Marine Vessel Nav Lights is an educational navigation reference that helps mariners identify vessel lights and day shapes and master the Rules of the Road. It features an interactive library of COLREGs-compliant light configurations with clear diagrams and real photos, filterable by vessel type, length, status, and operating area. A Quick Identify tool lets you select observed colors, arcs, and positions to match likely vessel types and see the relevant rule and safe action. Practice and exam prep include quizzes, flashcards, and real-world scenarios for boating safety courses, sailing certifications, and USCG exams. Accurate, easy to use, and available offline, it’s ideal for students, sailors, and professional crew seeking reliable maritime training.
