Sailing Log is a focused, offline logbook built by sailors, for sailors — your ship's log, crew, costs and damage protocol in one pocket app. Whether you're chartering for a week in the Med, skippering a flotilla, running a delivery or owning your own boat, Sailing Log turns every trip into the clean documents your charter company, your crew and your insurer actually want. No account, no analytics, no subscription. SHIP'S LOG • One-tap LOG POSITION NOW captures GPS, time, course (COG), speed (SOG) and a best-effort bay name from OpenStreetMap. • Add wind, weather, sea state, visibility, propulsion (sail / motor / motorsailing / anchored / moored / drifting) and free notes. • Live track map shows your route as it grows, with start/latest markers and every saved spot. TRIPS, VESSEL & CREW • Set up each trip with vessel name, model, call sign, registration, LOA, beam, draft, year, berths, engine, base harbour, sailing area, charter price and itemised extras. • Up to 3 vessel photos with a swipeable carousel. • Pick a Skipper with one tap — everyone else is crew automatically. • Reuse names from previous trips; new member auto-prefills the surname (perfect for families). • Skipper carries boat and radio licence numbers. SPOTS & ANCHORAGES • Save a spot with one tap — auto-identifies the cove, bay or beach. • Stays of more than an hour are detected from logged positions and offered as suggested spots. COSTS & COST-SPLITTING • Log every expense (food, marina, fuel, parking, tolls, repairs…). • Mark each cost Shared (split equally) or Individual. • Optional groups (families / cabins) — settle by member or by group. • Settlement engine shows the minimal "who pays whom" transfers so everyone ends up equal. CHECK-IN / CHECK-OUT & DAMAGE PROTOCOL • Standard 24-item boat checklist for both check-in and check-out. • Report damaged or missing items with location, note and up to 3 photos, all auto-timestamped. • Export a Damage Protocol PDF or email it straight to the charter company with vessel and charter details on top. BEAUTIFUL EXPORTS • Logbook PDF with offline route map, vessel, crew, costs, full position log and saved spots. • Logbook Excel (XLSX) with title banner, bold headers, borders, zebra rows, column widths and auto-filter. • Cost-split PDF and XLSX with expenses, balances and settlement list. • Share to Files, AirDrop, Mail, Messages, or email PDF + XLSX in one tap. ON-BOARD TOOLS • Weather forecast (Open-Meteo) with wind-arrow map, 48-hour hourly strip, and automatic alarms for storms, gusts and rapid pressure drops on the active trip. • Anchor watch with adjustable swing radius — vibration, alarm and high-priority notification if the boat drifts outside the circle, even with the screen off. • Nautical reference: signal flags, phonetic alphabet, IALA buoys, light characteristics and sound signals — all offline. • Safety briefing with a per-crew sign-off list. PERFECT FOR Charter skippers who need a clean handover document. Owners who want a real ship's log. Sailing schools keeping uniform records. Crews splitting marina, food and fuel without spreadsheet drama.
