Lights and Shapes vs RadarPlot

Experience maritime rules like never before! This app helps you master navigation lights and shapes with interactive 3D models you can rotate and zoom. Instantly see how the appearance of vessels changes from different angles—day or night. Identify any ship, understand its route, and know the right of way to avoid collisions. Perfect for boaters, students, and maritime professionals. Features: - Official text of the rules - 30 interactive 3D vessel models (day & night views) - 50+ flashcards for quick recognition and self-testing Make learning the rules of the sea engaging and effective!

Master radar plotting through practical, interactive exercises. RadarPlot is a professional training tool for maritime cadets, deck officers and navigators learning the 6-minute plotting method, relative motion, CPA calculations and collision-avoidance maneuvers. PRACTICE RADAR PLOTTING • Record target range and bearing observations • Plot multiple radar targets • Use a North-Up stabilized radar display • Adjust plotting intervals and range scales • Zoom and pan without affecting calculations CALCULATE CPA AND TARGET MOTION • Automatically construct the Relative Motion Line • Calculate CPA, TCPA and relative speed • Determine the target’s true course and speed • Visualize own-ship and target-motion vectors • Practice the standard 6-minute plotting method PLAN COLLISION-AVOIDANCE MANEUVERS • Set a required minimum passing distance • Calculate course-only and speed-only solutions • Select the maneuver execution point • Display the Advanced Relative Motion Line • Compare alternative maneuvering decisions BUILT FOR MARITIME TRAINING Use built-in scenarios and answer-reveal tools to learn step by step or practise independently. Ideal for maritime academy students, deck officers preparing for examinations, navigators refreshing manual plotting skills and instructors demonstrating relative-motion geometry. Train smarter. Understand the plot. Make safer decisions.
