It started in the Cyclades — anchored in a southerly gale, trying to remember if the port engine impeller was last changed in Paros or Leros. After 8 years at sea, I built what I needed.
Your Transit Log expires in 47 days. Do you know that?
The paperwork for non-EU boats in Greece alone can sink your season.
The Schengen 180-day window has caught out sailors who thought they were fine.
The rolling window is brutal. Most apps don't even know it exists.
Your maintenance log lives in three notebooks, a WhatsApp thread, and someone's memory.
Good luck finding the last impeller replacement date.
Every boat manager app you've tried was built by someone who has never sailed.
Generic tools for weekend boaters. Nothing built for real bluewater cruisers.
Take a photo of your insurance certificate. Your maintenance log. A Victron device label. A box of pasta. AI reads it and imports it into the right place — automatically.
No copy-pasting. No broken CSV imports. No reformatting spreadsheets at midnight in an anchorage with no WiFi.
Every tab covers something real — built from years of liveaboard sailing, not a product manager's wishlist.
Non-EU boats in Greece juggle Transit Log validity, eTEPAY payments, and the Schengen 90/180-day rolling window simultaneously. Miss one date and it costs thousands. The Clearance tab shows every countdown on one screen — green, amber, or red. No spreadsheet hunting the night before you check in.
Track port and starboard engine hours separately. Every service item — engine oil, gear oil, fuel filters, lip seals — gets its own gauge showing exactly how many hours remain before the next change. Time-based tasks like coolant flushes show a day countdown alongside the hour-based ones. You'll never pull into a boatyard having to say "I think it was due around…"
Build your provisioning inventory by category — food, drinks, toiletries, and more. A shopping list shows exactly what needs restocking. Check off items as you shop; your crew sees updates in real time without a phone call. History and insights tabs show what you've stocked before, so reprovisioning for a long passage takes minutes, not an afternoon.
Catalog every spare by manufacturer part number, quantity, storage location, and cost paid. Filter by system — Yanmar engine, saildrive, watermaker, electrical. Adjust stock counts with a tap. When a part drops low it flags red, so you order before the next crossing — not after you've already left the last chandlery three weeks behind you.
Log every installed system — electrical, mechanical, sails, rigging — with full specs: model numbers, wiring notes, install dates, prices paid, and exact location on board. When a contractor asks what shunt you're running with the LiFePO4 bank, or a surveyor wants the sail inventory, you pull it up in seconds instead of digging through a folder of receipts.
Track every bottle on board by size and log refills as you go. The dashboard shows total kilograms remaining, how many bottles are full, and a running price history — lowest, average, and highest cost per kilogram across every port you've ever filled in. Useful for comparing marina prices between countries, and for knowing if you'll make it to the next port without running dry mid-passage.
Log your current hourmeter reading and the reading at your last filter change. The gauge calculates hours remaining to the next membrane service automatically — no mental arithmetic, no sticky note on the nav table. A separate charcoal filter tracker runs on a 6-month calendar interval, so you know when it's due even if the watermaker hasn't been used much since the last crossing.
A full seasonal checklist organised into sections — general tasks, engine, rig, systems — with 58 items for Winter 2025/26 and counting. Reset each spring and start fresh for the new season. Add custom tasks specific to your boat. Work through the list anchored in the boatyard or hand it off to your yard manager so nothing gets missed while you're not there.
The AI Import Assistant lives here — take a photo of any document or paste text and it maps the data to the right tab automatically. Choose exactly which tabs appear and drag them into the order that makes sense for how you sail. Cloud sync keeps every device current. Backup and restore any time, or import from JSON if you're migrating from a spreadsheet.

No App Store. No install. Add it to your home screen in three taps — it opens full-screen with its own icon, indistinguishable from any app you've downloaded.
Must use Safari — Chrome on iPhone does not support home screen install.
Works on Samsung Internet and other Android browsers too — Chrome is most reliable.
"How many hours on a saildrive lip seal? I knew it was in the manual somewhere. And when did I last replace it? Written down somewhere — a notebook, a spreadsheet, a WhatsApp message to myself, or maybe just in my head. Anchored in the Cyclades in a southerly gale, I spent twenty minutes looking across four different places before I found the answer. That's when I decided to build something better."
