Land is stopped with the vessel symbol moving across the sea floor.
What are the main advantages to the Navstar, Glonas and Galileo satellite navigation systems?
These satellite systems give world-wide coverage 24 hours a day.
Satellite navigation systems also give information about weather and wave conditions.
If a vessel uses any one of them, there is no need to practice other forms of navigation.
They are all made specifically for ships and marine operations.
You are in an area of restricted visibility. You hear this sound signal. What does it mean?
That there is a vessel aground in the vicinity.
That there is a vessel at anchor in the vicinity.
That there is a vessel engaged in underwater operations in the vicinity. She has divers down.
That there is a vessel in distress nearby.
This vessel is encountered at the mouth of a river. According to the International Regulations for Preventing Collisions and the illustrated shapes, what type of vessel is it?
This is a vessel engaged in dredging or underwater operations. The two balls in a vertical line indicate the side on which it is safe to pass; the two diamonds in a vertical line indicate the side on which an obstruction exists; the ball/diamond/ball indicate that the vessel is restricted in her ability to manoeuvre.
This is a vessel engaged in dredging or underwater operations. The two balls in a vertical line indicate the side on which an obstruction exists; the two diamonds in a vertical line indicate the side on which it is safe to pass; the ball/diamond/ ball in a vertical line indicate that the vessel is restricted in her ability to manoeuvre.
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?
I am about to depart the berth.
Caution! I have an anchor down.
You should proceed at slow speed when passing me.
My engine is disabled.
In a canal without water flow, if a vessel was approaching a bank at an angle, what would be the probable effect on it?
The vessel’s stern is pushed away from the bank.
The vessel’s bow is attracted by the bank.
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.
You are on a power-driven vessel underway in open water. You sight these lights on the port bow, on a steady bearing. The distance is closing. What are you looking at and what action will you take in compliance with the International Regulations for Preventing Collision at Sea?
This is a power-driven vessel, more than 50 metres in length or less than 50 metres in length and showing a second masthead light, restricted in her ability to manoeuvre. The sidelight of a second vessel can be seen beyond her. Under rule 18, I am obliged to keep clear of the first vessel and will therefore take appropriate avoiding action.
This is a power-driven vessel engaged in towing, less than 50 metres in length, length of tow under 200 metres and the tow, both being restricted in their ability to manoeuvre, seen from the starboard side. Under rule 18, I am required to keep clear and will take appropriate avoiding action.
Once a ship (equipped with self-stowing auto-tension winches) is moored alongside a loading or discharging berth, how is it recommended that the winches are set?
All mooring winches be left in “auto-tension” mode.
All winches to be left with the manual brake on and out of gear.
The “breastline” and “headline” winches be left in the auto-tension mode and spring winches with manual brake on.
The “spring” winches be left in the auto-tension mode and all other winches with the manual brake on.
In an extreme case, in addition to having your winch brakes as tight as can be, you can increase the brake holding capacity of the winch drum by putting it in gear and setting the power to the “heave” position. However this may cause:
All the listed alternatives.
The increased braking power of the winch to exceed the breaking strength of the wire and rope paid out from it which might cause the wire or rope to part.
Strain on the fairleads and rollers in use in excess of their Safe Working Load.
Damage to the winch by distorting the shaft.
Which of the four figures illustrated shows the correct position line for the following situation: Latitude 50° 00′ N, Longitude 30° 00′ W, Time 1200 GMT. Course steered: 090° True, Speed: 12 knots, bearing of the sun: 200°, Intercept correction: 00° 02′ Towards (observed altitude – computed altitude).
Figure 2 is correct.
Figure 4 is correct.
Figure 3 is correct.
Figure 1 is correct.
What type of vessel is this and from what direction are you seeing it?
This is a vessel engaged in fishing other than trawling, making way through the water, with outlying gear extending more than 150 m in the direction of the all-round red light. I am seeing her from astern.
This is a vessel engaged in pilotage operations, deploying or recovering a pilot. I am looking at her port side.
This is a vessel engaged in fishing other than trawling, making way through the water, with outlying gear extending more than 150 m in the direction of the all-round white light. I am looking at her port side.
This is a vessel engaged in pilotage duties at anchor. I am looking at her port side.
If your vessel is fitted with wires on self-stowing “split drum” winches, the advantage of having these split drum winches is:
Increased brake holding capacity due to the ability to keep the paid out wire in a single layer on the drum.
Less chance of the wire being jammed in the reel.
No crushing of the wire.
All the listed alternatives.
With a pilot ladder, the lowest spreader shall be the 5th step from the bottom. At what interval should there be further spreaders upwards on the ladder?

The Fore and aft Centreline is indicated by A, in the figure.
The ship’s rudder is full over when the ship’s engines are full ahead. Will the turning effect (lift force) of the rudder be changed when the engine is stopped?
Yes, the lift or turning force will be reduced to about 50 % of the original lift force when the engines are stopped.
Yes, the lift force will be dramatically reduced when the engines are stopped.
No, the lift force is unaffected by the speed of the propeller.
No, the turning force applied by the rudder will be maintained within about 90 % of the lift force when going full ahead.

Call the Master and advise him of the situation.
Display the NUC signal and consider stopping the engines.
All of the suggested answers.
Request the engine room to check the steering gear.
What action should the Officer of the Watch (OOW) take if he is forced to make a major deviation from the voyage plan?
There is no special action necessary.
Inform the Master.
Check that the deviation will not lead into danger.
Make an appropriate entry in the Log Book.
Who is responsible for the number and the position of any tugs to be used during a mooring operation?
The Master, with consideration of the advice of the pilot.
The Pilot is fully responsible for the number and use of tugs within the port area.
It will be only the wind speed that will determine the required number of tugs and how they are used.
The Port Authority will dictate the tug requirements and their use within the port limits.
Where can a ship expect an act of piracy to take place?
All over the world.
At the south end of the Red Sea.

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.
Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.
The only effective method is by using the bow thruster to push the bow to starboard.
Astern on the engines will allow Transverse Thrust to continue the swing.
By applying the rudder hard over to starboard and going ahead on the engines.

That there is another vessel nearby, but that she is at anchor.
That there are two more vessels nearby.
That there is another vessel in the vicinity and that she has just altered course to port.
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.
True motion does not provide the collision risk of other ships.
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.
Why should a Ground Stabilised True Motion radar display not be used for anti-collision purposes?
Because this display is only ever used for navigation.
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.
True motion does not provide the collision risk of targets as only true vectors are available.
The Master arrives on the bridge obviously under the influence of alcohol and states he is taking over the “con” of the ship. What actions should the Officer of the Watch (OOW) take in this situation?
Attempt to diplomatically avoid taking any actions that would put the ship or crew into danger and call the Chief Officer for assistance.
Tell the Master you do not think this is a good idea and retain control of the watch.
Tell the Master you consider him incapable of taking over the responsibility of the watch and that he should retire to his cabin and sleep it off.
Watch the actions made by the Master and if not dangerous, wait until the Master becomes more capable to take control or leaves the bridge.
What special equipment can often provide assistance in locating a survival craft or man overboard and in the water?
A SART.
A sectored search pattern.
A RACON.
AIS.

Bearing and distance from a navigational Buoy.
Compass bearings of three shore objects.
Bearing using the Radio Direction Finding of three radio beacons.
The Master has decided to “single up” to a spring line at each end as the last lines to let go whilst unmooring. Which of the following methods should be used to hold the lines, whilst waiting for the order to “let go”?
The eye of the lines should be put on the bitts, fig. 2.
The line should be turned up on the bitts, fig. 1.
The line should be held on a stopper ready for immediate release, fig. 4.

The same as deep water.
Slower than deep water.
Faster than deep water.
It would be very difficult to maintain full deep sea RPM on the engines and therefore difficult to assess the speed.
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.
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?
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.
Increase speed slightly to pass each other as quickly as possible and thereby reduce the effects of “ship to ship” interaction.
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.
A tug is moving towards the bow of the ship to make fast and is in the vicinity of the ship’s shoulder, as illustrated. What specific danger should be considered when making this approach to the bow?
The positive pressure field at the ships bow may repel the tug and make the connection very difficult to establish.
The tug may be turned across the bow of the ship and also suffer a lose of stability with a danger of being turned over if touched by the ship.
The stern of the tug may be sucked in towards the bow and also suffer a reduction in the positive GM, making it very unstable.
All of the alternative answers.
What are the required data inputs into most gyro compasses to reduce any possible compass error?
All of the data in the suggested answers.
Latitude and Speed.
Maximum helm angle and rolling period.
Deviation and Variation.
Can the OOW be the sole lookout?
Only if the ARPA radar is set onto Auto Acquisition with an audio alarm sounding when a ship is detected.
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.

This vessel is aground.
This vessel is not under command and stopped in the water.
This is a vessel constrained by her draft.
This vessel is not under command, but is making way through the water.
When the temperature of the air increases with height it is known as a “Temperature Inversion” and may influence the performance of some instruments on the ship. What should the bridge Officer of the Watch be prepared to happen?
The radar will be show abnormal sea clutter as the pulse is trapped by the inversion.
The GPS may give errors of position because of interference of incoming signals from the satellites.
Abnormal ranges of VHF RT and Second Trace Returns on the radar.
The bearings obtained from the Directional Finder (DF) will not be as accurate as normal.
What is the advantages of a GPS satellite system compared to other navigational aids?

How can an ARPA assist the ship to steer a suitable course to make good the entrance to a channel?
Select Relative motion display and make Own Ship vector pass through the middle of the entrance to the channel.
Acquire the buoy at the entrance to the channel and on relative vector display alter course to make the vector of the buoy pass directly through the centre of the screen.
Select True ground stabilised vectors and make the vectors from both buoys at the entrance to the channel pass either side of the centre of the screen.
Select ground stabilised true motion display and alter course so that own ships true vector passes through the middle of the entrance to the channel.
What immediate actions should the Officer of the Watch take when the ship goes aground on an uncharted shoal in the middle of the ocean?
Stop engines and immediately request “Full Astern”.
Stop engines and tell the engine room to switch over to high suctions.
Stop engines and call the Master.
Sound the General Alarm and plot the ships position.
You are approaching the port entrance. What do these lights mean?

Vessels may proceed – two-way traffic.
A vessel may proceed only when she has received specific orders to do so.
A vessel may proceed only when she has received specific orders to do so, except that vessels which can safely navigate outside the main channel need not comply with this message.
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?
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.
Under the Rules a proper lookout should be maintained at all times and by all available means.
What does this flag mean?
