Question 1

Collision avoidance, keep out of the way

Answer 1

I am going to take a regular series of compass bearings of the
APPROACHING vessel and if the compass bearing remains constant or
does not appreciably change and range is decreasing, then risk of collision is deemed to exist.

(Point at it) – This is the “stand on vessel”

I am the “keep out of the way” vessel and shall sound one short blast on the whistle of about one-second duration, make a bold alteration,
of course, to starboard (or port) of about 40 and 60 degrees. I will monitor the situation until finally past and clear and then return to its
original course.

Question 2

Rule 17 Action by stand-on vessel

Answer 2

I am going to take a regular series of compass bearings of the
approaching vessel and if the compass bearing remains constant or
does not appreciably change and range is decreasing then risk of collision is deemed to exist:

I am the Stand on Vessel. I shall maintain my course and speed.

I may, however, take action to avoid collision by my manoeuvre
alone, as soon as it becomes apparent that the other vessel is not
taking appropriate action in compliance with these Rules.

If so, I shall sound 5 short rapid blasts, inform the Master engage
hand steering. If there is no response, then sound 1 short blast and go
to starboard. (I can’t go to port for a power driven vessel at the may
stage.)

Not normally needed as we take action at the May stage

If the vessel required to keep her course and speed finds herself so
close that the action of the give-way vessel alone cannot avoid
collision.
I shall take such action as will best aid to avoid collision.(I can go to Port or Starboard at the final stage.)
I would sound 5 short blasts and take any action!

Question 3

Collision avoidance + shall not impede (inside a
Narrow channel or TSS)

Answer 3

I am going to take a regular series of compass bearings of the
approaching vessel and if the compass bearing remains constant or
does not appreciably change and range is decreasing, then risk of collision is deemed to exist:
This is Rule 18/15; I am the give-way vessel.
However, under rule 10 this vessel is required to not impede my safe
passage. I shall sound 5 short rapid blasts to remind her of her
obligation to not impede.
If there is no response then the normal Steering and Sailing Rules
apply when there is risk of collision and will act accordingly.

Question 4

You sight a CBD

Answer 4

I am going to take regular series of compass bearing of the
approaching vessel and if the compass bearings remain constant or
does not appreciably change and range is decreasing then risk of collision is deemed to exist.

I am the “shall not impede” vessel. I shall take early action to allow
sufficient sea room for the safe passage of the vessel not to be
impeded.

I will sound 1 short blast and alter to Starboard to parallel the other
vessel’s course (I will not alter to port for CBD on my own port side if
risk of collision exists).
