The positions of the ship provided by the GPS receiver should always be verified by other means. Which of the following suggested methods would be the most accurate?
Bearing and distance from a navigational buoy.
Radar bearings of three distinctive shore objects.
A DR updated position from the last reliable one.
Radar ranges of three distinctive shore objects.
After passage planning with ECDIS, how should the route be checked for safety?
Investigate the displayed waypoint list after it is printed out.
Transfer the ECDIS plan onto paper charts.
Using the ECDIS route checker and by visually sighting all along it.
Using the ECDIS route and geometry checker only.
Can the OOW be the sole lookout?
When the visibility is good and the ship is in the middle of the ocean where there is very little shipping.
Never should the Officer of the Watch be the only lookout.
During daylight when visibility and traffic allows.
Only if the ARPA radar is set onto Auto Acquisition with an audio alarm sounding when a ship is detected.
The ship is drifting in the open sea with a temporary engine breakdown. The ship is equipped with GPS navigation equipment. What should the bridge Officer of the Watch do in this situation?
Keep a good lookout for other ships.
Display the “Not under Command” signal and switch off the normal steaming lights.
All of the possible answers.
Plot the direction and rate of drift and predict the ships position for the period while the ship is “Not Under Command”.
What actions should the Officer of the Watch take when the ship’s steering gear fails?
Display the NUC signal and consider stopping the engines.
Request the engine room to check the steering gear.
All of the suggested answers.
Call the Master and advise him of the situation.
The tug has been released and is all clear. As officer in charge of that operation, should this be reported and to whom?
Reported all clear to the Bridge.
No need for reporting as the order was given from the bridge.
Report all clear to the tug.
Report all clear to the Engine Room.
The bridge Officer of the Watch (OOW) is plotting the ship’s position in the chartroom, when the ship is in collision with a fishing vessel. Why would the OOW be held responsible for the collision?
Under the Rules a proper lookout should be maintained at all times and by all available means.
If the OOW is busy with the safe navigation of the ship he should have exhibited the “Not under Command” signals and made other ships keep clear.
If risk of Collision existed, the fishing boat should have contacted the larger ship over the VHF before the collision took place.
Under the Rules the fishing vessel should have kept clear of larger vessels and the OOW would not be responsible.
The ship is sailing in shallow water with reduced Under Keel Clearance. If the ship is steaming with the engines at full RPM, what would be the speed in comparison to the speed achieved in deep water?
Slower than deep water.
It would be very difficult to maintain full deep sea RPM on the engines and therefore difficult to assess the speed.
Faster than deep water.
The same as deep water.
You are proceeding up a river, with berths on both banks. You see this flag hoist on a vessel moored on a berth ahead. What does it mean?
You should proceed at slow speed when passing me.
I am about to depart the berth.
My engine is disabled.
Caution! I have an anchor down.
Two ships are meeting in a restricted channel as illustrated. Which of the following actions would be the most suitable to take on both vessels as they approach and pass each other?
Slow down if possible without losing steerage and be prepared for prompt application of rudder to counteract any swing as they approach and pass each other.
Increase speed slightly to pass each other as quickly as possible and thereby reduce the effects of “ship to ship” interaction.
Maintain speed and a straight course on the starboard side of the channel.
Keep as far as possible on the starboard side of the channel and maintain speed to retain effective steerage.
Where can the size of the Magnetic Compass Error be found?
By reference to the last entry in the Compass Error Log Book.
By taking a transit bearing of two fixed geographical positions and comparing it with the bearing of the same points on the chart.
On the chart in the centre of the compass rose or by reference to the Variation chart, taking into account the annual changes.
By taking the error from the Deviation Table on the bridge.
When fastening synthetic fibre ropes such as polypropylene on bitts, for safety and better rope control it is recommended to:
Make it fast in a figure of eight fashion, fig. 3.
Make it fast with round turns on the leading bitt alone, fig. 1.
Make two round turns fast on the leading bitt and then figure of eight on both bitts, fig. 4.
Make it fast on the second bitt alone, fig. 2.
What is the depth of an iceberg below the surface of the sea?
The draught of an iceberg varies with the type of berg and its age.
The depth of an iceberg below the surface is always about one sixth of its total depth.
The draught of an iceberg is about the same as the visible part of the iceberg above the water.
The draught of an iceberg is normally about 3/4 of its total depth.
You are approaching the port entrance. What do these lights mean?

Immediately answer the distress message on the correct radio frequency.
Determine how close your vessel is to the distressed vessel.
Contact SAR Authorities via nearest coast Radio station.
Listen for a distress message on the appropriate radio frequency for five minutes.
Rule 12 of the International Collision Regulations prescribes the action to be taken by a sailing vessel when meeting another sailing vessel. This depends on the direction of the wind relative to each vessel. In the situation shown here, which sailing vessel (A or B) must keep out of the way of the other?
The upwind sailing vessel must keep out of the way of the downwind sailing vessel.
Both sailing vessels are required to take avoiding action.
Sailing vessel A must keep out of the way of sailing vessel B.
Sailing vessel B must keep out of the way of sailing vessel A.
What is the correct understanding of the term “bank effect”? If a ship was approaching the bank at an angle, what would be the effect on the ship?
The vessel’s bow is pushed away from the bank.
The whole vessel would continue straight towards the bank and would require a large helm order to avoid going aground.
The vessel’s stern is pushed away from the bank.
The vessel’s bow is attracted by the bank.
What does this flag mean?
I have a diver down; keep well clear at slow speed.
Yes (affirmative).
My vessel is stopped and making no way through the water.
I wish to communicate with you.
You are on a power-driven vessel underway in open water. This vessel is sighted directly ahead. The distance is closing slowly. What action will you take under the International Collision Regulations and why?
The vessel is on a steady bearing and the distance is closing. I will therefore take avoiding action, altering course to starboard and sounding one short blast under rules 14 and 16.
I will maintain my course and speed. The other vessel is being overtaken and is therefore obliged to keep out of the way by rule 13.
I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.
When a ship is lying at anchor in a tidal area using both forward anchors, to what particular aspect should the officer of the watch be paying special attention?
The two anchors will restrict the ships swing with the tide and the ship may not lie to the prevailing current and wind.
The tension on both cables should be similar, to avoid one dragging and all the weight of the ship remaining on the other anchor only.
When the ship swings to the tide the direction of swing should be controlled to avoid the anchor cables becoming wrapped round each other.
The ship will become controlled by the tide and the wind will not be allowed to have any effect on the direction the ship lies at anchor.
A ship is equipped with a right-handed fixed pitch propeller, which when going from Full Ahead to Full Astern will make the ship sheer to starboard. Can anything be done to reduce this change in heading?
The rudder can be put from side to side in a “Rudder Cycling” movement.
The rudder should be put Hard to Port to reduce the water flow to the left side of the propeller.
The rudder can be put to Hard to Port to reduce the water from to the right side of the propeller.
The rudder should be kept amidships when going astern and there is little that can be done to reduce the swing to starboard.
Can anything be done on a vessel with forward speed, to reduce the change in heading caused by a right hand fixed pitch propeller being put astern?
Yes, the rudder can be put to port.
No, the rudder should be kept amidships when going astern and there is little that can be done to reduce the swing to starboard.
The rudder can be cycled from side to side.
The rudder should be put hard to starboard to reduce the water flow to the left side of the propeller.
What is the colour and characteristic of a “towing light”, as defined in the International Regulations for Preventing Collisions at Sea?
One of two all-round amber, alternate flashing lights, displayed where they can best be seen.
White, fixed, displayed as an additional light on the foremast over an arc of 225°, from right ahead to 22,5° abaft the beam on each side of the vessel.
Yellow, fixed, seen over an arc of 135° and so arranged as to display 67,5° from right aft on each side of the vessel.
Amber, all-round, flashing, where it can best be seen.
Two ships travelling in opposite directions are to pass each other in a narrow river, as illustrated. Explain what is likely to happen as they pass each other?
Due to interaction, the bows will attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.
Due to interaction, the bows will repel each other, and then when alongside each other the two ships will be sucked together and finally the sterns will be repelled as they start to pass clear.
As they approach, rudder should be applied quickly to avoid sheering into the path of each other. Then as they are alongside they will be attracted and finally repel each other as they pass clear.
There will be very little effect between the two ships as they pass.
Which of the following figures drawn on the plane of the Meridian is correct for an observer in position Latitude 30° 00′ North; Longitude 15° 00′ West, when observing the sun on the meridian, if the sun’s Declination is 15° 00′ South?
Figure 3 is correct.
Figure 2 is correct.
Figure 1 is correct.
Figure 4 is correct.
The ship has a right-handed propeller and is swinging to starboard when the engines are slow ahead and the rudder is to starboard. The engines are stopped and the rate of swing rapidly slows down. How could the swing to starboard be maintained without the ship making much headway.
By applying the rudder hard over to starboard and going ahead on the engines.
Astern on the engines will allow Transverse Thrust to continue the swing.
The only effective method is by using the bow thruster to push the bow to starboard.
Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.
Which is the “CENTRE LINE”, in the figure?
The Fore and aft Centreline is indicated by D, in the figure.
The Fore and aft Centreline is indicated by A, in the figure.
The Fore and aft Centreline is indicated by C, in the figure.

Why should Ground Stabilised True Motion display mode be avoided when using the ARPA for anti-collision purposes?
The Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
The true vector can never give an indication of collision risk with another ship.
The collision regulations are based on ship courses through the water.
True motion does not provide the collision risk of other ships.
During an STS operation with one ship at anchor, should an anchor watch be maintained?
Anchor watch responsibility rests with the discharging vessel which would be the vessel which is anchored.
Anchor watch responsibility rests with the vessel which has its anchor down and the ship to ship connections is the responsibility of the other vessel.
Both ships have normal anchor watch responsibility in addition to watching ship to ship fendering, mooring etc.
Anchor watches are not kept as the duty officers will be on deck conducting the cargo operations.
What would be considered the most favourable heading of a ship when launching a lifeboat?
The ship should lie stopped in the water with the weather on the opposite side to the boat to be launched.
The ship should steer about 100° of the prevailing weather and sea with the boat to be launched on the leeside.
The ship should steer with the prevailing weather and sea on the beam and the boat to be launch on the leeside.
The ship should steer about 30° off the prevailing weather and sea with the boat to be launch on the leeside.
When splicing an eye on a mooring wire (using the recommended 5 full tucks and 2 half tucks) the effective breaking strength of the wire may be affected by the splice. What would be the anticipated change in the breaking strength of the wire?

The continual changes of courses steered by the ship.
Deviation and Variation.
Permanent and induced magnetism in the ships structure.
Two mooring lines are pretensioned equally and have the same length, same breaking strength and same directional load. However, one is made of wire (with a full load elastic elongation of about 1,5 % of its length) and the other made of nylon (with a full load elongation of about 30 % of its length). If a gust of wind increases the load on the lines, how will it be shared?
Wire takes 45 % of the extra load. Rope takes 55 % of the extra load.
Wire takes 55 % of the extra load. Rope takes 45 % of the extra load.
The wire and rope will share the load equally.
Wire takes 95 % of the extra load. Rope takes 5 % of the extra load..

How can a new officer, just boarding a ship, ensure that he knows the location and operation of all navigational and safety equipment and take account of the operating limitations of such equipment?
By using the equipment on regular watchkeeping duties.
By following the standard company Induction procedures for a bridge watchkeeping officer.
The certificate of competency will ensure the officer has suitable competence in operating the bridge equipment.
By asking other officers and practicing with the use of the equipment.
The ship has a single fixed pitch right-handed propeller and is going astern as illustrated. What is the most likely way the ship will react in these circumstances?
The ship will go straight astern and the heading will remain approximately the same.
The stern will fall off to starboard, making the heading swing to port.
The stern will “back” into the wind and the ship’s heading will swing to starboard.
The bow will “seek” the wind and the ship will swing to port.
What is the correct understanding of the term “Block Coefficient” as applied to a ship?
The comparison of the underwater shape of the ship, to a rectangular block of the same extreme dimensions.
The ratio of the water plane shape of the ship to a rectangle of the same extreme dimensions.
The coefficient of a Block and Tackle.
The restriction of a valve in a pipe to the flow of fluid through that pipe.
Ships vary considerably in design and underwater shape, but does the ship’s trim ever have any influence on its steering abilities?
Yes, a ship often steers better if trimmed by the bow.
No, the ship will have the same steering ability and is unaffected by trim.
No, it is usually best to be on an even keel and have no trim at all.
Yes, the ship often steers better if trimmed by the stern.
Why should a Ground Stabilised True Motion radar display not be used for anti-collision purposes?
True motion does not provide the collision risk of targets as only true vectors are available.
The true vector can never give an indication of collision risk with another ship.
The “aspect” of the target is confused, so the Regulations for Preventing Collisions cannot be accurately applied.
Because this display is only ever used for navigation.
What could be the reason for the magnetic compass to swing through large angles when the ship is rolling in a seaway?
The heeling error magnets are upside down and/or not in the correct position.
The Coefficient B determined by the Compass Corrector at the last dry-dock was not correctly calculated.
The error due to deviation is large for that ships heading.
The induced magnetism from the earth’s magnetic field is very strong in that area.
Two ships travelling in opposite directions are to pass each other in a narrow river, as illustrated. Explain what is likely to happen as they pass each other?
Due to interaction, the bows will repel each other, and then when alongside each other the two ships will be sucked together and finally the sterns will be repelled as they start to pass clear.
There will be very little effect between the two ships as they pass.
Due to interaction, the bows will attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.
As they approach, rudder should be applied quickly to avoid sheering into the path of each other. Then as they are alongside they will be attracted and finally repel each other as they pass clear.

Yes, for the reasons stated in all of the suggested answers.
Yes, it should be on the fore and aft centreline of the ship.
Yes, it should be away from all electrical power cables.
Yes, it should be sited on a non-metallic base if possible.
Why should Ground Stabilised True Motion display mode be avoided when using the ARPA for anti-collision purposes?
The true vector can never give an indication of collision risk with another ship.
The collision regulations are based on ship courses through the water.
The Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
