Practice questions (with answers)

1. In a Rule 15 crossing encounter, the give-way vessel shall, if circumstances admit:

   1. AAlter course to port and pass ahead of the other vessel
   2. BHold her course and speed until the other vessel acts first
   3. CKeep well clear and avoid crossing ahead of the other vessel
   4. DIncrease speed so as to cross ahead of the other vessel quickly
   Show answer

   Correct answer: C. Keep well clear and avoid crossing ahead of the other vessel

   Rule 15 requires the give-way vessel to keep out of the way and, if circumstances admit, avoid crossing ahead. Rules 8 and 16 require early, substantial and effective action; the safe choice of course or speed depends on the whole situation.

2. The stand-on vessel MUST take action to help avoid collision when:

   1. AThe give-way vessel sounds one short blast while altering to starboard
   2. BCollision cannot be avoided by the give-way vessel acting alone
   3. CA third vessel enters the area and the situation becomes complex
   4. DVisibility becomes restricted during the encounter
   Show answer

   Correct answer: B. Collision cannot be avoided by the give-way vessel acting alone

   Rule 17(b): once so close that the give-way vessel alone cannot avoid collision, the stand-on vessel shall take action that best helps avoid it. Rule 17(a)(ii) separately permits earlier action when the give-way vessel is not taking appropriate action.

3. Except where Rules 9, 10 or 13 otherwise require, a power-driven vessel underway shall keep out of the way of all these EXCEPT:

   1. AA sailing vessel underway and not overtaking
   2. BA vessel not under command showing two red lights
   3. CAnother power-driven vessel of larger size
   4. DA vessel engaged in fishing with trawls
   Show answer

   Correct answer: C. Another power-driven vessel of larger size

   Rule 18(a): power-driven vessels give way to NUC, RAM, fishing, and sailing vessels — but size alone does not determine priority.

4. In restricted visibility, your vessel detects another by radar alone forward of the beam and needs to alter course to avoid collision. The target is not being overtaken. So far as possible, avoid:

   1. AReduce speed
   2. BAlter course to starboard
   3. CAlter course to port
   4. DUse sound signals
   Show answer

   Correct answer: C. Alter course to port

   Rule 19(d)(i): when course alteration is chosen for a radar-only contact, avoid a port alteration for a vessel forward of the beam, other than a vessel being overtaken.

5. How does IALA Region B differ from Region A?

   1. AThe lateral shapes swap sides — cans to starboard
   2. BThe colours are reversed — red to starboard
   3. CCardinal marks swap their black and yellow bands
   4. DOnly the topmarks differ
   Show answer

   Correct answer: B. The colours are reversed — red to starboard

   Region A: port-hand red, starboard-hand green. Region B: port-hand green, starboard-hand red. Interpret both in the charted conventional direction of buoyage.

6. An East Cardinal mark shows how many quick flashes?

   1. A1 flash
   2. B3 flashes
   3. C6 flashes + long flash
   4. D9 flashes
   Show answer

   Correct answer: B. 3 flashes

   White lights, when fitted: North Q or VQ; East VQ(3) 5 s or Q(3) 10 s; South VQ(6)+LFl 10 s or Q(6)+LFl 15 s; West VQ(9) 10 s or Q(9) 15 s. The long flash lasts at least 2 s.

7. If fitted, the topmark of an isolated danger mark is:

   1. AA single red sphere
   2. BTwo black spheres vertically
   3. CA yellow X-shape
   4. DTwo black cones, point to point
   Show answer

   Correct answer: B. Two black spheres vertically

   Isolated danger marks have two black spheres (balls) as topmark. (if fitted).

8. Safe water marks are used as:

   1. AMarks placed on an isolated danger
   2. BFairway or mid-channel marks
   3. CMarks for a special area or feature
   4. DPort-hand lateral marks
   Show answer

   Correct answer: B. Fairway or mid-channel marks

   Safe water marks are used as fairway, mid-channel, or landfall marks.
