If your vessel is constructed with superstructure mostly forward. What is your analysis in which direction she will recline relative to the wind when drifting with no way on?

She will recline with the wind from abaft the beam

You are a twin screw vessel with the rudders amidships and both screw are going ahead. Can you identify the movement if the starboard screw is stopped

The bow will swing to starboard

A single-screw vessel with right-handed propeller is docking on her portside. What will happen if half astern engine and rudder amidship orders are applied?

What conclusion can you draw from the following statement, if your ship is making sternway of about 1.5 knots, and with rudder hard to starboard. Will this rudder position have any effect on the ship's behaviour?What conclusion can you draw from the following statement, if your ship is making sternway of about 1.5 knots, and with rudder hard to starboard. Will this rudder position have any effect on the ship's behaviour?

Yes, it will give the stern a lift force to starboard.

You are proceeding to a distress site and expect large number of people in the water. What is the best way to do for the recovery of survivors?

An inlatable liferaft secured alongside can be an effective boarding station for transfer of survivors from boats.

What is you analysis to the action you should execute if you are stationary right handed fix propeller that is experiencing a steady breeze on the port quarter and can temporarily hold on that position. ?

Going slow astern

What is your analysis on how much vessel draft increase is caused by the squat effect of a large vessel traveling at high speed?

in excess of two meters by mean.

What is the amount of chain you should release when using a single anchor in a bad weather situation?

10 times the depth of water

Your ship is equipped with a single right-handed fixed propeller. While steaming full ahead you reverse the engine to stop the ship. Can you identify from the following how will the ship react?

You will sheer to starboard and gradually lose headway.

How can you classify from the following statement is a non conformance of the Race Track turn procedures?

When about quarter of mile to the way around, back the inboard engine half ahead or full.

What is the primary responsibility of the duty watch officer when the pilot is maneuvering the vessel to dock?

Ensure that helm and engine orders given by the pilot are correctly executed.

What do you think is your immediate action as an officer on watch upon hearing the expressions, "man overboard starboard side"?

Give hard starboard rudder

To recover a man overboard in a racetrack turn. How many degrees from the original heading the vessel will steadied for the SECOND time after the turn?

360°

Can you identify from the following the most commonly used manoeuvre onboard ships in the event of a person overboard?

Williamson Turn

When the ship is approaching a steep bank, the effect known as "bank suction" acts, which of the following ways on a single-screw vessel proceeding along that channel?

It pulls the stern towards the bank.

What would be the result on the holding power if you shorten the anchor cable scope, ?

It will be reduced

You are the duty officer on the bridge, and a person is reported missing. Which of the following actions is to be considered as the appropriate maneuver in this situation?

Scharnow Turn

Can you identify which method of man overboard search if an individual falls overboard during periods of darkness and the exact time of the incident is unknown?

Williamson Turn maneuver

What conclusion can you make to maintain steerage in a following sea?

To steam at half the speed of the swells

If there is no wind and current, assuming your ship is going full ahead as you start to slow down, how would you identify the location of the pivot point?

It will move aft as the ship slows down.

Can you identify from the following man overboard maneuver with a disadvantage that is unintended for single propeller ship?

The Anderson Turn maneuver

You suspect that a crewmember has fallen overboard during the night and immediately execute a Williamson turn. What conclusion can you captivate on the primary advantage of the maneuver under these circumstances?

You will be on a reciprocal course and nearly on the track line run during the night

What would be your action to minimize the squat effect?

Decrease the speed as much as practicable

Can you identify which of the following is the equivalent of one shot of anchor cable?

15 fathoms

It is the effect being experienced by a vessel in a confined channel since the velocity of the water flow increases due to further restriction.

Squatting

How would Scharnow Turn be executed?

The rudder is put hard over and the initial turn is maintained until about 240° from the original course.

Can you identify on the following the equivalent of two shots of anchor cable?

54.87 meters

Can you identify which of the following statement the man over board execution of Williamson turn is TRUE? I. This is the most commonly used manoeuvre on board ships in the event of a person overboard II. Put the rudder hard over towards the side from which the man went overboard, to reduce the chances of the vessel's propeller striking the MOB III. After deviation from the original course by 60° , the rudder is put har over to the opposite side IV. Speed should be maintained during the turn as any changes in speed may bring the ship on a reciprocal course in a different position than the line of the initial course.

I,II,III, and IV is true

What evidence can you find about a ship when her course is unstable?

When you apply rudder, she will continue to turn long after the rudder is returned to amidships.

What should be done to return to your original course if a wave has overtaken your vessel and threw the stern to starboard?

Apply more starboard rudder
