2 x white in a line side lights
45
You are the Coxswain of an LCVP (length 15.7m) conducting a passenger transfer into
Liverpool. You have departed HMS ALBION in Liverpool Bay and have commenced your
passage towards the port. It’s early morning and the sun will rise around 30 minutes after
your departure. Visibility is currently good and winds are light; however, you’re aware that
fog patches have been reported by other vessels operating within the River Mersey.

and so fixed to show from right ahead to 22.5 ̊ abaft the beam on its respective side (1).
Sternlight – white light showing an unbroken arc of 135 ̊ and so fixed to show the light from
67.5 ̊ from right aft on each side of the vessel (1).
46
You can make out the lights of the buoys marking the main channel some distance ahead of
you and use them as a headmark. You find it quite difficult to see them against the
background lights ashore.
2. Other than the presence of background lights (such as from shorelights or from
backscatter of your own lights) name 2 other factors that shall be taken into account by all
vessels when determining a safe speed. (R.6(a))
The state of visibility;
The traffic density, including concentrations of fishing vessels or any other vessels

turning ability in the prevailing conditions;
The state of wind, sea and current, and the proximity of navigational hazards;
The draught of the vessel in relation to the available depth of water
47
Conscious that you’re struggling to see lights against the shoreline, you focus on
maintaining a proper lookout. Other than sight and hearing, name 2 other methods of
maintaining a lookout which are included in the term ‘all available means’. (R.5)
VHF radio
AIS
Radar
48

51
What action do you take and what should, if the circumstances of the case admit, be avoided? (R.15) we give way
I should keep out of the way (1) and shall, if the circumstances of the case admit, avoid crossing ahead of the other vessel (1)
52
You take the action required and, as you approach the entrance to Queen’s Channel,
it is starting to get light. You can easily make out both the port and starboard lateral marks
marking the main channel.
To which side of the narrow channel should you navigate? (R.9(a))
As near to the outer limit of the narrow channel which lies on our starboard side as is
safe and practicable (1)
53
Entering the channel, you note the following buoy on your port bow; it has a white
light which is on for 2 seconds, then off for 2 seconds (isophase 4s).
White and red vertical stripes
What type of buoy is this and what does it indicate? (NP100/NP735)
Given your answers above, to which side should we probably leave the mark
in this case? (NP100/NP735)
It is a safe water mark (1). It indicates that there is navigable water all around the
mark (1) and is likely here to indicate the centre of the channel.
On our port side (1), since it marks the middle of the channel and we are intending to
navigate as near to the outer limit of the channel which lies on our starboard side as
is safe and practicable.
54
You pass this navigation mark in accordance with the detail in your route card and
continue your passage along Queen’s Channel. Sunrise occurs and you turn off your
navigation lights. You sight ahead of you a merchant vessel passing Askew Spit; the
vessel is following the channel outbound.
(a). You assess that the other vessel can safely navigate only within the narrow
channel or fairway. What should we, as a vessel of less than 20m in length, avoid
doing? (R.9(b))
She has a black can hanging in the rigging.
What special condition does this shape indicate? (R.28)
How would she indicate this special condition at night? (R.28)
We should avoid impeding her passage (1)

Three all round red lights in a vertical line where can best be seen (1)
55
You safely clear the outbound merchant vessel and, on passing the statues in the sea at Crosby Beach, you notice on your port side a yacht with sails hoisted as shown below. The yacht appears to be crossing the channel along which you’re navigating.
You monitor the compass bearing of the yacht and it doesn’t appreciably change; the range to the yacht is however closing. What have you determined?
(R.7(d)(i))
If you were unsure whether risk of collision existed, what do the rules state that you should do? (R.7(a))
As you get closer to the yacht you notice the following shape in her rigging: Black cone apex down What does this signify? (R.25(e))
She is now 45 degrees on your port bow at a range of 800 yards; you assess that risk of collision exists. What situation exists and who is give way?
(R.15)
If you were in doubt as to whether the yacht was acting in compliance with the Rules in this case, what sound signal shall you make? (R.34(d))
If in this case, you decided to take action when she was at a range of 800 yards to avoid a close quarters situation, what action do the rules state should, if the circumstances of the case admit, be avoided? (R.17(c)
If you and the yacht became so close that collision could not be avoided by the action of the give way vessel alone, what action would be required of you? (R.17(b))
That risk of collision exists between our vessel and the yacht (1)
Assume that this is the case (i.e. risk of collision does exist) and act accordingly (1)
That she is also operating propelling machinery / under power (1) and is therefore a power driven vessel within the meaning of the Rules
A crossing situation (1) and the yacht is give way (1)
Sound at least 5 short and rapid blasts on the whistle (1)
A power driven vessel which takes action in a crossing situation, in accordance with sub-paragraph (a)(ii) of this Rule, to avoid collision with another power driven vessel, shall, if the circumstances of the case admit, not alter course to port for a vessel her own port side (1).
I should take such action as will best aid to avoid collision (1)
56
When is a vessel deemed to be overtaking in accordance with the Rules? (R.13(b))
You determine that you are overtaking the other vessel and that risk of collision continues to exist. What action is required of you in accordance with Rule 13? (R.13(a))
At what point is the overtaking vessel relieved of her obligation to keep out of the way of the vessel being overtaken? (R.13(d))
With plenty of searoom available, you decide that you will alter just your course to avoid the close quarters situation that is developing. The rules permit this providing that the course alteration meets 3 requirements – what are they?
(R8(c))
A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5 ̊ abaft her beam (1) that is, in such a position with reference to the vessel she is overtaking, that at night she would be able to see only the sternlight of that vessel but neither of her sidelights.
I am required to keep out of the way of the vessel being overtaken (1)
Only when she is finally past and clear (1) of the vessel she is overtaking.
The course alteration must be made in good time (1), be substantial (1) and should not result in another close quarters situation (1).
57
As you approach Seacombe and near your destination, you notice that a dense fog
bank is moving up the river and visibility rapidly reduces to around 600 yards.
(a) When does Rule 19 (Conduct of Vessels in Restricted Visibility) apply?
(R19(a))
(b) You turn on your navigation lights, post a lookout forward, review safe speed
and focus on the radar. Given that you’re now navigating in or near an area of
restricted visibility, what sound signals do you make and at what interval?
(R.34(a))
You detect a vessel by radar alone directly ahead of you. Using radar you
determine that she is on a reciprocal course (i.e. heading directly towards you) and
that risk of collision exists. What action is required of you and what manoeuvre
should, so far as possible, be avoided?
(R.19(d))
To vessels not in sight of one another (1) when navigating in or near an area of
restricted visibility (1)
One prolonged blast at intervals of not more than 2 minutes (1)
I should take avoiding action in ample time (1) providing that when such action
consists of an alteration of course, so far as possible, the following should be
avoided: (a) an alteration of course to port for a vessel forward of the beam (1)
58
Action required in a head on situation (R.19/R.14)
As we’re now in sight of one another, it is a head-on situation (1) and each vessel
should alter her course to starboard so that each shall pass on the port side of the
other (1).
59
The fog clears as quickly as it descended and you safely pass the vessel continuing
your passage towards Liverpool Landing Stage. As you approach the landing stage
another vessel is departing and sounds 3 short blasts on their whistle. What does this
signal indicate? (R.34(a))
That she is operating astern propulsion (1)
60

admit, be avoided? (R.15/R.34) (3)
The term sailing vessel means any vessel under sail provided that propelling
machinery, if fitted, is not being used (1).
That she is operating propelling machinery (1) and she is now a PDV within the
meaning of the rules.
A crossing situation (1) between 2 power driven vessels.
I should keep out her way (1) either by making a bold alteration of course to
starboard to pass astern of her or by reducing speed / stopping to allow her to pass
ahead. I should make a sound signal if appropriate (1) e.g. one short blast if altering
to starboard. I should, if the circumstances of the case admit, avoid crossing ahead
of her (1).
64
You take the action required and safely pass the yacht resuming your passage
towards Cowes. On approaching Egypt Point you sight a Red Falcon passenger ferry on
your port bow at a range of 1.5nm. You assess that risk of collision exists between your
vessel and the ferry.
a. Given that risk of collision exists, what situation is developing and who is the
give way vessel? (R.15) (1)
b. What action do you take? (R.17(a)(i)) (1)
c. You take the necessary action but don’t understand the actions/intentions of
the ferry and are in doubt as to whether the ferry is acting in accordance with the
Rules. What sound signal should you make and is it optional or mandatory to make
the signal at this stage? (R.34(d)) (2)
d. When may you take action to avoid collision in this circumstance? (R17(a)(ii)) (1)
e. When do the rules state that a stand-on vessel shall take action to avoid
collision? (R.17(c)) (1)
If you decide to take action to avoid collision in this instance what shall, if the
circumstances of the case admit, be avoided? (R.17(d))
A crossing situation (1/2) is developing and the passenger ferry is the give way
vessel (1/2).
Keep my course and speed (1) but continue to monitor her closely.
At least five short and rapid blasts on the whistle. (1)
It is mandatory (1) since Rule 34(d) states that ‘when vessels in sight of one another
are approaching each other and from any cause either vessel fails to understand the
actions or intentions of the other vessel, or is in doubt whether sufficient action is
being taken by the other to avoid collision, the vessel in doubt shall immediately
indicate such doubt by giving at least 5 short and rapid blasts on the whistle’.
As soon as it becomes apparent to me that the vessel required to keep out of the way
is not taking appropriate action in compliance with the Rules. (1)
When, from any cause, a vessel required to keep her course and speed finds herself
so close that collision cannot be avoided by the action of the give way vessel alone.
(1)
An alteration of course to port. (1)
65
5. On clearing Cowes you sight a small vessel engaged in fishing (trawling).
a. What shapes would you expect her to show by day? (R.26(b)(i)) (1)
Two cones, apexes together in a vertical line one above the other (1) or diagram
shown:
66
In accordance with Rule 18 (Responsibilities Between Vessels), except where
Rules 9, 10 and 13 otherwise require, which types of vessel are required to keep out
of the way of a vessel engaged in fishing? (R.18 (a)(b))
Power driven vessels (1) and sailing vessels (1)
(sea plane /WIG ?)
67
You pass south of the fishing vessel and remain to the south of Ryde Middle. Looking ahead you can see a very large merchant vessel inbound displaying the following shape in her rigging: What does this shape signify? (R.28) (1) A Black Can
What should we, as a vessel of less than 20m in length, avoid doing with
respect to this vessel? (R.18(d)(i)) (1)
If risk of collision existed with this merchant vessel and we were the stand on
vessel, would we still be required to take action to avoid impeding her safe passage?
(R.8(f)(ii))
That she is a vessel constrained by her draught (1).
We should, if the circumstances of the case admit, avoid impeding her safe passage
(1).
Yes – we are still obliged to avoid impeding her safe passage (1), Rule 8(f)(ii) states that ‘a vessel required not to impede the safe passage of another vessel is not relieved of this obligation if approaching the other vessel so as to involve risk of collision and shall, when taking action, have full regard to the actions which may be required by the rules of this part’.
68
Continuing your passage to Portsmouth, you notice ahead of you a small power
driven vessel / pleasure craft which you are overhauling:
When is a vessel deemed to be overtaking in accordance with the Rules and
how could you recognise that such a situation was developing at night?
(R.13(b)) (2)
You determine that you are overtaking the other vessel and that risk of
collision continues to exist. What action is required of you in accordance with Rule
13? (R.13(a))
At what point is the overtaking vessel relieved of her obligation to keep out of
the way of the vessel being overtaken? (R.13(d))
With plenty of searoom available, you decide that you will alter just your
course to avoid the close quarters situation that is developing. The rules permit this
providing that the course alteration meets 3 requirements – what are they?
(R8(c))
A vessel shall be deemed to be overtaking when coming up with another vessel from
a direction more than 22.5 ̊ abaft her beam (1) that is, in such a position with
reference to the vessel she is overtaking, that at night she would be able to see only
the sternlight of that vessel but neither of her sidelights (1).
I am required to keep out of the way of the vessel being overtaken (1)
Only when she is finally past and clear (1) of the vessel she is overtaking.
The course alteration must be made in good time (1), it is substansial (1) and it does
not result in another close quarters situation (1).
69
You safely pass this vessel and continue your passage. The shipping situation is
busy with a high volume of fishing vessels, yachts and other pleasure craft. Other than
traffic density, name 2 other factors that should be taken into account by all vessels when
determining safe speed. (R.6(a))
Any 2 from the following (1 mark each):
The state of visibility.
The manoeuvrability of the vessel with special reference to stopping distance and
turning ability in the prevailing conditions.
At night, the presence of any background lights such as from shorelights or from
backscatter of her own lights.
The state of wind, sea current and the proximity of any navigational hazards.
The draught of the vessel in relation to the available depth of water.
70
As you pass to the North of Ryde Pier it starts to rain heavily as one of the forecast showers passes through. Visibility reduces to around 0.5nm.
a. When does Rule 19 (Conduct of Vessels in Restricted Visibility) apply?
(R19(a)) (2)
You turn on your navigation lights, post a lookout forward, review safe speed and focus on the radar. Given that you’re now navigating in or near an area of restricted visibility, what sound signals do you make and at what interval?
(R.34(a)) (1)
c. What lights should you now be displaying? (Arcs of visibility not required).
(R.23a) (3)
To vessels not in sight of one another (1) when navigating in or near an area of
restricted visibility (1)
One prolonged blast (1/2) at intervals of not more than 2 minutes (1/2)
Masthead light (1), sidelights (1) and sternlight (1).
71
You detect a vessel by radar alone and determine that risk of collision exists.
You decide to take avoiding action in ample time by altering course. What
manoeuvre should, so far as possible, be avoided if:
(i) The vessel is forward of your beam (but you’re not overtaking her)?
(R.19(d)) (1)
(ii) The vessel is on your beam or abaft your beam? (R.19(d)) (1)
An alteration of course to port (1)
An alteration of course towards the vessel (1)#
72
On clearing this vessel the visibility improves to in excess of 8nm. You pick up the
Swashway transit and make your way up harbour. As you approach 2 Basin to conduct the
transfer you realise that any vessels departing the basin will be obscured due to the narrow
entrance. What sound signal do you make prior to making your approach and how should
you navigate on entering the basin? (R.9(f)/R.34(e))
I should navigate with particular alertness and caution (1) and I should sound 1 prolonged
blast (1).
73
12. You safely enter 2 Basin and secure your vessel alongside. Having made your
vessel fast to the shore you are no longer deemed to be underway within the meaning of the
rules. Other than a vessel made fast to the shore, on what 2 occasions would you no longer
be considered to be underway within the meaning of the rules? (R.3(i)) (1)
When at anchor (1/2) or aground (1/2).
74
The shower passes through and visibility starts to improve; you now assess it to be
around 2-3 nm but it’s still quite gloomy. You leave your navigation lights on but cease
sound signals. Through the gloom, you sight the following navigation lights directly ahead
of you: White over red and both side lights
a. What type of vessel is this? (R.29)
b. Assuming that risk of collision exists, what situation is developing?
(R.14(b))
c. What action do you take? (R.14(a)/R.34(a)) (2)
It is a vessel engaged on pilotage duties (1)
It is a head on situation (1)
I would alter my course to starboard (1) and sound 1 short blast (1).
