Nautly/Guides/What's on the exam
The Croatian Voditelj brodice kategorije B exam is an oral one: you sit before a small commission at a harbour master's office and answer questions out loud, with a little chart work and a few knots at the table. It is broad but shallow — the rules of the road, lights and signals, buoyage, basic navigation, weather, engine sense and radio basics — and none of it is hard once you know what to expect. This guide walks through every subject you'll be asked about and how to study for each. ⓘ NotePossible 2027 law changes could make the theory exam stricter and a practical exam mandatory. Exactly what will change, and when, is still uncertain.

You take the exam in person before an examination commission (an ispitna komisija, usually three members) at a Lučka kapetanija — a harbour master's office — or at the Ministry in Zagreb. It is an oral and theoretical exam, not a multiple-choice quiz and not an on-water boat-handling test. The examiners take turns asking questions and moving across the syllabus; two short practical tasks happen right there at the desk, on a paper chart and a length of rope.
A sitting typically runs 20 to 40 minutes, and the result — passed or failed — is given at the end, usually subject by subject and then overall. Most candidates describe a purely spoken exam, though a few offices are said to add a short written element, so treat the oral exam as the core and confirm the exact shape with your office.
The official programme is usually grouped into five areas: navigation, engines, seamanship, regulations and meteorology, manoeuvring and safety of navigation, and radiotelephony. In practice the questions cluster around a familiar set of topics:
Buoyage is the one area where the world is split in two, so it pays to be sure which half you're in. Croatia, like the rest of Europe, follows IALA Region A. Following the direction of buoyage (broadly, coming in from seaward), you keep red marks to port — on your left — and green marks to starboard, on your right. A useful contrast for anyone who has sailed in the Americas: that is the opposite hand to Region B's "red, right, returning".
Cardinal marks (north, east, south, west) and the isolated-danger mark are the same in both regions, so only the red-and-green lateral marks flip. Croatia's aids to navigation are maintained by Plovput, the national authority, so the buoyage you'll meet on the water matches exactly what you study for the exam.
There is no mandatory course for category B, so you have a genuine choice: study on your own, or take an optional preparation course (tečaj) at a sailing school. Both routes lead to the same exam. A lot of the material is international — COLREG, the phonetic alphabet and chart work are the same the world over — which means you can learn the concepts first in a language you're comfortable in, then attach the Croatian terms you'll actually hear in the room.
Most people prepare comfortably over a few weeks of light study, or compress it into a focused few days if they already have some boating background — which is what makes the licence realistic to earn on a Croatian holiday.
The official syllabus and exam are in Croatian. Some sailing schools say they can arrange the exam in English, German or Italian on request, but this is not an officially guaranteed option and may depend on the examiners available at your chosen office — so if you need another language, confirm it directly with that harbour master's office before you book.
On the radio side, basic marine VHF is part of the B syllabus, so a Croatian B holder is covered to use the boat's radio in Croatia. The standalone Short Range Certificate (SRC) — the full VHF/DSC radio operator's certificate that many charter bases ask to see — is a separate supplementary radio exam (RTF) with its own small fee, not part of category B itself.
It is an oral and theoretical exam taken in person before a commission at a harbour master's office, with short chart work and knots at the table. A few offices are said to add a brief written element, so confirm the format with your chosen office.
A single sitting usually runs about 20 to 40 minutes, and the pass-or-fail result is given at the end. The exact length depends on the office and how the questioning goes.
The rules of the road (COLREG), navigation lights and shapes, sound and distress signals, IALA buoyage, the phonetic alphabet, chart work, knots, basic Adriatic meteorology, basic engine checks and marine VHF radio.
Croatia and the whole Adriatic are in IALA Region A, so following the direction of buoyage you keep red marks to port (left) and green marks to starboard (right) — the opposite hand to the Americas.
No. There is no mandatory course for category B — you can self-study and book the exam directly, or take an optional preparation course at a sailing school. See how to get the licence for the full process.
