## Master-Nav Description
Master-Nav is a progressive COLREGS learning system developed by a Master Mariner. The COLREGS are notoriously difficult to learn and retain — Master-Nav makes it significantly easier through an interactive system built around how your brain actually works.

Instead of guessing through random question banks, Master-Nav guides you step by step through every rule from start to finish. Wrong answers are revisited until the rules stick — properly.

Complex regulations are broken down into learnable chunks — bite-sized sections supported by mnemonics, memory aids and interactive visuals designed around how the brain actually retains information.

Every incorrect answer is shown graphically alongside the correct one — immediately clear, no confusion. And with a single tap, the relevant COLREGS rule is accessible from any question at any time.

Master-Nav covers COLREGS Parts A to D — General, Steering & Sailing, Lights & Shapes and Sound & Light Signals — plus Annex IV Distress Signals. Over 1000 questions in multiple formats, with a dedicated Practice Section that tracks right, wrong and unanswered so you always know where to focus.

COLREGS — the easy way.

## Master-Nav Reviews in Великобритания

### ***** "Brilliant app"
Helped me pass my signal exams first try by just using the app for 2 days!
-- LloydyMac, 2024-11-19

### ****- "Overall pretty good"
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.
-- PiratePetey, 2024-07-07

### ***** "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.
-- Chimmy o è Paets, 2023-03-09

### ***** "Great for prep!"
Doing my oral prep. This App really helped - loads of questions, with quick access to the rule that the question is about.
-- sstevens88, 2022-07-19

### ***** "Great app for Yacht Crew!"
Taught me so
Much - easy to use and test myself. Absolutely must have for navigation expertise.
