Master-Nav 4+

Developed by a Master Mariner. Master-Nav is a progressive learning system with over 1000 questions, which makes it easy to learn, memorise and refresh the COLREGS.

Master-Nav makes learning COLREGS easy with its comprehensive learning system that leverages the natural learning mechanisms of the brain. Our goal is to simplify your preparation for maritime qualifications and maximize your success. Instead of diving into dense rule books, our application uses interactive visuals, memory aids, and exam answer phrases for an engaging and intuitive learning experience.

Start with the Learning Section to understand the rules step by step, then move to the Practice Section to reinforce your knowledge and improve your performance. Master-Nav covers COLREGS Part A to Part D (Rules 1-37) and the distress signals found in Annex IV thoroughly. With over 1000 questions in various formats, each supported by clear graphic answers highlighting errors, Master-Nav reinforces your knowledge through repeated practice, making rule retention effortless.

Our app-wide Rule button simplifies navigating the COLREGS Rule book. A single click gives you quick access to the relevant COLREG rule for the question at hand, saving valuable study time.

To make complex rules with technical terminology more understandable, we provide explanations in simple language. We understand that maritime regulations can be dense, especially for newcomers to the field.

Whether you're a cadet starting your maritime career or an experienced mariner refreshing your understanding of the COLREGS, Master-Nav is the ideal learning tool. Experience the convenience, effectiveness, and painless rule memorization our app provides.
