Croatia Master Mariner study plan
Croatia Master Mariner · Give each week a clear focus.
8 weeks · About 7 hours per week
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
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
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
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
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
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
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
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
