- Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Navigation, NA – Management Level». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Navigation, NA – Management Level» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test examines candidates’ mastery of navigation theory and practice for a wide range of maritime vessels. It includes multiple-choice questions on topics such as collision avoidance, voyage planning and electronic chart systems. Practical scenarios assess the ability to apply international maritime regulations in real-world situations. Candidates must demonstrate proficiency in using radar, ARPA and ECDIS for safe navigation. The test also covers emergency procedures, including ship handling in adverse weather conditions. A key component focuses on bridge resource management and effective decision-making under pressure. Questions on meteorology and oceanography ensure understanding of environmental factors affecting navigation. Successful completion of the test confirms readiness for managerial-level responsibilities in the maritime industry.

You are a Senior Officer of the Watch on vessel “A” and are passing through the Straits of Gibraltar. The vessel’s speed is 18 knots and your vessel is overtaking several other vessels, when the visibility reduces down to about 2 nm. What aspects would you consider when establishing a “safe speed” for your vessel?
Deciding safe speed consider: 2 miles visibility; traffic density; manoeuvrability of vessel; effectiveness of navigational equipment (ARPA etc); state of sea and currents and navigational hazards.
A safe speed is where a vessel can take proper and effective action to avoid collision and be stopped within an appropriate distance.
Safe speed depends only on the vessel’s engine power and size.
Safe speed is always fixed at 10 knots regardless of conditions.

Which of the options best describes how a “Balanced Rudder” is constructed?
There is equal rudder area forward and aft of the turning axis, the turning axis being at the geometrical centre of the rudder area.
The rudder is positioned entirely behind the turning axis to increase control.

A vessel may proceed only when it has received specific orders to do so.
A vessel may proceed only when it has received specific orders to do so, except that vessels which can safely navigate outside the main channel need not comply with this message.
Vessels must stop and wait for pilot boarding before proceeding.

The bridge wheelman has not reported for duty and there is a suspected “Man Overboard” situation on your vessel. The ship has been searched and there is one seaman missing? The vessel turns round and retraces the course back, calling for assistance from other vessels in the vicinity. What should be the focal point for any search pattern to be established?

Concentrate search efforts equally in all directions from the current vessel position.
Determine when the seaman was last sighted and concentrate the search round the course line between the last sighting and present position, taking into account any prevailing current.
Wait for instructions from the coast guard before starting the search.
