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.
Select Relative motion display and make Own Ship vector pass through the middle of the entrance to the channel.
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.
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.
The ship is navigating in dense fog where the visibility is less than one mile. The Arpa radar is set on a range 12 miles on a course of 314° and own ship has a vector as shown. What is the vector mode selected on the Arpa?
True vectors.
Relative vectors.
Relative vectors, sea stabilised.
Relative vectors, ground stabilised.
Who is ultimately responsible for the voyage plan?

The Officer of the Watch (OOW) on duty.
The Second Officer as the official Navigation officer.
The ship owner will provide overall parameters within which the ship must follow.
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.
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.
There will be very little effect between the two ships as they pass.
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?
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.
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.
Why should Ground Stabilised True Motion display mode be avoided when using the ARPA for anti-collision purposes?
The collision regulations are based on ship courses through the water.
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 Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
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.
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.
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.
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.
What action should the Officer of the Watch (OOW) take if he is forced to make a major deviation from the voyage plan?
Inform the Master.
Make an appropriate entry in the Log Book.
There is no special action necessary.
Check that the deviation will not lead into danger.
When fastening synthetic fibre ropes such as polypropylene on bitts, for safety and better rope control it is recommended to:
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.
Make it fast with round turns on the leading bitt alone, fig. 1.
Make it fast in a figure of eight fashion, fig. 3.
When plotting a position, where should the Officer of the Watch select as the ships position, when three gyro compass bearings intercept as a triangle (Cocked Hat) and not as a single point?
At the point nearest to the danger, if any.
At the point nearest the course line drawn on the chart.
At the point furthest away from any danger.
At the centre of the triangle.
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?
A reduction in strength of 10 % to 15 %.
A reduction in strength of 30 % to 40 %.
A reduction in strength of 1 % to 5 %.
No reduction in strength.
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.
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.
Maintain speed and a straight course on the starboard side of the channel.
What are the main components causing the magnetic compass to require a regular evaluation and compass correction?
Permanent and induced magnetism in the ships structure.
The change in the position of the magnetic pole causing annual changes in the variation.

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 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.

What would be considered the most favourable heading of a ship when launching a lifeboat?
The ship should steer about 30° off the prevailing weather and sea with the boat to be launch on the leeside.
The ship should steer about 100° of the prevailing weather and sea with the boat to be launched on the leeside.
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 with the prevailing weather and sea on the beam and the boat to be launch on the leeside.
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 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.
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.
What is “AIR DRAUGHT”, in the figure?
Air draught is indicated by C, in the figure.
Air draught is indicated by A, in the figure.
Air draught is indicated by D, in the figure.
Air draught is indicated by B, in the figure.
What are the required data inputs into most gyro compasses to reduce any possible compass error?
Latitude and Speed.
Deviation and Variation.
Maximum helm angle and rolling period.
All of the data in the suggested answers.
Which of the following answers most suitably cover the standard duties of the bridge Officer of the Watch when the ship is at anchorage?
Display anchor signal, check the ships position and keep a good lookout.
Display the anchor signal, patrol the ship frequency and check the anchor chain for dragging.
Display anchor signal and keep a good lookout of other ships in the area.
Display the anchor signal and ensure the ship swings the same way at each change of tide.
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?
Abnormal ranges of VHF RT and Second Trace Returns on the radar.
The GPS may give errors of position because of interference of incoming signals from the satellites.
The bearings obtained from the Directional Finder (DF) will not be as accurate as normal.
The radar will be show abnormal sea clutter as the pulse is trapped by the inversion.
A balanced rudder has some of the rudder area forward of the rudder axis. About how much area should this be to call it a balanced rudder?
It should be about 20 %.
It should be about 5 %.
It should be about 55 %.
It should be about 50 %.
What are the immediate duties of the bridge Officer of the Watch when the ship suddenly runs into a fog bank?
Commence sounding the fog signal, engines on standby, call the Master and lookout, if not already on duty.
Commence sounding the fog signal and reduce speed to Slow Ahead.
Commence sounding the fog signal and call the Master and wait for him to arrive before taking any further actions.
Commence sounding the fog signal and if the radar indicates no echoes in the vicinity, proceed at the normal speed until ships are detected on the radar or until the fog lifts.
A ship is navigating in the Caribbean in August when it receives the warning of a Hurricane. To determine the centre of the storm the Master uses “Buys Ballot’s Law” and faces the wind. On what side of the Master would the low pressure area be located?
On the right side.
On the left side.
This is not a suitable method to use with a Hurricane.
Straight ahead.
