You are on a sailing vessel, underway in open water. This vessel is sighted on the starboard bow, on a steady bearing and the distance is closing. By the International Regulations for the Preventing Collisions at Sea, what action will you follow?
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I am required to keep out of the way. I will make a broad alteration of course to starboard.
By Rule 18, a power-driven vessel underway shall keep out of the way of a sailing vessel. I will maintain my course and speed, but will continue to monitor situation to ensure the other vessel takes avoiding action.
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I will maintain my course and speed.
This vessel is clearly a power-driven vessel and I anticipate that the bearing will therefore close and she will pass ahead at a safe distance.
A man is reported to have fallen overboard and the Officer of the Watch releases the lifebuoy and starts a man overboard manoeuvre, who are the first persons onboard he should inform?
The Master only.
The crew quarters for extra lookouts.
Master and Engine Room.
Chief Officer and lifeboat party.
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?
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.
The Second Officer, when on watch on the bridge, is often referred to as the OOW. What does OOW actually stand for?
Operator of the watch.
On official watch.
Officer of the Watch.
On official watchkeeping.
The ship is required to be stopped in the water as quickly as possible, but without major changes to the ship’s heading. What is the most effective method to achieve this?
Put the engine full astern and keep the rudder amidships.
The use of the rudder hard over both sides combined with reducing engine power, a method known as “high frequency rudder cycling”.
Make a complete turn while reducing the engine power.
Make a zig zag manoeuvre while reducing the engine power.
If the radar is set onto the Relative Motion Display, what would an echo of a target with no trail indicate? Note this the trail of the echo and not a vector.
The target is stopped and making no way through the water.
The target is on the same course and speed as own ship.
The target is on a constant bearing and getting closer to own ship.
The target is on a collision course with own ship.
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.
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.
What is the depth of an iceberg below the surface of the sea?
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 varies with the type of berg and its age.
The draught of an iceberg is normally about 3/4 of its total depth.
According to rule 13 of the International Regulations for Preventing Collisions at Sea, what is the definition of “an overtaking vessel”?
When coming up with another vessel from a direction more than 22,5° abaft her beam.
When the vessel is detected as a radar target or sighted visually in a position directly astern.
When coming up with another vessel from any direction abaft her beam.
When coming up with another vessel from a direction more than 45° abaft her beam.
Which of the answers best summarises the information which should be provided for the bridge Officer of the Watch within an effective Voyage plan?

Expected prevailing wind and weather.
Contingency arrangements in case of problems.
All of the suggested answers.
What does this signal hoist mean?
I require medical assistance.
Do you require assistance?
Stand by to assist me.
I require immediate assistance.
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 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 put from side to side in a “Rudder Cycling” movement.
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 put Hard to Port to reduce the water flow to the left side of the propeller.
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.

The vessel is steaming off the coast when the engine room informs the bridge it must stop engines immediately. Shortly afterwards they informed the bridge they would need a least three hours to fix it. Which of the following actions would be the most suitable taken by the bridge?
Display the NUC signal and keep a good lookout.
Display the NUC signal, maintain the watch and ask the Engine room to be a quick as possible.
Display the NUC signal, maintain the watch and wait for further developments.
Display the NUC signal, maintain the watch and determine how the ship is drifting and the probable position after 3 hours.
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 tension on both cables should be similar, to avoid one dragging and all the weight of the ship remaining on the other anchor only.
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.
What signal may be given by sound and by light to indicate that a vessel fails to understand the intentions or actions of another vessel, or is in doubt that sufficient action is being taken by the other to avoid collision?
Five prolonged blasts (flashes).
Five short and rapid blasts (flashes).
One prolonged blast (flash), followed by five or more short and rapid blasts (flashes).
Three short and rapid blasts (flashes).
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 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.
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.

By reference to the last entry in the Compass Error Log Book.
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.

Enter the shallow water with a stern trim and proceed at a moderate speed.
Maintain a slow speed just sufficient to maintain steerage.
Put a small forward trim on the vessel as this stops squat.
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.
Yes, the ship often steers better if trimmed by the stern.
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.
How will the ship behave if it experiences a complete loss of power (blackout) in the situation illustrated?
The vessel will gradually swing to port and the speed will slowly reduce.
The vessel will gradually swing to starboard and the speed will slowly reduce.
The vessel will continue on course and the speed will slowly reduce.
The wind will push the vessel sideways, but the heading will not change.
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.
The position of the ship is found by taking a series of bearings using a magnetic compass. How should an error of 5° WEST be applied to the compass bearings?
The error should be “High” or “Low” and therefore more information is required.
Add the 5° to the bearings.
Subtract 5° to the bearings.
The same error applies to all bearings and therefore it can be ignored.
What is important to check when transferring a position from the GPS output to a paper chart?
Any necessary corrections are applied to convert between the GPS datum and the chart datum.
Ensure that the chart has been corrected up to date.
Ensure that the GPS is setup on the same datum as the chart.
It is important to ensure that the GPS is setup on 2 dimensional and not 3 dimensional position fixes.

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.
According to the International Regulations for Preventing Collisions and the illustrated lights, what type of vessel is this and from what direction is it viewed?
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. Looking at its port side.
This is a vessel engaged in pilotage duties at anchor. Looking at its port side.
This is a vessel engaged in fishing other than trawling, making way through the water, with outlying gear extending more than 150 metres in the direction of the all-round red light. Looking at it from astern.
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.
What are the required data inputs into most gyro compasses to reduce any possible compass error?
All of the data in the suggested answers.
Maximum helm angle and rolling period.
Latitude and Speed.
Deviation and Variation.
You are on a power-driven vessel underway in open water. This vessel is sighted on the port bow on a steady bearing. What kind of vessel is it and what will your action be?
This is a sailing vessel not making way through the water. There is no risk of collision and I will maintain my course and speed.
This is a sailing vessel underway. I am the stand-on vessel and will maintain my course and speed under rule 17.
This is a vessel engaged in fishing. It is my responsibility to keep clear under rule 18 and I will alter course to starboard, sounding one short blast.
This is a sailing vessel underway, seen head-on. It is my responsibility to keep clear under rule 18 and I will take appropriate avoiding action.
If a distress signal is received on board your ship, what should be the first action that should be taken?
Determine how close your vessel is to the distressed vessel.
Contact SAR Authorities via nearest coastal Radio station.
Determine if anyone else has heard the distress signal and if your vessel is near the distress.
Attempt to establish contact with the distressed vessel.
What is understood by the term “Dew point” of the air?
All of the suggested answers.
The “Dew Point” is the point at the centre of an Anticyclone.
The temperature of the water vapour in a cloud.
The temperature at which water vapour in the air forms into water droplets.
When navigating along a coastline what should be considered the most accurate method of navigating?
Use of radar ranges and bearings.
Passing close to navigational buoys.
Use of Differential GPS.
Bearings of navigational shore marks such as lighthouses.
The «Navigation (NA) Operational Level» subject covers both theoretical and practical knowledge regarding safety when working with electrical equipment. Mastery of this information is a key indicator of an employee's competence in their specific role on a vessel. As a 3rd officer responsible for navigation duties, your primary tasks include assisting senior officers in planning the ship’s voyage by calculating safe passage routes, preparing navigation charts, and monitoring weather conditions. You are also responsible for conducting regular safety checks on all life-saving equipment to ensure it is in good working order, as well as operating and maintaining navigational equipment like radar, GPS, and compasses to ensure they are functioning correctly.
