5.0 Stars
Maritime Master IALA Buoyage makes the buoyage system genuinely easy to learn. Sixteen marks across both IALA regions are explained with clear visuals, animated lights, and exam-focused study tips, then tested with quizzes that show you exactly where you stand.
Buoyage questions appear in every theory paper from day skipper to OOW, and light characteristics trip up even experienced crews at night. This app drills both until they are automatic.
Every Mark Explained
Study the four cardinal marks with their clock-face flash logic, port and starboard laterals and preferred channel marks for both Region A and Region B, and the isolated danger, safe water, special, and emergency wreck marks.
Each mark covers its colour, shape, and topmark, its light characteristics and variants, where it is used, how to pass it, and the study tips examiners love to probe.
See the Lights at Night
Flip any mark into night mode to watch its light flash in real time beside a scrolling rhythm timeline, then switch between light variants to learn every characteristic a mark can show. It is the fastest way to connect a flash pattern in the dark with the mark that owns it.
Build Any Light Character
The light simulator lets you construct any IALA light from twenty rhythm patterns, including occulting, isophase, flashing, quick, very quick, ultra quick, and Morse, in five colours with adjustable periods and group counts. As you build, the app generates the correct chart notation, so Fl(2+1) R 10s stops being a puzzle and starts being a picture.
A Complete Rhythm Reference
A categorised catalogue of light rhythms pairs every abbreviation with an animated example and timeline, ready for quick lookup whenever you want to check one.
Test Yourself
Five quiz modes cover buoyage basics, naming buoys from images, light rhythms, animated light pattern recognition, and a fifty question mixed exam. A region selector lets you revise Region A, Region B, or both, so your practice matches your waters.
Simple and Private
Fully offline, no accounts, no tracking, no ads. Open it in a queue and get five useful minutes of revision done.
Who It Is For
Focused revision for day skipper and yachtmaster students, deck cadets, OOW candidates, and anyone keeping their buoyage knowledge fresh. For training and study only, not for real-world navigation.

Frequently Asked Questions
Does it cover Region A and Region B? Yes. Lateral and preferred channel marks are included for both regions, and the quizzes let you filter by region.
Does it work offline? Completely. Everything, including the animated lights and quizzes, runs on your device with nothing to sign up for.
Can I use it to identify marks at sea? No. The visuals are stylised training aids. Always use official charts, light lists, and proper lookout for real navigation.
