Nanu ROR Visual Deck Live

Nanu ROR Visual Deck is a complete, fully offline training reference for the International Regulations for Preventing Collisions at Sea (COLREG / "Rules of the Road"). Study all 41 rules with plain-language explanations and bridge application notes, drill navigation lights and day shapes across dozens of vessel profiles, play back sound and light signals, learn IALA buoyage, and work through a large generated exam question bank with flashcards and oral-practice prompts. The Encounter Lab is a give-way/stand-on bridge simulator: choose a vessel type for your own ship and a target, switch between day and night rendering, and get a live verdict — with the exact rule citation — computed from the Steering and Sailing Rules as the situation develops. Risk of collision and close-quarters situations are flagged in real time. Rules, Lights & Shapes, Sound & Light, Distress, IALA Buoyage, Annexes, Radar Plotting, Flashcards, and Progress are free, always. A single one-time purchase unlocks the Encounter Lab bridge simulator, Oral Practice, and Exam Mode. Outside of that one optional purchase, everything works with no internet connection and no account: all content is bundled in the app, and your exam history, favourites, and progress stay on your device. Nothing is collected or transmitted. This is a training and revision aid only. It does not replace the official COLREG text, flag-State examinations, or approved courses, and does not model every rule (e.g. restricted visibility, narrow channels, or traffic separation schemes) at full operational fidelity.
