five questions of the kind you will meet, from the core areas. Think first, then open the answer.
-
Passage planning and position What are the four stages of passage planning?
- Appraisal, planning, execution, monitoring
- Departure, sea passage, arrival, berthing
- Chart work, weather, tides, fuel
- Briefing, watch, log, report
Show the answer
Appraisal, planning, execution, monitoring. IMO resolution A.893(21), Guidelines for voyage planning: appraisal, planning, execution and monitoring.
-
Vessel types and their cargoes On a bulk carrier, the main danger of loading a heavy cargo like iron ore too fast is:
- Making the ship too light
- Damaging the cranes
- Wetting the cargo
- Overstressing the hull structure
Show the answer
Overstressing the hull structure. Loading sequences must follow the loading manual; the BLU Code covers safe loading and unloading of bulk carriers.
-
Ship handling, mooring and anchoring In a narrow channel close to a bank, bank effect tends to:
- Have no effect
- Stop the ship
- Push the bow away from the bank and suck the stern towards it
- Pull the bow into the bank
Show the answer
Push the bow away from the bank and suck the stern towards it. The result is a sheer away from the bank; counter it early with rudder and keep to the centre where possible.
-
Emergencies, fire and life-saving How does a fire damper differ from a smoke damper?
- They are two names for the same device
- The fire damper maintains the fire resistance of the division; the smoke damper only limits the flow of smoke and hot gases
- The smoke damper maintains the fire resistance and the fire damper only stops smoke
- The fire damper is closed by hand and the smoke damper works by itself
Show the answer
The fire damper maintains the fire resistance of the division; the smoke damper only limits the flow of smoke and hot gases. See the card: Fire doors and fire dampers. Read more
-
Vessel types and their cargoes Topside and hopper tanks on a bulk carrier:
- Are the sloping tanks in the corners of the holds that self-trim the cargo and carry ballast
- Are the fuel tanks
- Are the slop tanks
- Are the lifeboat stations
Show the answer
Are the sloping tanks in the corners of the holds that self-trim the cargo and carry ballast. The hold shape lets the cargo settle without manual trimming for most cargoes. Read more
How to prepare
- Revise the core areas first. Cargo work, Communications, SMCP and GMDSS, Conventions and regulations, Emergencies, fire and life-saving, Leadership, teamwork and fatigue, Occupational safety and permits, Passage planning and position, Pollution prevention (MARPOL), Radar, ARPA and ECDIS, Ship handling, mooring and anchoring, Ship security (ISPS), Stability and seaworthiness, Vessel types and their cargoes, Watchkeeping and COLREG.
- Sit the test more than once. Every sitting draws a new set; the areas that stay red are the ones to study.
- Do the English test too. Many employers require both an English score and a knowledge score: full practice test with listening, or the 20-question English check.
- Going to sea? Save the tests on your phone and practise without a connection.
