RadarPlot vs The OOW Bible

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.

**The Bible for all present & future OOWs.** **The complete reference for every Officer of the Watch — from exam prep to bridge watch.** The OOW Bible covers every topic on the MCA Officer of the Watch (Unlimited) syllabus in a single app. Whether you're sitting Part A and Part B for the first time, or you're a qualified OOW refreshing your knowledge before stepping back on the bridge, this is the reference you'll reach for. **START WITH A 7-DAY FREE TRIAL** Try every Premium feature free for 7 days — no charge until day 8. Cancel any time during the trial and you won't pay a thing. **PART A EXAM SIMULATOR** Replicate the real My Know exam experience with all five question types: • Multiple choice • True/False • Matching • Fill in the blank • Drag and drop 15 questions. 40 minutes. No returning to previous questions — just like the real thing. Per-topic pass threshold tracking (COLREGs & Buoyage 90%, Nav Procedures 80%, Overall 70%) so you always know where you stand. **AI ORAL EXAM SIMULATOR** Practice your Part B oral with an AI examiner powered by Claude (Anthropic). Two modes: • **Session Mode** — A full multi-turn oral examination on a scenario. The AI asks follow-up questions, challenges your answers, and rates each exchange. • **Quick Assessment** — Submit a free-text answer and get a structured grading report: verdict (PASS / BORDERLINE / FAIL), score, key points checklist, missed topics, and examiner commentary. **SPACED REPETITION FLASHCARDS** Over 1,400 flashcards across all 10 modules, powered by the SM-2 spaced repetition algorithm. The app learns what you know and what you don't — surfacing the right cards at exactly the right time to build lasting knowledge, not just short-term memory. **10 COMPLETE MODULES** Navigation · COLREGs & Buoyage · Radar & ARPA · Meteorology · Watchkeeping & BRM · Ship Stability · Cargo Operations · Safety & Legislation · Emergency Response · Ship Handling All mapped to MIN 653 (Amendment 1, November 2024). **QUICK REFERENCE LIBRARY** 10 instant-access reference topics — not buried in lesson content, just the rules and data you need: IALA buoyage · COLREGs lights & shapes · Sound signals · VHF channels · Beaufort scale · Douglas sea scale · Distress signals · IAMSAR SAR patterns · Day shapes · Light characteristics Useful for exam candidates drilling topics. Just as useful for the OOW heading back to sea after a rotation ashore who needs a fast, reliable refresher before stepping onto the bridge. **GAMIFICATION** XP, levels, streaks, and daily challenges keep you consistent through months of exam prep. **WORKS OFFLINE** Everything — flashcards, lessons, quick reference, exam simulator — works completely offline. Whether you're studying at sea or on a long-haul flight. --- *The OOW Bible is an educational study tool and is not affiliated with, endorsed by, or produced by the Maritime and Coastguard Agency (MCA).
