A ship is equipped with a right-handed fixed pitch propeller, which when going from Full Ahead to Full Astern will make the ship sheer to starboard. Can anything be done to reduce this change in heading?
The rudder should be kept amidships when going astern and there is little that can be done to reduce the swing to starboard.
The rudder can be put from side to side in a “Rudder Cycling” movement.
The rudder can be put to Hard to Port to reduce the water from to the right side of the propeller.
The rudder should be put Hard to Port to reduce the water flow to the left side of the propeller.

You are in open water and clear conditions. You are approaching the pilot station when you hear this signal from a vessel ahead of you. What does it signify?
That the vessel is picking up his pilot.
That the vessel is altering his course to starboard.
That the vessel is starting his engine and resuming his passage.
That the vessel is operating astern propulsion.
How will the ship behave if it experiences a complete loss of power (black out) in the situation illustrated?
The wind will push the vessel sideways, but the heading will not change.
The vessel will gradually swing to port and the speed will slowly reduce.
The vessel will continue on course and the speed will slowly reduce.
The vessel will gradually swing to starboard and the speed will slowly reduce.
In a canal without water flow, if a vessel was approaching a bank at an angle, what would be the probable effect on it?
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.
What are the limits of a passage or voyage plan?
From berth to berth.
It is dependant on the voyage and if there are any river or canal transits.
From Full Away On Passage (FAOP) to End Of Passage (EOP).
From pilot to pilot.
What methods could be introduced into a passage plan for continuous monitoring of the ships position when navigating along a coastline?
Parallel Index lines.
Conspicuous headlands and navigational marks for taking positions.
The radar ranges of the coastline at all course alteration points.
All of the suggested answers.
Which option best completes the following statement? An operator using ECDIS, will notice an out of position navigation buoy because:
There will be a flashing alarm on ECDIS showing which one is out.
A local port authority would send an automatic signal to ECDIS.
The radar return and ENC buoy symbol will not coincide.
It is coloured orange on an ECDIS display.
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.
