Master-Nav: Colregs

Master-Nav: COLREGS is a progressive learning app designed by a Master Mariner to make maritime navigation rules easier to understand, remember, and pass. Instead of relying on random question banks, it guides learners through every rule step by step, revisiting incorrect answers until the knowledge sticks.

The app covers COLREGS Parts A–D—General, Steering and Sailing, Lights and Shapes, and Sound and Light Signals—plus Annex IV Distress Signals. Bite-sized lessons, mnemonics, memory aids, interactive visuals, instant graphical explanations, and one-tap rule references support effective learning. With more than 1,000 questions and a practice section tracking correct, incorrect, and unanswered responses, Master-Nav helps maritime students and professionals focus their preparation.
