## 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 Южно-Африканская Республика

### ***** "Excellent"
Best thing since sliced bread! Very convenient, good lay out and easy to understand. Worth every penny.

### ***** "Excellent!!!!"
I’ve been looking for a COLREGS App that goes into enough details regarding the lights to help me learn for my OOW oral exam, and I would definitely say this is the best app for that by far. It goes very in depth with the lights. It teaches you and test you on everything in such an easy way to understand. Its worth every penny! ⚓️
