As Chief Mate, what is your primary responsibility regarding the vessel's passage plan once it has been drafted by the Second Mate?

To review the plan for safety, efficiency, and compliance with company policy and international regulations, then present it to the Master for final approval. To execute the passage plan directly without further review, assuming the Second Mate's competence. To file the plan in the bridge logbook and prepare for departure.

Question 2

Your vessel is on a course of 090°T at 15 knots. At 0800 LT, a target is observed on radar at 045°T, 10.0 NM. At 0806 LT, the same target is at 040°T, 8.0 NM. Calculate the Closest Point of Approach (CPA) and Time to Closest Point of Approach (TCPA).

CPA 2.5 NM, TCPA 0818 LT CPA 3.2 NM, TCPA 0826 LT CPA 4.1 NM, TCPA 0835 LT CPA 1.8 NM, TCPA 0812 LT

Correct Answer:

CPA 3.2 NM, TCPA 0826 LT

Question 3

As Chief Mate, your vessel is en route from Tema to Rotterdam. Weather forecasts indicate a developing severe gale (Force 9) with high seas directly on your planned great circle route in 36 hours. What is the most appropriate management-level action to take?

Maintain the great circle route, as the vessel is designed to withstand severe weather. Alter course immediately to a rhumb line route, as it is generally safer in heavy weather. Consult with the Master, review alternative weather routing options, considering safety, cargo, crew, ETA, and fuel consumption, and recommend a revised passage plan. Reduce speed significantly and heave to, waiting for the gale to pass before proceeding.

Correct Answer:

Consult with the Master, review alternative weather routing options, considering safety, cargo, crew, ETA, and fuel consumption, and recommend a revised passage plan.

Question 4

During a celestial observation for meridian passage of a star, the following data was recorded: Sextant Altitude (Hs) = 45° 30.0' (North), Index Error (IE) = 2.0' off the arc, Height of Eye (HoE) = 16.0 meters. The star's Declination (Dec) was N 15° 20.0'. Calculate the observed latitude.

N 29° 16.0' N 59° 56.0' N 30° 04.0' N 44° 36.0'

Correct Answer:

N 29° 16.0'

Question 5

As Chief Mate, your vessel is navigating in a congested area using ECDIS as the primary means of navigation. Suddenly, the primary ECDIS unit fails completely, and the backup unit also becomes inoperable shortly after. What is your immediate management-level priority and subsequent course of action?

Immediately switch to paper charts for navigation and inform the Master, then continue the voyage. Inform the Master, activate the contingency plan, switch to the designated backup arrangements (e.g., paper charts or secondary independent system), ensure all relevant information is transferred, and assess the impact on the passage plan and watchkeeping arrangements. Attempt to troubleshoot both ECDIS units simultaneously while maintaining a visual lookout. Reduce speed to bare steerageway and anchor at the first available opportunity, regardless of traffic or depth.

Correct Answer:

Inform the Master, activate the contingency plan, switch to the designated backup arrangements (e.g., paper charts or secondary independent system), ensure all relevant information is transferred, and assess the impact on the passage plan and watchkeeping arrangements.
