## COLREG 72 Description
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 Transport Canada or international 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
- Exam mode — a timed mock exam across all the rules with a final score and a full mistake review
- 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.

EXAM MODE

Simulate the real exam. The exam is timed and draws questions from across all the rules. When time runs out, you get a clean result screen with your score and every mistake listed. Tap a wrong answer to see the explanation, the original comment from the question card, and a direct link to the relevant rule — so every attempt teaches you something.

READING

Reading is fully customizable: choose from multiple font types, adjust the font size, and switch between three color themes — light, sepia, and dark — for comfortable study in any lighting condition. Layouts are tuned for both iPhone and iPad.

WHO IT IS FOR

- Maritime students at nautical colleges and academies
- Merchant navy officers and Transport Canada certificate of competency candidates
- Yacht skippers and offshore sailors
- Coastal and recreational boaters who need a reliable collision avoidance reference
- Anyone preparing for a Transport Canada or international maritime authority exam

WHY COLREG 72

International collision avoidance rules are the foundation of safe navigation. Whether you are studying for the first time or refreshing your knowledge before an exam, this app gives you the full text, visual aids, practice tests, and a realistic exam mode to build true confidence.

One-time purchase. No subscription. No ads. Study offline, anytime.

Download COLREG 72 and arrive at your exam prepared.
