RadarPlot vs HMS ColRegCards

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.
