About this app

Master-Nav is a progressive COLREGS learning system developed by a Master Mariner. The Navigation Rules 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.

Ratings and reviews

Best resource for effective learning of COLREGS I've come across. This app has changed the game for me, I struggled before, this has made everything straight forward by following a logical path, constant revision, ability to immediately bring up the relevant regulation and with ability to review any section any time. $3.99 AUD one time payment for the premium has been worth it.

Great app but I would say one weakness is the mnemonics. Mnemonics should be short and memorable, and optional. These are often long and arbitrary, they don't help me memorise things at all. The interface when being tested on them is tedious as well, seems to have problems with my samsung's keyboard app. But other than that useful app for a fair price, thanks!

Pretty good, nice little app to help refresh the memory
