Master COLREGS navigation lights, day shapes and sound signals with focused quizzes and offline spaced-repetition practice. Recognise navigation lights, day shapes, and sound signals quickly and confidently. Steerage is an image-first COLREGS study trainer for RYA Day Skipper and Yachtmaster revision, maritime cadets, USCG rules-of-the-road candidates, and boaters refreshing essential knowledge. Accurate light patterns are generated from a rules-based model and shown from ahead, astern, port, and starboard aspects. Use spaced-repetition flashcards for daily practice, run timed 10-question quizzes, compare commonly confused displays, and track readiness and weak areas. Concise rule summaries and International/US Inland notes explain each answer without turning practice into a dense rule-book browser. The free starter deck includes core lights, manoeuvring signals, and encounter rules. A single lifetime in-app purchase unlocks the complete 200+ card pool, every focused quiz mode, day shapes, sound signals, and the full vessel catalog. No subscription and no ads. Training content and progress are stored locally and work offline. No account is required. Apple and RevenueCat process purchase information needed to provide and restore the lifetime unlock; see the privacy policy for details. Training aid only. Not a substitute for official COLREGS / Navigation Rules publications.
