COLREG 72 is a complete study and reference app for the International Regulations for Preventing Collisions at Sea (COLREGs). Built for maritime students, merchant navy officers, yacht captains, and anyone preparing for a maritime exam.
WHAT IS INCLUDED
- Full text of all 72 COLREG rules (Annexes I through IV)
- Theory study with illustrations
- Navigation lights identification quizzes
- Rule-based tests with answer explanations
- Cross-references between rules and theory — open in popup overlays so you never lose your place
HOW IT WORKS
Theory and rules are linked throughout the app. When you answer a quiz question incorrectly or open a hint, a direct link appears to the exact theory section that covers the topic. Review the rule, then return to the quiz.
The app tracks which theory sections you have read, so you always know where you left off and what still needs attention.
Reading is fully customisable: choose from multiple font types, adjust the font size, and switch between three colour themes — light, sepia, and dark — for comfortable study in any lighting condition.
WHO IT IS FOR
- Maritime students at nautical colleges and academies
- Merchant navy officers preparing for OOW, Chief Mate, or Master exams
- Yacht skippers and RYA / ASA candidates
- Coastal and offshore sailors who need a reliable collision avoidance reference
- Anyone sitting a maritime authority exam (MCA, USCG, AMSA, Transport Canada, MNI)
WHY COLREG 72
International collision avoidance rules are the foundation of safe navigation. Whether you are studying for the first time or refreshing knowledge before an exam, this app gives you the full text, visual aids, and practice tests to build real confidence.
