Master the Racing Rules of Sailing — before your next regatta. RRS Coach is the complete study companion for sailors who want to understand and confidently apply the Racing Rules of Sailing (World Sailing 2025–2028). Whether you're preparing for your first race or sharpening up before a major event, it gives you the rules, the practice and the answers in one app. THE INTERACTIVE SIMULATOR Set up the boats, drag the wind, press play, and watch right of way resolve live. Boats sail properly — speed depends on your angle to the wind, and a tack costs you speed. The simulator explains itself as you go: mark-room and Rule 18, Rules 15 to 17 as rights change, and a hail of "Room to tack!" at an obstruction under Rule 20. In Predict mode it pauses as the boats close and asks you who must keep clear, before it shows you. WHO HAS RIGHT OF WAY? Describe the situation in three taps — who's on which tack, who's ahead, where the mark is — and get an instant answer: what you must do, what they must do, and the rule behind it. LEARN THE RULES All 82 World Sailing rules in plain English, organised by part and fully searchable, with the official World Sailing PDF in-app. Every one of the 24 defined terms — proper course, mark-room, the zone, keep clear — is tappable inside any rule you're reading. 11 US Sailing prescriptions included, plus 41 plain-language guides. SCENARIOS AND QUIZZES 94 real racing scenarios — mark roundings, port and starboard crossings, tacking situations, protest cases — each with a boat diagram and the exact rule behind the ruling. 122 quiz questions filtered by difficulty and rule set, plus a timed exam mode with full statistics. PROTESTS A step-by-step walkthrough from the on-water hail to the protest committee hearing — and a validity check for the hail, the red flag and the time limit, which is where most protests actually fail. RACE SIGNALS All 25 signal flags: what each means, when it's used, the rule behind it. Learn them by ear with the horn patterns the committee actually sounds, watch the 5-4-1-0 start sequence play out, and test yourself with the sound quiz. STUDY THAT ADAPTS TO YOU A three-minute baseline test maps where you stand, part by part. Spaced-repetition flashcards put what you keep missing first. Racing soon? Set your next regatta and get a countdown with a daily goal paced to cover your weak spots. Plus a daily challenge, streaks, bookmarks, progress tracking and achievements. BUILT FOR THE BOAT PARK Works fully offline. Light and dark themes, text size that follows your phone, home-screen widgets, and backup and sync across your devices. FREE AND PRO Download free and keep the full rule library, the glossary, the protest guide, the right-of-way answer tool, 5 scenarios and 20 quiz questions. One optional in-app purchase unlocks everything else — a one-time purchase, not a subscription. RRS Coach is an educational reference tool and is not affiliated with or endorsed by World Sailing.
