ClearShip – Sailing & Boating

ClearShip is your Swiss Army knife for sailing and boating – anchor alarm, emergency assistant, navigation and sailing tools, a nautical dictionary and boat management in one app. Built for the deck: big numbers, glove-friendly controls, works without reception. ⚓ ANCHOR ALARM Drop your anchor point and set the swing radius – or let ClearShip calculate it from chain length, depth and boat length. ClearShip watches your position, even in the background: early warning first, then the full alarm. • Correct the anchor position on the chart afterwards • Silence alarms (30 min to 8 h) – the watch keeps measuring • Warning on GPS loss – never a blind anchor watch • Offline maps and nautical chart overlay for the anchorage • Shared anchor watch for the whole crew • Boat GPS via Signal K: watches the boat, even while you are ashore 🆘 EMERGENCY & MAYDAY Step by step through Mayday and Pan-Pan radio calls – with GPS position, boat name, MMSI, persons on board and type of emergency. Read aloud on demand, NATO phonetic alphabet built in. 🧭 NAVIGATION & SAILING • Compass & GPS – heading, position, speed • OpenSeaMap – nautical chart; tap buoys, lights and wrecks for details • Navigation calculator – course, leeway, current triangle, ETA • Wind triangle, VMG calculator and laylines • Sail trim – simulator, telltales and trim recommendations • Anchor calculator – rode length and scope • Wind and unit converters • DWD weather charts • NMEA 2000 reader for your WiFi gateway • Notepad – stored only on your device 📖 NAUTICAL DICTIONARY 500+ sailing terms in 8 languages – English, German, French, Italian, Spanish, Dutch, Croatian and Greek. Search in any language, 13 topics, with pronunciation, fully offline. Perfect for chartering abroad. 🎲 OFF WATCH Six offline mini games for quiet hours: Berthing, Dinghy Slalom, Regatta, Wave Rider, Man Overboard and Stow the Stores. Lookout comes first – the game pauses as soon as you leave the app. 🛥️ BOAT MANAGEMENT • Tasks – plan and check off maintenance, with photos • Logbook – voyage entries with position and course • Checklists – one-time, recurring or seasonal • Equipment – devices, manuals, maintenance schedules • Inventory – equipment and spare parts with photos • Medical kit – expiry dates, minimum stock, storage location, PDF export • Expenses – track costs, photograph receipts • Documents – boat papers and manuals, available offline 📡 LIVE DATA & VOYAGES (SIGNAL K) Connect your boat's Signal K server and see it from anywhere: position, speed, wind, depth, temperature, pressure and battery – with history and trends. ClearShip turns the track into voyages with legs and stops, exportable as GPX. Included in the Skipper and Profi plans. 📶 OFFLINE-FIRST & SYNC Tools work offline, pinned documents are stored locally, and data syncs once you are back in range. A free account syncs boats, tasks and logbook across your devices and clearship.app. All tools also work without an account. 🌍 English and German, light and dark mode. Note: The anchor alarm uses your location in the background while it is active. ClearShip is an aid on board – it does not replace a proper anchor watch, official nautical charts or good seamanship. The medical kit is an inventory and gives no medical advice.
