DG Exit Exam
Answer Key

GSK exit exam questions and answers — Set 16 — General Ship Knowledge

Set 16 of the General Ship Knowledge (GSK) exit exam bank — 30 of 585 questions, with the correct option marked and a one-line explanation for every one. Read it end to end, jump to a single set, or search it — then sit the same bank as a timed paper. The real DG Shipping exit exam is 30 marks with 15 to pass.

These are the bank's original groupings. Practising deals the whole bank out again every time you reshuffle, so a practice “Set 3” is a different 30 questions each time — the set numbers below are the source file's, and are only used here so the key stays navigable. Options are listed in their original order with fixed letters; when you practise, those move too.

  • A. The ship's agent at each port
  • B. The port health officer only
  • C. The master or an officer designated by the master
  • D. The chief cook alone, without records
Answer: C — The master or an officer designated by the master
MLC 2006 Standard A3.2 requires frequent documented inspections of food and drinking water supplies, storage and handling spaces and galley equipment by, or under the authority of, the master, with the results recorded.

3. If a rating witnesses sexual harassment of a crew member on board, the correct action is to

  • A. Keeping safety shoes on the dining table
  • B. Leaving used plates on the table for others to clear
  • C. Changing out of dirty working clothes before entering the mess room for meals

  • A. Drinking only bottled water
  • B. Washing hands frequently
  • C. Avoiding contact with stray dogs
  • D. Taking prescribed anti-malarial medicine and avoiding mosquito bites with nets, repellents and covering clothing

  • A. Avoiding drinking water until the work is finished
  • B. Drinking water regularly and taking rest breaks in a cool place
  • C. Working faster to finish the job quickly
  • D. Drinking alcohol after the work to cool down
Answer: B — Drinking water regularly and taking rest breaks in a cool place
In hot conditions the body loses large amounts of water and salt through sweat. Regular drinking of water and breaks in a cool area prevent dehydration and heat exhaustion; alcohol increases dehydration.

  • A. Wear the same socks for several days
  • B. Walk barefoot in shower rooms
  • C. Keep the feet clean and dry and change socks daily
  • D. Keep wet safety shoes on after work
Answer: C — Keep the feet clean and dry and change socks daily
Fungal infections grow in warm, damp conditions. Washing and drying the feet well, especially between the toes, and wearing clean dry socks every day are basic personal hygiene habits that prevent it.

8. Under STCW, the maximum blood alcohol content permitted for a seafarer performing designated safety, security and marine environmental duties is

  • A. 0.08%
  • B. 0.50%
  • C. 0.10%

  • A. QUESTION
  • B. INTENTION
  • C. ADVICE
  • D. REQUEST
Answer: B — INTENTION
The SMCP message marker INTENTION is used to inform others about immediate navigational actions intended to be taken by the sender, for example 'INTENTION. I will reduce my speed.'

10. Which SMCP message marker is used to inform others about a danger?

  • A. INTENTION
  • B. INFORMATION
  • C. ANSWER
  • D. WARNING
Answer: D — WARNING
The marker WARNING indicates that the message informs other traffic participants about dangers, for example 'WARNING. Obstruction in the fairway.' It tells the listener that the information concerns safety.

11. In the SMCP, the message marker INFORMATION is used for messages that are

  • A. Questions about the intentions of another ship
  • B. Requests for assistance
  • C. Restricted to observed facts, situations and the like
  • D. Orders the receiver must obey
Answer: C — Restricted to observed facts, situations and the like
According to the IMO SMCP, INFORMATION indicates that the following message is restricted to observed facts, situations etc., for example 'INFORMATION. MV Noname is overtaking you on your starboard side.'

12. Which SMCP message marker indicates that the sender wishes to persuade the recipient to take an action, but the decision remains with the recipient?

  • A. INSTRUCTION
  • B. ANSWER
  • C. ADVICE
  • D. WARNING
Answer: C — ADVICE
ADVICE implies the intention of the sender to influence the recipient by a recommendation; the recipient need not follow it. INSTRUCTION, in contrast, is used when the sender, such as a VTS station, has the authority to require the action.

13. An SMCP message preceded by the marker INSTRUCTION, for example from a VTS station, means that

  • A. The recipient may ignore the message
  • B. The message is for information only
  • C. The sender is only asking a question
  • D. The sender has the authority to make the recipient carry out the action
Answer: D — The sender has the authority to make the recipient carry out the action
The SMCP marker INSTRUCTION indicates that the sender, for example a VTS station or naval vessel, intends to make the recipient do something based on regulations or authority. It is therefore stronger than ADVICE.

14. The spoken signal used on VHF to indicate an urgency message, such as a man overboard or medical assistance, is

  • A. PAN-PAN, spoken three times
  • B. MAYDAY, spoken three times
  • C. SECURITE, spoken three times
  • D. SEELONCE, spoken three times
Answer: A — PAN-PAN, spoken three times
PAN-PAN repeated three times is the urgency signal, used when the safety of a ship or person is at risk but there is no grave and imminent danger. MAYDAY is for distress and SECURITE for safety messages.

15. The spoken signal SECURITE, repeated three times at the beginning of a VHF message, indicates

  • A. A safety message, such as a navigational or weather warning
  • B. The end of a communication
  • C. A distress message
  • D. An urgency message
Answer: A — A safety message, such as a navigational or weather warning
SECURITE (pronounced say-cure-e-tay) announces a safety message, for example an important navigational or meteorological warning. Distress uses MAYDAY and urgency uses PAN-PAN.

16. If a mistake is made while transmitting a message, the SMCP procedure is to say

  • A. "Out" and repeat the whole call later
  • B. "Mistake" followed by "Correction" and then the correct version
  • C. "Sorry" and start a new message on another channel
  • D. "Over" and wait for the other station
Answer: B — "Mistake" followed by "Correction" and then the correct version
The SMCP procedure for errors is to say 'Mistake', followed by the word 'Correction' plus the corrected part of the message, for example 'My present speed is 14 knots - mistake. Correction, my present speed is 12 knots.'

17. When radio procedure and the SMCP are used, the figure 9 is spoken as

  • A. NAINE
  • B. NINER
  • C. NOVEM
  • D. NINE
Answer: B — NINER
In the radiotelephone spelling of numbers used with the SMCP, 9 is pronounced NINER to avoid confusion with the German 'nein'. Similarly 3 is spoken TREE and 5 is spoken FIFE.

18. According to the SMCP, courses and bearings are always expressed

  • A. As 'left' and 'right' of the ship's head
  • B. In compass points only
  • C. In the 180 degree notation east or west
  • D. In the 360 degree notation, spoken as three separate figures
Answer: D — In the 360 degree notation, spoken as three separate figures
SMCP requires courses and bearings in the 360 degree notation from north, spoken digit by digit as three figures, for example 'zero-four-five degrees'. This avoids misunderstanding between ships of different nationalities.

19. In the SMCP, times are expressed

  • A. In the 24-hour notation, stating whether UTC, zone time or local time is used
  • B. Only in ship's time without any indication
  • C. In the 12-hour notation with a.m. and p.m.
  • D. In minutes after midnight
Answer: A — In the 24-hour notation, stating whether UTC, zone time or local time is used
SMCP standard phrases require times in the 24-hour notation, indicating whether UTC, zone time or local shore time is being used. This avoids the ambiguity of a.m. and p.m. in radio communication.

20. On VHF radiotelephone, the phrase used to ask the other station to repeat its last message is

  • A. Roger
  • B. Say again
  • C. Wilco
  • D. Over
Answer: B — Say again
'Say again' is the standard phrase to request repetition of a message or part of it. 'Over' ends a transmission when a reply is expected, and 'Roger' only confirms that the message was received.

21. In radio communication, the procedure word 'OUT' means

  • A. Change to another channel
  • B. Please reply now
  • C. Repeat your last message
  • D. The communication is ended and no reply is expected
Answer: D — The communication is ended and no reply is expected
'OUT' is used at the end of an exchange to show that the communication is finished and no reply is expected. 'OVER' is used at the end of a transmission when a response is expected; the two are never used together.

  • A. MSC.1/Circ.1182
  • B. A.918(22)
  • C. A.893(21)
  • D. A.1047(27)
Answer: B — A.918(22)
The IMO SMCP were adopted in 2001 by Assembly resolution A.918(22). They replaced the earlier Standard Marine Navigational Vocabulary and are the basis of Maritime English training referred to in IMO Model Course 3.17.

23. A blue circular safety sign on board, such as one showing a person wearing goggles, means

  • A. Warning of a hazard
  • B. A mandatory action that must be carried out
  • C. A prohibited action
  • D. Location of an escape route
Answer: B — A mandatory action that must be carried out
Under the safety sign colour system (ISO 7010) blue circular signs are mandatory signs, for example 'wear eye protection'. Red circles with a bar are prohibitions, yellow triangles warnings and green signs safe conditions.

24. A green rectangular safety sign showing a running man and an arrow indicates

  • A. A first aid prohibition
  • B. A fire extinguisher location
  • C. A no-entry area
  • D. An emergency escape route or exit

Green rectangular or square signs are safe condition signs, such as escape routes, emergency exits and first aid. Reading and understanding such safety instructions is part of the Maritime English syllabus.

25. A yellow triangular sign with a black border on a door or equipment means

  • A. Warning of a hazard such as high voltage or a hot surface
  • B. An instruction that must be obeyed
  • C. Safe condition or emergency exit
  • D. Location of fire-fighting equipment
Answer: A — Warning of a hazard such as high voltage or a hot surface
Yellow triangular signs with black border and symbol are warning signs indicating a hazard, for example electricity, hot surfaces or toxic material. They advise caution rather than prohibit or command an action.

26. The 'monkey island' on a merchant ship is

  • A. The open deck above the wheelhouse, where the standard magnetic compass is usually fitted
  • B. The small platform at the top of the foremast
  • C. The store room under the forecastle
  • D. The deck at the stern used for mooring
Answer: A — The open deck above the wheelhouse, where the standard magnetic compass is usually fitted
The monkey island is the uppermost deck on top of the wheelhouse. It normally carries the standard magnetic compass, radar scanners, flag mast and halyards, and sometimes the whistle, as listed in the GP rating syllabus 1.7.7.

27. The bulwark of a ship is

  • A. The plating forming the bottom of the ship
  • B. The watertight wall between two cargo holds
  • C. A raised platform at the bow for the anchor windlass
  • D. The steel plating along the ship's side above the weather deck that protects persons and deck cargo from the sea
Answer: D — The steel plating along the ship's side above the weather deck that protects persons and deck cargo from the sea
Bulwarks are the steel plating fitted along the side of the ship above the weather deck edge. They protect crew and deck fittings from the sea and prevent persons and objects falling overboard.

28. Freeing ports are fitted in the bulwarks to

  • A. Allow mooring ropes to pass through
  • B. Allow water shipped on deck to drain quickly overboard
  • C. Provide ventilation to cargo holds
  • D. Allow the anchor cable to run out
Answer: B — Allow water shipped on deck to drain quickly overboard
Freeing ports are openings at the bottom of bulwarks that let large quantities of water shipped on deck in heavy weather run overboard quickly. Trapped water on deck is dangerous because it adds weight high up and reduces stability.

29. The bulbous bow symbol painted on the hull near the stem is meant to

  • A. Mark the location of the forepeak tank air pipe
  • B. Show the maximum permitted draft forward
  • C. Indicate the position of the collision bulkhead
  • D. Warn tugs and small craft of the underwater bulbous bow projecting forward
Answer: D — Warn tugs and small craft of the underwater bulbous bow projecting forward
The bulbous bow mark warns tugs, pilot boats and other craft that a bulb projects forward below the waterline and could damage them if they approach too close. It is one of the hull markings listed in syllabus 1.7.1.

30. The bow thruster mark painted on the ship's side shows

  • A. The position of the bow thruster tunnel, which tugs and boats must keep clear of
  • B. The position of the anchor when stowed
  • C. The point where the pilot ladder must be rigged
  • D. The highest point of the load line
Answer: A — The position of the bow thruster tunnel, which tugs and boats must keep clear of
The bow thruster symbol warns tugs and small boats of the thruster tunnel below the waterline. Strong water currents from a running thruster can draw in or push away a boat, so craft must keep clear.
