📝 About this app
Stop memorising the regulations. Start mastering them.
Maritime Master - COLREG is the definitive interactive guide to the International Regulations for Preventing Collisions at Sea (COLREGs / IRPCS). Designed for deck officers, yachtmasters, and serious boaters, this app replaces dry textbooks with intuitive visual simulations.
Whether you are preparing for your exams, or simply need a reliable pocket reference at sea, Maritime Master helps you learn faster and retain more.
Most apps just copy-paste the rules. We bring them to life.
Interactive Scenarios: Don’t just read Rule 14 (Head-on) or Rule 15 (Crossing), control the vessels on screen to see exactly who gives way.
Visual Light Sectors: Build the "Mercedes" arc yourself. Finally understand exactly what 112.5°, 135°, and 225° look like in real life.
Smart Quizzes: Test your knowledge with "Exam Trap" questions that highlight common mistakes students make in oral exams.
KEY FEATURES
Complete Rule Book (1-38): Full, searchable text of the Steering and Sailing Rules, perfectly formatted for mobile.
Navigation Lights & Shapes: Toggle between Day, Night, and Fog modes to master Rule 20. See instantly how shapes change for RAM, CBD, NUC, and Fishing vessels.
Restricted Visibility (Rule 19): A dedicated Radar Simulator helps you decide whether to turn to starboard or reduce speed in fog.
Sound & Distress Signals: Interactive buttons to hear blast patterns (Rule 34/35) and visualize Annex IV distress signals like Red Flares and Smoke.
Steering Rules Visualized: * Overtaking (Rule 13): Clearly see the overtaking sector vs. crossing.
Narrow Channels (Rule 9): Master positioning and bends.
TSS (Rule 10): Visualize lane discipline and crossing angles.
Offline Ready: No internet required. Study in your bunk, on watch (if allowed!), or commuting.
PERFECT FOR:
Student Officers: Cadets, OOW, Chief Mate, Master 3000 (MCA / USCG / International).
Yachting Pros: RYA Yachtmaster Offshore / Ocean, Master 200/500.
Leisure Boaters: Day Skipper, Powerboat Level 2, ICC
Sailing Schools: A perfect visual aid for instructors teaching the Rules of the Road.
INCLUDES:
Part A: General
Part B: Steering and Sailing Rules (Sections I, II, III)
Part C: Lights and Shapes
Part D: Sound and Light Signals

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
