Use these 25 questions for Rules

[박대선]

Use these 25 questions to help you review Rules 1 to 19.

1.      Where, and to which vessels, do the International Collision Regulations apply?

All vessels upon the high seas and in all waters connected.

2.      What do the Rules have to say about special rules made by local authorities?

Nothing shall interfere with the operation of special rules.

3.      What does Rule 1 have to say about vessels which cannot comply with the Rules due to the special nature of their construction or purpose? Give examples of such vessels.

Airplane carriers or those can not comply with the rules shall comply with as close as possible.

4.      Explain Rule 2 in your own words.

Always comply with the rules except to avoid immediate danger.

5.      Explain the difference between a “vessel not under command” and a “vessel restricted in her ability to manoeuvre”. Give at least two examples of each vessel.

Vessels of NUC can not manoeuvre due to engine or rudder issues whereas those of RAM would not for the nature or her works such as towing or cable laying.

6.      Define the following terms:

a.      Underway: not at anchor, or made fast to the shore, or aground

b.      vessel constrained by her draft: depth and width of water is not enough for her draft to manoeuvre

c.      vessel engaged in fishing: fishing with any apparatus which restrict manoeuvrability

d.      restricted visibility: visibility is restricted by water, sands, or any other similar causes

7.      When do Rules 5-10 apply?

It does any condition of visibility.

8.      Explain what is meant by the phrase “maintain a proper look-out”.

We should do it by not only by sight but by all available means.

9.      Define ”safe speed”, and list ten factors that should be among those taken into account by vessels with operational radar when determining a safe speed.

It enables proper and effective action to avoid collision.

By all vessels: visibility, traffic density, manoeuvrability, light at night, wind/sea/current, draught

By radar vessels: radar characteristics, radar constraints, sea interference, small non radar detectable, number of vessels, radar visibility

10.   What does Rule 7 say about the use of compass bearings in determining if risk of collision exists?

It exists if the bearing does not change evidently and may exist when the bearing changes specially a large vessel, a tow or at close range.

11.    What does Rule 8 say about alterations of course to avoid a close-quarters situation?

It shall be large enough and made in good time.

12.    Briefly describe the audible overtaking signals used in narrow channels internationally and under Canadian modifications.     

Two prolonged & one/two short blast to overtake for internationally and one/two short blast for domestically

13.   What does Rule 9 state about vessels crossing a narrow channel or fairway?

Do without impeding the passage of vessels in the channel or fairway.

14.   Describe how vessels must navigate in a Traffic Separation Scheme.

Proceed in the appropriate lane; keep far clear of a separate lane; join/leave at the termination of the lane or as small angle as possible from general direction

15.   What vessels, other than crossing vessels, are permitted to cross a separation line or enter a separation zone?

Emergency to avoid danger; to engage in fishing within a separation zone.

16.   When do Rules 12-18 apply? It does in sight of one another.

17.   Briefly describe the conduct of two sailing vessels approaching each other as to involve risk of collision, as required under Rule 12. 

Out of way vessel: wind on the port first; windward if both on the port

18.   According to Rule 13 (including Canadian modifications), what defines an overtaking situation? Does this rule apply in restricted visibility?

No, coming up with the other vessel whose stern light visible position without side lights; The overtaking shall keep out of the way of the overtaken.

19.   According to Rule 14, what defines a head-on situation? What action is required of the vessels involved? 

Seeing the other’s master and both side lights visible position, each shall alter her course to starboard.

20.   State the requirements of Rule 15 for two power-driven vessels crossing so as to involve risk of collision.

The vessel whose starboard side has the other shall keep out of the way.

21.   Define give-way vessel and stand-on vessel. Briefly describe the responsibility of each. (Particularly, consider the responsibility of the stand-on vessel in relation to the four stages)

The vessel which is directed to keep out of the way is give-way vessel whereas the other is stand-on vessel. Give-way shall take early and big enough action and stand-on shall keep original when collision could be avoided. She shall do best aid to avoid collision when give-way’s action is not enough. She shall not alter course to port whenever possible. It does not relieve the give-way’s obligation. 1) At long range, both are free to take action 2) When risk begins, SO must keep original 3) When GW does not act, SO gives ….. and may takes action 4) When collision avoiding is impossible, SO must take action.

22.   Outline the hierarchy of responsibilities between vessels as required by Rule 18.

Which three rules override these responsibilities?

Except rule 9, 10, and 13, NUC has highest priority, RAM next, limited draught, engaged in fishing, sailing, power-driven, seaplane, WIG.

23.   When does Rule 19 apply? It applies not in sight of one another.

24.   What must every vessel do when proceeding in conditions of restricted visibility?

Every vessel shall proceed at a safe speed adapted to the circumstances.

25.   So far as possible, when taking avoiding action in restricted visibility, what course alterations should be avoided?

Port for a vessel forward of beam except overtaking and toward a vessel abaft.
