Situations Flashcards
Collision Avoidance, keep out of the way.
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 then risk of collision is deemed to exist. If risk of collision is deemed to exist or the CPA is unacceptable then:
(Point at it) – this is the “stand on vessel” that shall maintain its course and speed whilst monitoring the situation (point at it) – this is the “keep out of the way” vessel and she shall sound one short blast on the whistle of about one second duration, make a bold alteration of course to starboard of about 40 and 60 degrees. It will monitor the situation until past and clear and then return to its original course. If the Keep out of the way vessel does not keep clear then the Stand on vessel shall take such action as will best aid to avoid collision. It will sound 5 short rapid Blasts, inform the Master engage hand steering. If the other vessel is on the port side, It shall sound one short blast on the whistle of about one second duration and alter course to starboard to parallel the course of the vessel .It will monitor the situation and then sound one short blast of about one second duration and alter course to starboard to make the reciprocal course of the other vessel. When finally past and clear it can alter course to starboard to return to its’ original course passing astern of the other vessel continuing to monitor the situation.
Collision Avoidance, shall not impede (inside a Narrow channel or TSS or you sight a CBD)
I am going to take regular series of compass bearing of the approaching vessel
and
if the compass bearings remain constant or do not appreciably change then risk of collision is deemed to exit. If risk of collision is deemed to exist or CPA is unacceptable then:
(point at it) This is the “not to be impeded” vessel which shall continue with caution and monitor the situation (point at it)
This is the “shall not impede” vessel, it shall take early action to allow sufficient sea room for the safe passage of the vessel not to be impeded. If the vessel not to be impeded finds itself in a close quarters situation it shall sound 5 short rapid blast and if no response then the Steering and Sailing Rules apply when there is risk of collision and will act accordingly.

Sound 5 short RAPID blasts
Inform the master
Engage hand steering
and if there is no response then I shall make a broad alteration of course to STBD to parallel her course

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 then risk of collision is deemed to exist
This is rule 18 however vessel iengaged in fising is required not to impede me
I shall sound 5 short rapid blasts
If there is no response, then the normal steering and sailing rules apply, I would Slow Down

This is a vessel aground
Therefore
STOP the vessel
Inform the master
Carry out a chart assessment
and I would APEM to safety
work out what she went aground on, and see whether she requires any assistance

You are on a 50m motor yacht and you sigh this? what are you going to do?
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 then risk of collision is deemed to exist
I would determine if ROC exists, i am required not to impede and make a broad alteration of course to STBD
If you onboard RAM or NUC then we would be stand on, then she would require to keep out of our way
I see only a stern light of a ship, 20 dehrees to my stb side, risk of collision exists. What am i going to do?
Rule 13 CROSSING
1 short blast, make a broad alteration of course to STBD to show a positive action change
We are following a TSS, and you sight this, what are you going to do?

Rule 10 only applies when both inside TSS
What are you going to do?
Head on Situation
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 then risk of collision is deemed to exist
TSS, your actions and why?
What would you expect from the other vessels?
I am required to keep out of the way of the vessel on my STBD side

I Shall maintain my course and speed, I may, however, take action by my maneuver alone as soon as it becomes apparent that the other vessel is not taking action in compliance with the rules
If so, i shall sound 5 short RAPID blasts, inform the master, engage hand steering
and
if there is no response, I shall sound one short blast and make a bold alteration to STBD to parallel her course
Narrow channel, what are you going to do here?
Ask the examiner, whether we can navigate outside the narrow channel?
If we can only navigate outside the narrow channel then it is a crossing situation

This is a crossing situation and i am the stand on vessel however under rule 10 a vessel less than 20m is required not to impede me
I would sound 5 short RAPID blasts to remind her of her obligation
I am stand-on vessel, I shall maintain my course and speed
I may however take action
If so, I shall sound 5 short RAPID blasts, inform the master, engage hand steering
No response?
I would SLOW DOWN
What is this? and what would you do?
This is a vessel aground
I would STOP, engage hand steering, inform the master
do a chart assessment
APEM to safety

I would sound 1 short blast and make a broad alteration to STBD
We are following a TSS and sight this boat, what would you do?
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 then risk of collision is deemed to exist
Rule 15 - Crossing I am give way and in a TSS
I WOULD SLOW DOWN
What would you do?
PDV engaged in towing

you are on a 50m, what would you do?
Rule 18 - Responsibilities between vessels
I would sound 1 short blast and go to STBD
You are following a narrow channel and you sight this vessel, what are you going to do?
Can I confirm sir? can i navigate outside the narrow channel? NO
Okay, this is a crossing situation between two PDV
however under rule 9, I would expect no vessel shall cross a narrow channel if such a crossing shall impede the safe passage of another vessel within a narrow channel
I would sound 5 short blasts to remind her of her obligation not to impede
if she did impede, I would be the stand-on vessel
I shall maintain my course and speed
I may however take action and slow down,
I would engage hand steering, inform the master
What is this/ what are your actions?
vessel engaged in mine clearance operations
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 then risk of collision is deemed to exist
Inform the master, Stop, call them on the radio, find safest place to go
where is safe water?

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 then risk of collision is deemed to exist
Rule 13 Overtaking
Port or STBD - Positive aspect change
What is this? and your actions?
Vesssel at anchor, sound 1 short blast and go to STBD to go behind
What is this and what would you do?
This seems to be a sailing vessel with a day shape indicating that she is under power therefore
Rule 15 Crossing
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 then risk of collision is deemed to exist
Sound 1 short blast and make a broad alteration to STBD
You are onboard vessel A, what would you do?
Can I confirm if vessel is more than 22.5 degrees above my beam? Yes
I am stand on
SHALL.MAY.SHALL
Shall maintain my course and speed,
I may take action by my maneuver alone as soon as it becomes apparent that they arent complying with the rules
if so, i would sound 5 short rapid blasts
Bold alteration - go to Port
Once overtaking - All overtaking
