You are in an area of restricted visibility, close to a port. You hear this signal. What vessel does it come from and what additional information does the signal provide?
A vessel at anchor, more than 100 metres in length. The additional signal indicates that her cable extends at least 25 metres from her bow.
A vessel at anchor, more than 100 metres in length. She is sounding the additional signal to give warning of her position.
A vessel aground, more than 100 metres in length. The additional signal indicates which side the clear water lies on.
A vessel at anchor, less than 100 metres in length. She is sounding the additional signal top give warning of her position.
Which option best completes the following statement? An operator using ECDIS, will notice an out of position navigation buoy because:
A local port authority would send an automatic signal to ECDIS.
It is coloured orange on an ECDIS display.
The radar return and ENC buoy symbol will not coincide.
There will be a flashing alarm on ECDIS showing which one is out.
What is the correct understanding of the term “a ship with good Directional Stability”?
A ship which when the rudder is left amidships, it will continue on approximately a straight course.
A ship where the amount of positive transverse stability (GM) will vary with the direction of the ship’s head.
A ship which when a rudder angle is applied and the ship starts to swing, will continue to swing even after the rudder is returned to amidships.
A ship which will maintain its course unless large rudder angles are applied.
What is correct UTC in this example? Approx. Pos: N49° 51′ W35° 23′, zone +2, Local Time 0900.
23 00.
07 00.
19 00.
11 00.
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.
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.
When should voyage planning be done?
During the pilotage when leaving the berth.
Prior to leaving the berth.
Before the vessel completes the previous passage.
Before the pilot is leaves the vessel at the departure port.
What are the limits of a passage or voyage plan?
From pilot to pilot.
From berth to berth.
It is dependant on the voyage and if there are any river or canal transits.
From Full Away On Passage (FAOP) to End Of Passage (EOP).
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.
When navigating along a coastline what should be considered the most accurate method of navigating?
Passing close to navigational buoys.
Use of radar ranges and bearings.
Bearings of navigational shore marks such as lighthouses.
Use of Differential GPS.
If a ship requires 2 nautical miles to stop in the water from a “crash stop” when proceeding at full ahead in deep water. What will the stopping distance be in shallow water?

A shorter distance.
What is the depth of an iceberg below the surface of the sea?
The draught of an iceberg is normally about 3/4 of its total depth.

The draught of an iceberg is about the same as the visible part of the iceberg above the water.
The depth of an iceberg below the surface is always about one sixth of its total depth.

When coming up with another vessel from a direction more than 22,5° abaft her beam.

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 Ground Stabilised True Motion display mode be avoided when using the ARPA for anti-collision purposes?

Similar distance to deep water.
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.

No, the rudder is most effective at angles between 10 and 20°.
No, the rudder is most effective at small rudder angles.
No, the most effective rudder angle is about 25 to 30°, this is because the rudder is stalling at 35° angle.
Yes, the rudder is most effective at max angle.
The ship’s engine is going astern and the ship is piking up sternway. The rudder is amidships and the ship has a single, right-handed, fixed pitch propeller. What would be expected to happen?
The ship will move astern at an increasing speed and the stern start to swing off to starboard.
The ship will probably start to change heading to port and stern speed will increase.
The ship will probably go straight astern without a change in heading and the stern speed will increase.
The ship will probably start to change heading to starboard and stern speed will increase.

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?
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.
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 consider him incapable of taking over the responsibility of the watch and that he should retire to his cabin and sleep it off.

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.
