Quintupled.
What is the reason for the effect we call squat?
Increased velocity and decreased water pressure around the ship’s hull.
Decreased velocity and increased water pressure around the ship’s hull.
Increased effect of gravity due to closeness of the sea bed.
The bow and stern wave make the ship sink lower in the water.
You are about to pass another ship in a close situation. What can happen in this situation?
Due to suction, the two ships will be sucked together.
Your ship will not be affected in this situation.
The two ships will be pushed toward the banks.
The bow of your ship will be sucked towards the stern of the other ship.
How do you consider the indicated speed for berthing?
Too fast.
It is up to the pilot to decide.
To be sufficient.
Too slow.
You are to release the towing wire with forerunner. You have 3 men with you to do the work. How do you do it in a safe way?
Use the winch. Forerunner and wire stopper to pick up the slack and stop the wire. One man operating each. Make the forerunner fast on the bit, releasing the eye of wire and the stopper, lower the wire easy by forerunner.
After heaving on the wire by a forerunner, cut the forerunner and so let the wire free.
With manpower. Two men picking up slack and one man lifts off the eye and let go simultaneously.
How can you minimize the squat effect?
Decrease the speed as much as practicable.
Maintain your course and speed.
Do a zig-zag manoeuvre to reduce speed.
Increase speed if the ship is not already on full ahead.
What can be used to reduce the effect of the state of sea-waves?
Vegetable/fish oil.
Foam.
Fuel oil.
Crude oil.
In the shown situation, the bow of your ship is pushed away from the bank. How can you handle this?
Give starboard rudder in order to balance the force of the bank effect and rudder effect.
Put your engine full astern to stop your ship.
Give hard port rudder to get the ship back in the middle of the channel.
Do nothing as the ship will handle itself.
You are underway on a power driven vessel in open water, when you see another power driven vessel approximately five miles straight ahead on an opposite course. What action do you take?
Make a bold alternation to starboard and pass on his port side.
Make a bold alteration to port and pass on his starboard side.
Stand on with caution as he will alter course.
Try and call him on the VHF to decide on what action to take.
What is part number 1 called?

The setting tank.
The drainage tank.
What is item No. 9 shown in the diagram, fitted between evaporator and condenser of the fresh water generator?
A water deflector.
A water filter assembly.
A heating cap.
A desalinator unit.
The diagram shows loadline marks. How is the distance between S and T calculated?
One forty eighth of the summer draft.
One sixtieth of the summer draft.
Nine tenths of the FWA.
Four fifths of the FWA.
What do the intersecting horizontal lines signify in the diagram?
They show the actual angle of trim.
The change of draft after trimming.
The change in the centre of floatation, after trimming.
They only serve as a base for the two vertical lines.
Unconscious casualties who are brething and whose hearts are beating should be placed in the recovery position. What is the recovery position?
As shown in figure 1.
As shown in figure 2.
As shown in figure 3.
As shown in figure 4.
