About Maritime Master - Radar

Maritime Master - Radar is a simulator designed to help maritime students, deck officers, and enthusiasts practice radar navigation and collision avoidance workflows in a safe, controlled environment. Bridging the gap between theory and the bridge, this app transforms your device into a fully functional radar station. Whether you are refreshing your knowledge of Relative Motion vs. True Motion or practicing the mechanics of target tracking, this simulator offers a realistic "Green Screen" experience powered by Metal graphics for an authentic sweep and decay effect. IMPORTANT: FOR SIMULATION & TRAINING PURPOSES ONLY. This application is a simulator designed for practice and educational reinforcement. It is not a regulated piece of navigation equipment and must not be used for real-world navigation or collision avoidance on a vessel. Key Features: - Realistic Radar Physics: Experience authentic sweep visuals with adjustable Gain, Sea Clutter, and Rain Clutter controls to simulate varying environmental conditions. - Full ARPA Functionality: Acquire and track targets to calculate CPA (Closest Point of Approach) and TCPA. Visualize risks with dangerous target alarms. - Vector Modes: Switch between True and Relative Vectors to visualize target aspect and movement. Adjust vector length (minutes) to predict future positions. - Standard Navigation Tools: Utilize dual Variable Range Markers (VRM) and Electronic Bearing Lines (EBL) to determine range and bearing with precision. - Display Modes: Toggle between Head Up, North Up, and Course Up orientation. Switch the display between Relative Motion (RMTT) and True Motion to understand traffic flow. Scenario Library: Test your COLREGs knowledge with pre-built scenarios including: - Crossing Situations (Stand-on and Give-way) - Overtaking and Being Overtaken - Head-on encounters - Busy waters with mixed traffic types - Coastal navigation with land masking "True View" Overlay: Toggle the underlying map view to compare the radar return against the "ground truth" of the scenario. AIS Integration: Simulated AIS overlays provide target names, types, and kinematic data (COG/SOG) alongside raw radar echoes. Practice Scenarios: The app includes a suite of scenarios designed to test specific competencies. From simple open-water encounters to complex multi-vessel situations involving fishing vessels, cargo ships, and high-speed craft, you can practice your decision-making without the risk. Own-ship Control: Take command of your vessel. Adjust your Heading and Speed to execute collision avoidance manoeuvres and observe the resulting change in Relative Motion on the scope. Whether you are studying for your OOW exams or just want to keep your radar skills sharp, Maritime Master - Radar puts the Plan Position Indicator (PPI) in your pocket.

What’s new

Version 3.1 · Updated July 4, 2026

10 new charts Every watch now ends with a full training Debrief, your score, the closest CPA/TCPA you reached, whether you acted early, missed contacts, and a timeline you can replay. New guided Training Packs (Pro) cover COLREGS crossings, restricted visibility, ARPA tracking, pilotage, the Dover Strait and yacht radar, with goals, badges and shareable certificates. Switch on realistic sensor errors to keep you cross-checking your instruments. Pro Max can export debrief reports for training records. The radar and electronic chart got a big realism pass: filled land returns with radar shadow, receiver noise and antenna side-lobes, an IHO S-52 vector chart with Day/Dusk/Night palettes, safety-contour depth shading, sectored lights, buoy topmarks and a tunable Realism panel.
