Keep as far as possible on the starboard side of the channel and maintain speed to retain effective steerage.
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 the OOW is busy with the safe navigation of the ship he should have exhibited the “Not under Command” signals and made other ships keep clear.
If risk of Collision existed, the fishing boat should have contacted the larger ship over the VHF before the collision took place.

Check that the deviation will not lead into danger.
Inform the Master.
Is the location of a vessel’s standard compass binnacle critical?
Yes, it should be away from major electrical power cables.
Yes, it should be on the fore and aft centreline of the ship.
Yes, for the reasons stated in all of the suggested answers.
Yes, it should be sited on a non-metallic base if possible.
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.

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.
According to rule 12 of the International Regulations for Preventing Collisions, in the situation illustrated, which sailing vessel (A or B) must keep out of the way of the other?
Sailing vessel B must out of the way of sailing vessel A.
Sailing vessel A must out of the way of sailing vessel B.

This vessel is not under command and stopped in the water.
This vessel is aground.
This is a vessel constrained by her draft.
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.
Can anything be done on a vessel with forward speed, to reduce the change in heading caused by a right hand fixed pitch propeller being put astern?
Yes, the rudder can be put to port.
No, 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 cycled from side to side.
The rudder should be put hard to starboard to reduce the water flow to the left side of the propeller.
The ship’s rudder is full over when the ship’s engines are full ahead. Will the turning effect (lift force) of the rudder be changed when the engine is stopped?
No, the lift force is unaffected by the speed of the propeller.
Yes, the lift force will be dramatically reduced when the engines are stopped.
Yes, the lift or turning force will be reduced to about 50 % of the original lift force when the engines are stopped.
No, the turning force applied by the rudder will be maintained within about 90 % of the lift force when going full ahead.

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?
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.
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.
Two mooring lines are pretensioned equally and have the same length, same breaking strength and same directional load. However, one is made of wire (with a full load elastic elongation of about 1,5 % of its length) and the other made of nylon (with a full load elongation of about 30 % of its length). If a gust of wind increases the load on the lines, how will it be shared?
Wire takes 45 % of the extra load. Rope takes 55 % of the extra load.
Wire takes 55 % of the extra load. Rope takes 45 % of the extra load.
The wire and rope will share the load equally.
Wire takes 95 % of the extra load. Rope takes 5 % of the extra load..

No need for reporting as the order was given from the bridge.
Report all clear to the tug.
Report all clear to the Engine Room.
How will the ship behave if it experiences a complete loss of power (black out) in the situation illustrated?
The wind will push the vessel sideways, but the heading will not change.
The vessel will gradually swing to port and the speed will slowly reduce.
The vessel will continue on course and the speed will slowly reduce.
The vessel will gradually swing to starboard and the speed will slowly reduce.
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.
If your vessel is fitted with wires on self-stowing “split drum” winches, the advantage of having these split drum winches is:
