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.
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 dead slow ahead on the engines and leave the rudder in the hard over position.
Give the engines a short kick ahead.
Give half astern on the engines as this will increase the rate of turn.
Give full astern on the engines until ship has stopped and then full ahead on the engines with rudder hard over.

One prolonged blast (flash), followed by five or more short and rapid blasts (flashes).
Three short and rapid blasts (flashes).
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?

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.
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.

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.

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.

Only the electrical fuses for the scanner motor needs to be removed.
A sign needs to be attached to all the radars warning the bridge officers of repairs and the fact the radars are “Not to be used”.

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. However, to be sure of a safe passing distance, I will reduce my speed to allow the other vessel to pass ahead.

It will be only the wind speed that will determine the required number of tugs and how they are used.
The Port Authority will dictate the tug requirements and their use within the port limits.

The GPS display flashes and sounds an alarm.
The GPS display is always very accurate and does not give any indication of lack of accuracy.
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.
The true vector can never give an indication of collision risk with another ship.
True motion does not provide the collision risk of other ships.
The Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
