Part B: Section 1

Question 1

Define a lookout

Answer 1

Every vessel shall at all times maintain a proper lookout by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.

Question 2

Define safe speed

Answer 2

Can take proper and effective action to avoid a collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.

PE avoid C and SAD PCCs

Question 3

Factors affecting safe speed

Answer 3

Visibility
Traffic density 
Manoeuvrability 
Background lights (backscatter)
Wind, sea and current
Draught in relation to depth

Question 4

Factors affecting radar

Answer 4

Characteristics
Range
Weather
Ice and small vessels may not show up
Number of vessels
Exact assessment

Question 5

What means shall a vessel use to determine if a risk of collision exists

Answer 5

Use all available means appropriate to the prevailing circumstances and conditions

Question 6

Making assumptions

Answer 6

Do not make them based on scanty info especially scanty radar info

Question 7

Two ways to determine the risk of collision

Answer 7

Bearing of approaching vessel doesn’t change

Bearing changes but large vessel at close range or long tow

Question 8

What action taken to avoid a collision?

What do the rules say about any alteration of course/speed?

Answer 8

Positive, made in ample time and with due regard to the observation of good seamanship

Large enough to be clearly visible by sight or on radar, a small succession of movements should be avoided.

Question 9

Rules for a narrow channel

Answer 9

Keep as near to the starboard side as is safe and practical
PDV <20m, sailing and fishing vessels shall not impede the passage of a vessel which can only navigate within a narrow channel
Do not cross a narrow channel if you will impede CBD

Question 10

Separation schemes

Answer 10

Vessel shall
Travel in the correct direction
Keep clear of a traffic separation line or zone
Join or leave at the termination if necessary join at as small an angle as possible

Avoid crossing, if necessary right angles

Inshore traffic zone: <20m sailing vessels fishing vessels, en route to a port, to avoid immediate danger

Separation zone/line: emergency to avoid immediate danger fishing or crossing
