You are in open water and clear conditions. You are approaching the pilot station when you hear this signal from a vessel ahead of you. What does it signify?
That the vessel is starting his engine and resuming his passage.
That the vessel is altering his course to starboard.
That the vessel is picking up his pilot.
That the vessel is operating astern propulsion.
Who is responsible for the number and the position of any tugs to be used during a mooring operation?
The Pilot is fully responsible for the number and use of tugs within the port area.
The Master, with consideration of the advice of the pilot.
The Port Authority will dictate the tug requirements and their use within the port limits.
It will be only the wind speed that will determine the required number of tugs and how they are used.
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.
This is not a suitable method to use with a Hurricane.
Straight ahead.
On the left side.
Who is ultimately responsible for approving the voyage plan?
The Officer of the Watch (OOW) on duty.
The Second Officer as the official Navigation Officer.
The Master.
The ship owner will provide overall parameters within which the ship must follow.
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.

1 = d, 2 = a, 3 = b and 4 = c.
1 = b, 2 = c, 3 = d and 4 = a.
1 = c, 2 = d, 3 = a and 4 = b.
1 = a, 2 = b, 3 = c and 4 = d.

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 bow is attracted by the bank.
The vessel’s bow is pushed away from the bank.
The vessel’s stern is pushed away from the bank.
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.
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.
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.

Yes, it should be sited on a non-metallic base if possible.
The rudder is in the hard over position with the propeller stopped and the ship turning slowly. On a ship with a single fixed pitch right handed propeller and no thrusters, what can be done to make the ship increase the speed of turn without significantly increasing the forward speed of the ship?
Give the engines a short kick ahead.
Give dead slow ahead on the engines and leave the rudder in the hard over position.
Give full astern on the engines until ship has stopped and then full ahead on the engines with rudder hard over.
Give half astern on the engines as this will increase the rate of turn.

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.

No, the turning force applied by the rudder will be maintained within about 90 % of the turning force when going full ahead.
Yes, the turning force will be reduced to about 50 % of the original force when the engine is stopped.
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.
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 30° off the prevailing weather and sea with the boat to be launch on the leeside.
Where can the size of the Magnetic Compass Error be found?
By reference to the last entry in the Compass Error Log Book.

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.
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.
