EU Boatmaster (Flanders) common mistakes
EU Boatmaster (Flanders) · Understand the traps and how to avoid them.
Applying CEVNI (blue signs, Section A) as if it were the maritime COLREG regime, or vice versa, when reading a buoy, sign or light on a waterway where both systems meet, instead of first identifying which regime governs the water being navigated.
Candidates study COLREG and CEVNI in separate blocks and never practise the transition points (harbour mouths, river-sea junctions, canalised estuaries), so under exam pressure they reach for whichever rule set they revised last. The two systems use different buoyage colours, shapes and light characters, so the error produces a confidently wrong answer.
What to do instead
Build a one-page comparison table of CEVNI versus COLREG for buoyage, sound signals, lights and right-of-way, and drill ten mixed scenario questions where the first step is always to name the applicable regime and the evidence for it. On the exam, write the regime and its justification before choosing the sign or mark.
Treating a narrow channel, bridge arch or lock approach as a normal overtaking situation and answering that the faster vessel may pass, rather than stating that the vessel proceeding upstream or with the current has priority and that the downstream or entering vessel must wait.
Candidates memorise 'give way to the right' and generic overtaking rules and do not connect them to the specific priority articles for bridges, locks and narrow channels. The phrasing of exam scenarios often hides the current direction, so candidates assume the more manoeuvrable or faster boat has right of way.
What to do instead
Learn the priority hierarchy explicitly: at bridges and locks the vessel with the current or proceeding downstream normally has priority, and the other vessel waits. Practise reading scenarios to extract current direction and traffic direction first, then apply the hierarchy, and rehearse the standard signals for requesting passage.
Answering berthing and lock-entry questions by describing rudder and throttle inputs only, without mentioning spring lines, current set, wind effect on the bow, or the use of an anchor to check way, so the manoeuvre described would fail in practice.
Candidates revise manoeuvring as a list of helm commands and underestimate how much of the mark comes from planning: approach angle, abort point, line handling and contingency. They also confuse the effect of prop walk and transverse thrust with rudder effect, giving answers that are internally consistent but physically wrong.
What to do instead
Answer every manoeuvring question with a four-part structure: assess wind and current, choose approach angle and abort point, state line or anchor plan, and name the contingency. Practise explaining transverse thrust and paddle-wheel effect aloud, and rehearse the spring-line technique for leaving a berth against wind or current.
When asked who gives way in a crossing or head-on situation, answering with the give-way vessel's action only and omitting the stand-on vessel's duty to hold course and speed and, once risk of collision is unavoidable, to take action.
Candidates learn the give-way rule as a single sentence and forget that the stand-on vessel has obligations too. Scenario questions that ask 'what should each vessel do' are then answered one-sidedly, losing the marks for the stand-on duty and for the point at which that duty changes.
What to do instead
For every collision-avoidance question, answer in three parts: who gives way, what the give-way vessel does (early and substantial), and what the stand-on vessel does before and after the risk becomes unavoidable. Learn the sound and light signals that accompany each action so the answer is complete.
Describing sound signals and light configurations from memory without checking the vessel category, so a vessel engaged in pushing, a ferry, a fishing vessel or a vessel at anchor is given the wrong signal or the wrong arc of visibility.
The signal tables are numerous and similar, and candidates learn them by visual pattern rather than by vessel type. Exam questions deliberately swap one element (number of strokes, colour, sector) and the memorised pattern fails.
What to do instead
Rebuild the signal tables from first principles by vessel type, then self-test with deliberately altered versions of each signal, deciding what the alteration would mean. For lights, always state colour, number, sector and relative position in that order so a wrong element is caught before it is written down.
Reciting the steps of a man-overboard or fire response as an unordered list, omitting the immediate actions that come first: shout and mark the position, throw buoyancy, reduce speed and turn, and only then call for assistance.
Candidates learn emergency procedures as checklists to be recalled, not as time-ordered actions, and examiners award marks for sequence. Under stress the list is recalled in whatever order it was last read, so the first action becomes the mayday call rather than the immediate lifesaving action.
What to do instead
Learn each emergency drill as a timed sequence with a mnemonic anchored to the first three seconds, first thirty seconds and first five minutes. Rehearse by writing the drill from memory in order, then checking against the sequence, until the order is automatic.
Answering first aid and firefighting questions with the definitive treatment rather than the correct immediate action, for example describing how to move a casualty with a suspected spinal injury or opening a closed compartment fire door to attack the seat of the fire.
Candidates transfer general knowledge from everyday life, where the intuitive action is to help the casualty move or to get at the fire directly. On board, the correct answer is usually to keep the casualty still and to starve, cool and contain the fire before any direct attack.
What to do instead
Learn the small set of rules that override intuition: do not move a suspected spinal casualty unless there is immediate danger, do not open a closed compartment, cool boundaries before attacking, and never use water on a fuel or electrical fire. Practise classifying each scenario by hazard before choosing an action.
Treating weather and tide questions as vocabulary recall, so a candidate can define a depression or a spring tide but cannot say what the wind shift, sea state or tidal stream will do on a specific stretch of waterway in the next few hours.
Meteorology and hydrology are revised as definitions rather than as predictions, and candidates do not practise reading a pressure chart or a tide table and converting it into a decision about whether to sail, where to shelter, or how much water to expect under the keel.
What to do instead
Practise with real charts and tide tables: from a given pressure pattern, state the expected wind direction and strength, the likely change in the next six hours, and the operational decision. For tides, calculate height of tide and tidal stream at a stated time and check the answer against the table.
Answering stability questions by quoting the metacentric height or the free-surface effect as a definition, without applying it to a concrete loading case such as a partly filled tank, a deck cargo or a boat loaded with passengers all on one side.
Stability is taught as theory and candidates can reproduce the definitions but not translate them into the effect on a specific vessel. Exam scenarios describe a loading change and expect the candidate to state the consequence for righting lever, list and freeboard.
What to do instead
For each stability scenario, work through four questions in order: what changed, how did the centre of gravity move, what happened to the righting lever, and what does the master do about it. Learn the free-surface effect as a loss of metacentric height proportional to the tank breadth cubed, and apply it to a worked example.
Giving environmental and administrative answers that are technically correct but incomplete: naming the garbage category without the discharge restriction, or stating that a certificate is required without the validity, the issuing body and the record-keeping duty.
Candidates revise the legal and environmental domains last and in summary form, so they recall the headline rule but not the conditions attached to it. Examiners award marks for the conditions, which is exactly what the summary revision omits.
What to do instead
For each rule, learn it as a triple: what is prohibited or required, under what conditions or exceptions, and what record or document proves compliance. Build a table of MARPOL-type discharge categories, and a second table of certificates with validity and issuing authority, and test yourself on the conditions rather than the headline.
