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.
Where can the size of the Magnetic Compass Error be found?
By taking the error from the Deviation Table on the bridge.
By taking a transit bearing of two fixed geographical positions and comparing it with the bearing of the same points on the chart.

The vessel’s stern is pushed away from the bank.
The vessel’s bow is attracted by the bank.
The vessel’s bow is pushed away from the bank.
The whole vessel would continue straight towards the bank and would require a large helm order to avoid going aground.
Why should a Ground Stabilised True Motion radar display not be used for anti-collision purposes?
Because this display is only ever used for navigation.
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.
True motion does not provide the collision risk of targets as only true vectors are available.

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.
What is the correct understanding of the term “a ship with good Directional Stability”?

A ship which when a rudder angle is applied and the ship starts to swing, will continue to swing even after the rudder is returned to amidships.

Strain on the fairleads and rollers in use in excess of their Safe Working Load.
Damage to the winch by distorting the shaft.

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.
No, the turning force is unaffected by the speed of the propeller.
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.
