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 attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.
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.
As they approach, rudder should be applied quickly to avoid sheering into the path of each other. Then as they are alongside they will be attracted and finally repel each other as they pass clear.
There will be very little effect between the two ships as they pass.

The ship is required to be stopped in the water as quickly as possible, but without major changes to the ship’s heading. What is the most effective method to achieve this?
Make a zig zag manoeuvre while reducing the engine power.
Make a complete turn while reducing the engine power.
The use of the rudder hard over both sides combined with reducing engine power, a method known as “high frequency rudder cycling”.
Put the engine full astern and keep the rudder amidships.
In an extreme case, in addition to having your winch brakes as tight as can be, you can increase the brake holding capacity of the winch drum by putting it in gear and setting the power to the “heave” position. However this may cause:
Strain on the fairleads and rollers in use in excess of their Safe Working Load.
All the listed alternatives.
The increased braking power of the winch to exceed the breaking strength of the wire and rope paid out from it which might cause the wire or rope to part.
Damage to the winch by distorting the shaft.
When should voyage planning be done?
During the pilotage when leaving the berth.
Prior to leaving the berth.
Before the vessel completes the previous passage.
Before the pilot is leaves the vessel at the departure port.
How can the effects of Squat be minimized, when a ship is proceeding in shallow water?
Maintain a speed of about 6 knots and use minimal rudder when manoeuvring.
Enter the shallow water with a stern trim and proceed at a moderate speed.
Maintain a slow speed just sufficient to maintain steerage.
Decrease the speed and keep this ship to the centre of the channel where the water is probably deepest.
The ship’s engine is going astern and the ship is piking up sternway. The rudder is amidships and the ship has a single, right-handed, fixed pitch propeller. What would be expected to happen?
The ship will move astern at an increasing speed and the stern start to swing off to starboard.
The ship will probably start to change heading to port and stern speed will increase.
The ship will probably go straight astern without a change in heading and the stern speed will increase.
The ship will probably start to change heading to starboard and stern speed will increase.
If your vessel is fitted with wires on self-stowing “split drum” winches, the advantage of having these split drum winches is:
No crushing of the wire.
Increased brake holding capacity due to the ability to keep the paid out wire in a single layer on the drum.
Less chance of the wire being jammed in the reel.
All the listed alternatives.
In a canal without water flow, if a vessel was approaching a bank at an angle, what would be the probable effect on it?

What is the correct understanding of the term “a ship with good Directional Stability”?
A ship which when the rudder is left amidships, it will continue on approximately a straight course.
A ship where the amount of positive transverse stability (GM) will vary with the direction of the ship’s head.
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.
A ship which will maintain its course unless large rudder angles are applied.
The «Navigation (NA) Operational Level» subject covers both theoretical and practical knowledge regarding safety when working with electrical equipment. Mastery of this information is a key indicator of an employee's competence in their specific role on a vessel. As a 3rd officer responsible for navigation duties, your primary tasks include assisting senior officers in planning the ship’s voyage by calculating safe passage routes, preparing navigation charts, and monitoring weather conditions. You are also responsible for conducting regular safety checks on all life-saving equipment to ensure it is in good working order, as well as operating and maintaining navigational equipment like radar, GPS, and compasses to ensure they are functioning correctly.
