This free quiz provides an in-depth review of the IALA Maritime Buoyage System in English — the global framework that standardises the use of buoys, beacons and lights to guide vessels safely. Each session draws 20 questions at random from a bank of 40 covering both theory and practical application.
Topics covered: IALA Region A vs IALA Region B (which countries use each system), the five mark types (lateral, cardinal, isolated danger, safe water and special marks), light characteristics (Fl — flashing, Oc — occulting, Iso — isophase, Q — quick, VQ — very quick, LFl — long flashing, Mo(A) — morse), topmarks for all four cardinals and isolated danger marks, and the practical rules for entering and leaving a harbour.
Ideal for sailors preparing the PY or CY nautical exam in English, and for anyone navigating in international waters where buoyage literacy is essential for safety.
