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.
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?
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.
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.

Never should the Officer of the Watch be the only lookout.
During daylight when visibility and traffic allows.
The position of the ship is found by taking a series of bearings using a magnetic compass. How should an error of 5° WEST be applied to the compass bearings?
The error should be “High” or “Low” and therefore more information is required.

What is the correct understanding of the term “a ship with good Directional Stability”?
A ship moving forwards with the rudder amidships, will continue in a straight line.
The ship will shear away from its heading if not controlled.
A ship when swinging, will continue to swing even after the rudder is returned to amidships.
A ship will always follow in the direction that the rudder is put.
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.

A red light or a green light, with a minimum range, in a vessel of 50 metres or more, of 3 miles. In a vessel of 10 metres.
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.
If the radar is set onto the Relative Motion Display, what would an echo of a target with no trail indicate? Note this the trail of the echo and not a vector.
The target is stopped and making no way through the water.
The target is on the same course and speed as own ship.
The target is on a constant bearing and getting closer to own ship.
The target is on a collision course with own ship.
You are on a power-driven vessel underway in open water. You sight these lights on the port bow, on a steady bearing. The distance is closing. What are you looking at and what action will you take in compliance with the International Regulations for Preventing Collision at Sea?
This is a power-driven vessel, more than 50 metres in length or less than 50 metres in length and showing a second masthead light, restricted in her ability to manoeuvre. 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.

The GPS system has a built-in group of six radio-beacons called a Decca chain.
The GPS system is based on hyperbola navigation.
The gyro compass can suffer from a compass error and may need to be allowed for, when steering a course in a dangerous navigational area. What is the probable cause of the error?

Put the engine full astern and keep the rudder amidships.
The use of the rudder hard over both sides combined with reducing engine power, a method known as “high frequency rudder cycling”.
Make a complete turn while reducing the engine power.
Make a zig zag manoeuvre while reducing the engine power.
When making a new pilot ladder onboard the ship, which of the following ropes would be best suited as the side ropes on which the steps are fastened?
Nylon rope.
Polyester rope.
Polypropylene rope.
Uncovered manila rope.
With the Master on the bridge, when is the Officer of the Watch officially relieved of their responsibility for the vessel?
When the Master starts giving steering orders.
As soon as the Master enters the bridge.
It varies from deep sea to pilotage operations and is never very clear.
When the Master informs the Officer of the Watch that he is taking over the “con”.
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.
