In circumstances described in all of the answers provided.
When talking between ship and shore in a foreign land.
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.

Yes, for the reasons stated in all of the suggested answers.
Yes, it should be on the fore and aft centreline of the ship.
Yes, it should be away from all electrical power cables.

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.

Sound the General Alarm and plot the ships position.
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.
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.
True motion does not provide the collision risk of other ships.
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.
All of the alternative answers.
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.
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.

It does not matter where the spreaders are fitted.
At intervals not exceeding 15 steps.
You are on a power-driven vessel underway in open water. This vessel is sighted directly ahead. The distance is closing slowly. What action will you take under the International Collision Regulations and why?
The vessel is on a steady bearing and the distance is closing. I will therefore take avoiding action, altering course to starboard and sounding one short blast under rules 14 and 16.
I will maintain my course and speed. The other vessel is being overtaken and is therefore obliged to keep out of the way by rule 13.
I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.

About 1,5 nautical miles.
A shorter distance.
You are on a power-driven vessel underway in open water. This vessel is sighted wide on the port bow. It’s bearing is opening, but its distance is closing rapidly. Which of the following is a correct assessment of the situation and the action to be taken?
Risk of collision is deemed to exist and I will make a broad alteration of course to starboard, sounding one short blast. I will re-assess the situation when the alteration is carried out.
Risk of collision is deemed not to exist and I will maintain my course and speed. I will continue to monitor the situation.
Risk of collision is a possibility. I will maintain my course and speed for now, but be prepared for an alteration of course to port if the CPA seems to be less than 0,2 nm as we draw closer.
Risk of collision is deemed not to exist. However, to be sure of a safe passing distance, I will reduce my speed to allow the other vessel to pass ahead.
How can an ARPA assist the ship to steer a suitable course to make good the entrance to a channel?

The GPS system is based on hyperbola navigation.
The GPS system gives information about position, speed and time continuously world wide.
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.
Tell the Master you do not think this is a good idea and retain control of the watch.
What is important to check when transferring a position from the GPS output to a paper chart?
Ensure that the chart has been corrected up to date.
It is important to ensure that the GPS is setup on 2 dimensional and not 3 dimensional position fixes.
Ensure that the GPS is setup on the same datum as the chart.
Any necessary corrections are applied to convert between the GPS datum and the chart datum.
The maximum rudder angle on your ship is 35°. Do you think this is the angle that the rudder is most effective?
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.
