Q

What are the first 6 factors should be taken into consideration when determining a safe speed in rule 6?

A
  • state of visibility
  • traffic density
  • manoeuvrability of vessel
  • presence of background lights at night

Q

What is rule 7?

A
  • Risk of collision - all available means including radar should be used to determine the earliest warning of risk of collision.

Q

What is rule 8 part c?

A

If there is sufficient sea room, alteration of course alone may be the most effective action to avoid collision provided it is substantial, made in good time and doesn’t result in another close quarters situation.

Q

What is rule 8 part d?

A

The result of action to avoid collision should be to pass at a safe distance. The effectiveness of the action should be checked until the other vessel is past and clear.

Q

What does SAILING VESSEL mean?

Study These Flashcards
A

Any vessel under sail providing that propelling machinery is not being used.

17
Q

What does NOT UNDER COMMAND mean?

Study These Flashcards
A

A vessel which through exceptional circumstances is unable to manoeuvre as required so can not keep out of the way of other vessels.

17
Q

What does the term SEAPLANE mean?

Study These Flashcards
A

Any aircraft designed to manoeuvre on water.

18
Q

What does it mean when a vessel is RESTRICTED IN HER ABILITY TO MANOEUVRE?

Study These Flashcards
A

When a vessel from which it is in the nature of her work is restricted in her ability to manoeuvre so is unable to keep out of the way of other vessels.

19
What does it mean when a vessel is CONSTRAINED BY DRAUGHT?
When a power driven vessel is severely restricted in her ability to deviate from her course because of her draught in relation to the depth and width of available navigable water.
20
What does UNDERWAY mean?
When a vessel is not at anchor or aground or made fast to the shore.
21
What does Length and Breadth mean?
A vessels overall length and greatest breadth.
21
Under what circumstance are vessels deemed to be IN SIGHT OF ONE ANOTHER
When one can be observed visually from the other.
21
What does RESTRICTED VISIBILITY mean?
Any condition is which visibility is restricted.
21
What is a WING IN GROUND (WIG) CRAFT?
A multimodal craft which flies in close proximity to the surface of the water by utilising the surface-effect action.
21
What can vessels under 20m and sailing vessels not do in a narrow channel or fairway? (rule 9)
Impede the passage of vessels which can only safely navigate in a narrow channel or fairway.
21
What is rule 9 part a?
A vessel navigating a narrow channel or fairway should keep as near to the outer limit of the channel on her starboard side as long as it is safe.
22
What type of vessel should not impede the passage of any vessels navigating in a narrow channel or fairway? (rule 9 - part c - part b)
Vessels engaged in fishing.
23
When can a vessel not cross a narrow channel of fairway? (rule 9 - part d)
When it impedes the passage of a vessel that can only safely navigate within the narrow channel or fairway.
24
What sound signals should be heard when ships are overtaking in a narrow channel? (rule 9 - part e)
The vessel overtaking should either: - 2 long blasts and 1 short blast (if overtaking on stbd side) - 2 long blasts and 2 short blasts (if overtaking on port side. If the vessel being overtaken agrees, she should sound: - one long, one short, one long, one short blast.
25
What should vessels do in a narrow channel if they are nearing a bend and can't see other vessels? (rule 9 - part f)
Navigate with alertness and caution. The vessel should also sound one prolonged blast which should be reciprocated by the other vessel if present.
26
What is rule 9 part g?
Vessels should avoid anchoring in a narrow channel.
27
What are the second 6 things that should be taken into account when determining safe speed in rule 6?
- Characteristics, limitations and efficiency of the radar. - Any constraints imposed by the radar range scale in use. - The effect of interference on the radar such as the detection of sea state and weather. - The possibility that small objects, vessels and other floating objects may not be detected by radar. - The number, location and movement of vessels detected by radar. - The more exact assessment of visibility when radar is used to determine the range of other vessels and objects in the vicinity.
28
What does rule 10 apply to?
Traffic separation schemes and does not relieve any vessel of her obligation of any other rules.
29
What does rule 10 part b say?
A vessel using a TSS shall: - Proceed in the appropriate traffic lane and in the general direction of the traffic flow in that lane. - As long as practicable, keep clear of any traffic separation lines or zones. - Normally leave a lane at the termination point but if leaving from either side so at as small an angle to the general direction of traffic flow as possible.
30
What are the rules concerning crossing traffic lanes in rule 10 part c?
Crossing lanes should be avoided but if it has to be done then the ship should cross on a heading as closely practicable to right angles to the general direction of traffic flow.
31
What are the rules regarding inshore traffic zones? (rule 10 - part d)
- A vessel should not use a inshore traffic zone if she can safely navigate within the appropriate traffic lane. - Vessels less than 20m, sailing vessels and vessels engaged in fishing can use the inshore zones. - A vessel may use an inshore zone if en route to a port, offshore installation, pilot station or any other place situated within the zone, or to avoid immediate danger.
32
What are the exceptions (other than crossing vessels or vessels joining or leaving a lane) for entering a separation zone or crossing a separation line?
- Vessels in emergency or avoiding immediate danger. - To engage in fishing within a separation zone.
33
What should a vessel do if it is near the termination of a TSS? (rule 10 - part f)
Navigate with caution.
34
What is the rule concerning anchoring in a TSS? (rule 10 - part g)
Vessels should avoid anchoring in a TSS and near its termination points.
35
How wide should a vessel not using a TSS avoid it by? (rule 10 - part h)
As wide a margin as possible.
35
What should a vessel engaged in fishing not do in a TSS? (rule 10 - part i)
Impede the passage of any vessel following a traffic lane.
35
What kind of vessel should not impede the passage of a power-driven vessel following a traffic lane? (rule 10 - part j)
Vessels under 20m and sailing vessels.
36
What are the two situations in which a vessel does not need to follow the rules regarding traffic separation schemes? (rule 10 - parts k and l)
When a vessel that is RAM is carrying out an operation for the maintenance of safety navigation in a TSS. When a vessel that is RAM is engaged in an operation to lay, service or pick u submarine cables.
37
What is rule 11?
Rules in this section apply to vessels in sight of one another.
