EU Boatmaster (Hungary) common mistakes
EU Boatmaster (Hungary) · Understand the traps and how to avoid them.
Applying COLREG head-on, crossing and overtaking rules unchanged on inland waterways instead of applying the CEVNI hierarchy (special signals, blue boards/blue lights, sound signals for overtaking on the 'wrong' side), and failing to give priority to vessels showing the blue board or blue flashing light.
Most candidates learn COLREG first and treat CEVNI as a vocabulary list, so under time pressure they default to the at-sea rule set; the blue-board/blue-light priority and the inland overtaking signal sequence are the parts that differ most and therefore get overwritten by the familiar COLREG pattern.
What to do instead
Build a one-page comparison table: for each situation (head-on, crossing, overtaking, narrow channel, meeting at a bridge arch) write the COLREG answer and the CEVNI answer side by side, and drill the CEVNI column until it is the first answer that comes to mind. Practise the overtaking sound signal sequence (two short / two long and two short / etc. as required) aloud until it is automatic.
Misreading the day shapes, lights and sound signals of a vessel constrained by its draught, a vessel at anchor in fog, or a vessel showing the 'not under command' signals, and then choosing the wrong avoiding action (turning across the bow instead of standing on or giving way correctly).
These are low-frequency cases in day-to-day boating, so candidates memorise them as isolated facts without linking the signal to the manoeuvring obligation it creates for the other vessel; the light/shape is recognised but the consequence is not.
What to do instead
For every special-status signal (NUC, RAM, constrained by draught, fishing, sailing, towing, pushing) write down three things: what the other vessel must do, what it must not do, and the sound signal in restricted visibility. Test yourself by drawing the light configuration from memory, then stating the obligation.
Answering stability questions by intuition ('more weight low is always better', 'a list means the cargo shifted') without using GM, KG, free surface effect and the rolling-period relationship, and confusing list with loll and heel with trim.
Stability is the most mathematical topic on the paper and candidates avoid the formulas during study, so they fall back on everyday reasoning; the vocabulary (list, loll, heel, trim, GM, GZ) is also easy to blur under exam pressure.
What to do instead
Memorise and use four relationships until they are reflexive: GM = KM − KG; a long rolling period means a small GM (stiff vs tender); free surface effect always reduces effective GM; a list is a steady heel to one side while loll is an unstable swing across the upright. Work at least ten numerical GM/KG problems with the formula written out each time.
Planning a passage or a bridge/lock approach without converting chart datum, water-level gauge readings and air-draught figures into the actual clearance available at the time, and without allowing for squat, bank effect and the vessel's own air draught.
Candidates treat charted depths and bridge heights as fixed numbers and forget that the exam expects them to add the current gauge reading, subtract the vessel's draught plus under-keel clearance, and account for squat increasing with speed in shallow or confined water.
What to do instead
Use a fixed calculation template for every clearance question: available depth = charted depth + gauge reading − draught − under-keel clearance − squat; available air draught = charted clearance − gauge rise − antenna/mast height. Practise with realistic Hungarian Danube gauge figures and state each allowance explicitly in the answer.
Giving vague or incomplete Mayday/Pan-Pan/Sécurité traffic: omitting position, nature of distress, number of persons on board, or the correct priority and radio channel, and mixing up DISTRESS, URGENCY and SAFETY prefixes.
Candidates learn the words of the distress call but not the discipline of the message structure, and they confuse when a Pan-Pan (urgency) is required instead of a Mayday; in inland practice the correct channel and the Inland AIS/ATIS context are also often skipped.
What to do instead
Write the full Mayday template from memory (Mayday ×3, this is, name ×3, callsign, position, nature of distress, assistance required, persons on board, over) and rehearse it aloud in under 30 seconds. Then write the Pan-Pan and Sécurité versions and state one concrete example for each so the boundary is clear.
Treating Inland AIS as a passive display: not setting the correct navigational status, ship dimensions, destination or blue-board/convoi data, and not understanding that AIS does not replace look-out or the radiotelephone agreement for passing arrangements.
AIS is taught as equipment operation rather than as a data-quality and collision-avoidance responsibility, so candidates answer 'the AIS will show it' instead of describing look-out, VHF contact and the correct status settings.
What to do instead
Learn the Inland AIS status list and the mandatory data fields (ship dimensions, convoy configuration, hazardous cargo, blue board) and be able to state what each status means for other traffic. Answer every AIS question by first naming the look-out/COLREG obligation, then the AIS contribution.
Answering firefighting questions with the wrong agent or the wrong action for the fuel type - water on a fuel fire, opening a closed compartment to inspect, or failing to shut off fuel and ventilation before attacking the seat of the fire - and not knowing the fixed CO2/foam system release procedure.
Candidates memorise the fire triangle and extinguisher colours but not the decision sequence, and the instinct to 'open it and look' or 'throw water on it' survives into the exam answer because it was never explicitly corrected.
What to do instead
Drill the sequence for each space (engine room, galley, accommodation, battery space): stop fuel/ventilation, raise alarm and close up, choose agent (foam for fuel, CO2 or clean agent for electrical, water only for Class A solids), cool boundaries, then boundary cooling and re-entry checks. State the fixed-system release preconditions (all personnel accounted for, space sealed) in every answer.
Failing to apply the man-overboard and abandon-ship sequence in the right order - not immediately putting the helm over to the side of the casualty, losing sight of the person, or forgetting the Williamson turn and the recovery/drift calculation - and confusing the abandon-ship decision authority.
The MOB drill is learned as a slogan ('helm over, shout, throw') without the sequence, the turning manoeuvre and the recovery approach, so under exam pressure candidates give the first action but not the complete drill or the interaction with propellers and the person in the water.
What to do instead
Write the MOB drill as a numbered checklist including helm to the casualty side, shout 'man overboard' and press MOB on the plotter/AIS, throw buoyant aid, post a lookout, execute the appropriate turn (Williamson or Anderson), approach into wind and current, stop the propeller, recover. Then write the abandon-ship sequence and who gives the order.
Ignoring the human element: planning a passage or watch without rest hours, fatigue countermeasures, or a clear bridge resource management briefing, and answering medical/fitness questions with 'call a doctor' rather than the required assessment, recording and reporting steps.
Candidates treat fatigue, fitness and CRM as soft topics that need no specific knowledge, so answers stay generic; the exam expects concrete limits (rest hours, alcohol limits, validity of the medical certificate, fitness for duty assessment) and the reporting chain.
What to do instead
Memorise the concrete numbers and steps: minimum rest hours and maximum watch length applicable to the certificate, alcohol limits, medical certificate validity and the conditions that invalidate it, and the sequence for a crew member unfit for duty (assess, relieve, record, report to the master/authority). For CRM, name three specific briefing items (passage plan, roles, communication protocol) rather than generalities.
Answering pollution and legal questions from general principle rather than the specific rule: not knowing which discharges are prohibited, the garbage and oil record-keeping and reporting duties, the obligation to report a pollution incident, or the certificate and crewing documents that must be on board for the vessel and route.
Environmental and administrative topics are read once and assumed to be common sense, so candidates produce plausible but non-specific answers and miss the documentary and reporting obligations that carry marks.
What to do instead
Build a one-page 'on board and on the record' sheet: certificates and documents required for the specific vessel category and waterway, the discharge prohibitions and reporting duty for oil/garbage/sewage, and the incident-reporting chain (master, authority, flag/port state). Test yourself by listing them from memory, then check against the regulation.
