1When planning an ECDIS passage, which mariner-set depth parameter defines the primary boundary between navigable and non-navigable water for look-ahead anti-grounding indications?

A.Safety Contour

B.Deep Contour

C.Shallow Contour

D.Safety Depth

Explanation: The Safety Contour is the primary boundary configured in ECDIS that delineates navigable water from non-navigable water. If the selected depth value does not match an available contour on the vector electronic navigational chart (ENC), ECDIS defaults to the next deeper available contour and generates visual and audible alarms if the vessel's look-ahead vector crosses it.

2A vessel observes a celestial body's sextant altitude (hs) as 48°14.2'. The index error of the sextant is 2.4' on the arc, and the height of eye is 16 meters above sea level (dip correction = 1.76 × √h = 7.0'). What is the apparent altitude (ha)?

A.48°23.6'

B.48°09.6'

C.48°04.8'

D.48°18.8'

Explanation: To obtain apparent altitude (ha) from sextant altitude (hs), apply index error (IE) and dip. Since index error is 'on the arc', it is subtractive (-2.4'). Dip is always subtractive (-7.0'). Therefore: ha = 48°14.2' - 2.4' - 7.0' = 48°04.8'.

3In terrestrial navigation, which condition renders a two-bearing position line fix from a single landmark (running fix with a transferred position line) least reliable?

A.Taking observations when the angle between the two bearings is exactly 90 degrees

B.A significant uncalculated tidal stream running perpendicular to the course steered between observations

C.Using a high-precision digital gyrocompass repeater with verified zero error

D.Maintaining a constant engine speed in calm water with no wind or current

Explanation: A transferred position line assumes that the vessel's exact ground track and distance run between the first and second observations are known precisely. A strong unpredicted beam current causes unknown leeway and drift, transferring the first line of position with a large positional displacement error.

4When navigating in the Adriatic Sea near the Croatian coast using GNSS, what geodetic datum is the standard reference for official Croatian Hydrographic Institute (HHI) electronic navigational charts (ENCs)?

A.Hermannskogel (Bessel 1841 ellipsoid)

B.ED 50 (European Datum 1950)

C.Pulkova 1942

D.WGS 84 (World Geodetic System 1984)

Explanation: Under IHO standards (S-57) and international practice followed by the Croatian Hydrographic Institute (Hrvatski hidrografski institut — HHI), all official ENCs must be referenced to the WGS 84 datum. Older legacy Croatian paper charts constructed on the Hermannskogel / Bessel datum require datum shift corrections when plotting GNSS coordinates.

5A vessel is following a great circle track across the North Atlantic from the English Channel to New York. How does the vessel's true course change along the great circle route?

A.The course remains strictly constant throughout the entire transoceanic passage.

B.The course changes continuously as the track crosses successive meridians, so the route may be approximated by a series of rhumb-line legs.

C.The course decreases at a constant rate of exactly 1 degree per 60 nautical miles run regardless of latitude.

D.The course alternates between true north and true south at every vertex.

Explanation: Except in special cases such as the equator or a meridian, a great-circle arc cuts successive meridians at different angles, so true course changes along the route. An approved passage plan may represent that curve with safe rhumb-line legs whose waypoint spacing is selected for the route, charting system, hazards, weather, and monitoring needs.

6What is the primary function of the Target Association feature in an integrated Radar/ARPA and AIS bridge display system?

A.To merge AIS and radar tracked targets into a single physical symbol when their position, course, and speed vectors match within pre-set criteria.

B.To automatically transmit synthetic distress alerts to nearby AIS-equipped vessels when an ARPA target is within 2 nautical miles.

C.To slave the autopilot heading directly to the moving track of the leading target vessel.

D.To convert raw radar reflections into high-resolution optical video imaging.

Explanation: Target Association (or target fusion) prevents bridge display clutter and operator confusion by combining an AIS report and an ARPA radar tracked target into a single unified symbol when position, course, and speed criteria agree within specified tolerances.

7A vessel drawing 11.4 meters static draft is transiting a shallow fairway at 14 knots where the water depth is 13.0 meters. The ship's block coefficient (Cb) is 0.80. Using the open water squat formula (Squat = Cb × V² / 100 in meters), what is the estimated squat and resulting dynamic under-keel clearance?

A.Squat is 0.96 m; dynamic UKC is 0.64 m.

B.Squat is 2.24 m; vessel is grounded by 0.64 m.

C.Squat is 0.45 m; dynamic UKC is 1.15 m.

D.Squat is 1.57 m; dynamic UKC is 0.03 m.

Explanation: Applying the open water squat formula: Squat = 0.80 × (14)² / 100 = 0.80 × 196 / 100 = 1.568 meters ≈ 1.57 m. Initial static clearance = 13.0 m - 11.4 m = 1.60 m. Dynamic UKC = 1.60 m - 1.57 m = 0.03 m. This illustrates a severe grounding hazard requiring immediate speed reduction.

8Under IMO Resolution A.893(21) on voyage planning, what are the four mandatory, sequential phases of passage planning that the Master must verify?

A.Assessment, Navigation, Routing, and Reporting

B.Charting, Briefing, Steaming, and Docking

C.Appraisal, Planning, Execution, and Monitoring

D.Inspection, Verification, Piloting, and Anchoring

Explanation: IMO Resolution A.893(21) 'Guidelines for Voyage Planning' defines four distinct and progressive phases: Appraisal (gathering all relevant nautical information), Planning (detailed berth-to-berth route creation), Execution (briefing the team and commencing passage), and Monitoring (continuous real-time position verification).

9When steering by magnetic compass, which permanent shipboard component is primarily responsible for causing Coefficient B deviation (semicircular deviation that changes with heading)?

A.Athwartships soft iron induced by the vertical component of the Earth's magnetic field

B.Symmetrical horizontal soft iron spheres (Flinders bar) mounted on the binnacle

C.Fore-and-aft permanent magnetic field of the ship's hard iron structure

D.Electromagnetic leakage from VHF bridge communications radios

Explanation: Coefficient B represents semicircular deviation proportional to the sine of the compass heading. It is caused primarily by the permanent longitudinal (fore-and-aft) magnetic component of the ship's hard iron hull, supplemented by induced magnetism in vertical soft iron (corrected by the Flinders bar).

10An ocean passage plan requires crossing an area where NAVAREA III navigational warnings report a decommissioned oil platform with unlit wreckage. Under SOLAS Chapter V Regulation 27, what is the Master's legal obligation regarding nautical charts and publications?

A.Only the harbor approach chart for the destination port requires updating prior to departure.

B.All charts, publications, and ENCs for the intended voyage must be fully corrected up to date using the latest Notices to Mariners and active radio navigational warnings.

C.Navigational warnings older than 30 days can be disregarded if ECDIS displays standard ENC depth contours.

D.The Master may rely entirely on commercial weather routing advice without manually updating shipboard charts.

Explanation: SOLAS V/27 mandates that nautical charts and nautical publications, such as sailing directions, lists of lights, notices to mariners, and tide tables for the intended voyage, must be adequate and up to date. The Master must ensure all active T&P (temporary and preliminary) notices and NAVAREA warnings are applied.

Croatia Master Mariner: Suggested Study Strategy

1Practice ship stability calculations rigorously: calculate GM, free surface moments, list resulting from shifting weights, and distinguishing between a positive GM list and negative GM angle of loll.

2Review COLREGs Rules 1 to 19 thoroughly, specifically action in restricted visibility (Rule 19) and vessel traffic service interactions (Rule 10).

3Understand the statutory powers and obligations of the Master under the Croatian Maritime Code (Pomorski zakonik), including shipboard discipline, birth/death records, and maritime protest.

4Rehearse standard IAMSAR search and rescue patterns (Expanding Square, Sector Search, Parallel Track) and communications procedures on VHF Channel 16 and MF 2182 kHz.

5Memorize tropical storm avoidance rules: determine whether your vessel is in the dangerous semicircle or navigable semicircle and take appropriate evasive courses.

6Master electronic chart parameters: configure safety contour, safety depth, and shallow/deep contour settings on ECDIS to prevent grounding alerts.
