Description

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.

Overall pretty good

PiratePetey on

United Kingdom

Good way to go about learning the rules as they’re broken down into sections in a way that could assist in learning them by heart better. The pictures and overall layout is nice and the UI is simple and effective. Lights observations, the wording could be a lot better for some of these, missing out some crucial aspects on how we should formulate proper answers to orals questions for UK exams at least. There should be more situational questions that would be framed in the same way you would expect in an orals exam e.g identify vessel, identify the situation, identify the action and under which rule you are taking action.

Very informative

At first I found this app to be fairly daunting when I opened it. There are approximately 68 different sections to learn. However, once I got started I found the app to be very informative, as easy to understand as colreg rules can be and I also like the different style of questions. In summery, I think this app is very useful for anyone considering EDH, AB or Cadetship.

Great for prep!
