Croatia Master Mariner study plan

Croatia Master Mariner · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Navigation

  • Reconstruct from memory the full chart-work sequence for a coastal passage: fix by two bearings, running fix, and transfer of position lines, then verify each step against a reference text

  • Solve 12 terrestrial position-line problems under timed conditions, recording time per problem and error in nautical miles

  • Explain in writing how to correct a gyrocompass bearing to true bearing, including variation, deviation, and the sign conventions for easterly and westerly errors

  • Build a one-page personal checklist of pre-arrival navigation preparations covering passage plan review, notice to mariners, and ECDIS route checks

Your checkpoint

A timed 20-question navigation worksheet scored at 80 percent or better, with all errors reworked and annotated

Week 2

Navigation & Maritime Communications and Electronic Systems

  • Derive the great-circle distance and initial course for two ocean passages using both the haversine formula and spherical trigonometry, and reconcile any difference

  • Describe the operating principles, accuracy limits, and failure modes of GPS, GLONASS, and terrestrial radio navigation systems such as eLoran

  • Explain ECDIS route planning safeguards, including safety contour, safety depth, and the alarms that must be verified before passage execution

  • Interpret the navigational warnings and chart correction workflow from a weekly notice to mariners, listing the steps in order

Your checkpoint

A completed passage plan for a 300-nautical-mile route with waypoints, great-circle legs, ECDIS safety settings, and a written justification of the route

Week 3

Cargo Handling and Stowage & Ship Stability and Construction

  • Calculate deadweight, cargo deadweight, and constant for a given ship from displacement, lightship, and draft survey figures

  • Compute initial metacentric height from a rolling period observation and state the assumptions and sources of error

  • Explain how free surface effect reduces effective metacentric height and calculate the free surface correction for a rectangular tank

  • Classify cargo hazards under the International Maritime Dangerous Goods Code and state the segregation requirements for two incompatible classes

  • Describe the checks required before loading heavy lift or project cargo, including deck strength, lashing calculations, and load-spreading

Your checkpoint

A stability and cargo calculation set of 10 problems with worked solutions, including one full draft survey and one GM calculation from rolling period

Week 4

Ship Operations and Shipboard Management & Emergency Response, Safety and Pollution Prevention

  • Draft a shipboard drill schedule for a three-month period covering fire, abandon ship, man overboard, enclosed space rescue, and oil spill response

  • Explain the master's responsibilities and the chain of command during an emergency, including when to call for outside assistance

  • Outline the content of a muster list and justify each assigned duty by reference to the ship's actual layout and equipment

  • Describe the requirements for a garbage management plan and the record book entries required under the pollution prevention conventions

  • Summarize the reporting obligations and immediate actions following a pollution incident at sea

Your checkpoint

A written emergency response and drill plan for one vessel, including muster list rationale and a completed sample garbage record book page

Week 5

Maritime Law, Conventions and Regulations & Ship Operations and Shipboard Management

  • Map the key obligations of the International Convention for the Safety of Life at Sea, the MARPOL Convention, and the Standards of Training, Certification and Watchkeeping Convention onto the master's daily duties

  • Explain port state control inspection scope, the meaning of a detention, and the master's rights and obligations during an inspection

  • Describe the survey and certification cycle for a cargo ship, naming the certificates and their maximum validity periods

  • Explain the master's authority and obligations regarding seaworthiness, deviation, and refusal to sail under the relevant liability regime

Your checkpoint

A two-page legal obligations summary written from memory, then checked against source texts, with every correction highlighted

Week 6

Meteorology and Oceanography & Marine Engineering and Ship Systems

  • Interpret a synoptic chart and a 500 hPa chart to forecast wind shift, visibility, and sea state for a 24-hour window

  • Explain the formation and warning signs of tropical revolving storms and state the avoiding manoeuvre for both hemispheres

  • Describe the operation of the main engine, steering gear, and auxiliary systems well enough to diagnose three common at-sea failures

  • Explain the checks and procedures for taking over an unmanned machinery space and for responding to a blackout

Your checkpoint

A 24-hour weather routeing decision memo plus a machinery fault-diagnosis sheet covering three failure scenarios with corrective actions

Week 7

Maritime Communications and Electronic Systems & Emergency Response, Safety and Pollution Prevention & Maritime Law, Conventions and Regulations

  • Demonstrate correct use of the Global Maritime Distress and Safety System for distress, urgency, and safety communications, including the priority order of alerting

  • Explain the carriage and testing requirements for emergency position indicating radio beacons and search and rescue transponders

  • Describe the master's obligations under the International Regulations for Preventing Collisions at Sea for a close-quarters situation, justifying each action by rule number

  • Outline the content of a search and rescue plan for a man overboard in different weather conditions

Your checkpoint

A written communications and collision-avoidance exercise: one distress scenario scripted message by message, and three close-quarters situations resolved with rule citations

Week 8

Navigation & Cargo Handling and Stowage & Ship Operations and Shipboard Management & Ship Stability and Construction & Meteorology and Oceanography & Maritime Law, Conventions and Regulations & Marine Engineering and Ship Systems & Maritime Communications and Electronic Systems & Emergency Response, Safety and Pollution Prevention

  • Complete two full-length mixed-domain mock examinations under timed conditions and score each against the answer key

  • Identify the three weakest domains by mock score and rework every missed question with a written explanation of the correct reasoning

  • Recite from memory the key numerical constants, formulas, and certificate validity periods used across all domains

  • Rehearse the oral examination format by explaining stability, collision avoidance, and emergency response topics aloud to a study partner or recording

Your checkpoint

Two scored mock examinations with a written remediation log for every incorrect answer and a final one-page formula and constants sheet

Milestones

Week 2: Score at least 80 percent on a 30-question navigation-only test and complete the 300-nautical-mile passage plan without reference to notes during the final drafting

Week 4: Produce the emergency drill plan and stability calculation set unaided, and explain free surface correction and GM from rolling period aloud without prompts

Week 6: Correctly interpret a synoptic chart and forecast a 24-hour wind and visibility trend, and diagnose three machinery failures with plausible corrective actions

Week 8: Average at least 75 percent across two full mixed-domain mock examinations with no domain below 60 percent
