When the Master informs the Officer of the Watch that he is taking over the “con”.
The ship has a right-handed propeller and is swinging to starboard when the engines are slow ahead and the rudder is to starboard. The engines are stopped and the rate of swing rapidly slows down. How could the swing to starboard be maintained without the ship making much headway.
Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.

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.
The ship is drifting in the open sea with a temporary engine breakdown. The ship is equipped with GPS navigation equipment. What should the bridge Officer of the Watch do in this situation?

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 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.

I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.
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.

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.
True motion does not provide the collision risk of other ships.
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.
What is the correct understanding of the term “bank effect”? If a ship was approaching the bank at an angle, what would be the effect on the ship?

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.
Where would the “pivot point” be considered to be located when the ship is proceeding at full speed ahead and there is no wind or current?
At a position near the stern of the ship.
At amidships.
At about 1/6 of the ship’s length from the stern.
At about 1/6 of the ship’s length from the bow.
Rule 12 of the International Collision Regulations prescribes the action to be taken by a sailing vessel when meeting another sailing vessel.

The upwind sailing vessel must keep out of the way of the downwind sailing vessel.
Sailing vessel B must keep out of the way of sailing vessel A.
Both sailing vessels are required to take avoiding action.
Sailing vessel A must keep out of the way of sailing vessel B.
