Position, speed, course, wind, barometer, and what the sea was doing. The discipline of the hourly log entry is as old as passage-making, and it is still what saves you when the chartplotter dies.
WatchKeeper’s logbook is built for the way entries actually happen: one thumb, mid-watch, boat moving. Position comes from the phone, the sails you are flying come from your inventory, and the passage mode (sailing, motoring, anchored) is sticky so a quick fix never rewrites the day. Offline first, always: entries queue on board and sync when the signal returns, with zero data loss.
And it stays yours. Every completed passage lives in the archive with full-text search across every logbook you have ever kept, and one-click export to CSV, PDF, plain text, or markdown. Type "squall" and find the night it found you.
- One-thumb entries: position, SOG, COG, wind, baro, notes
- Offline-first: log with no signal, sync when it returns
- Sticky passage mode: sailing, motoring, or anchored, never lost
- Sail tracking: the exact sails flying, hours per sail
- Past logbooks: every passage archived, searchable end to end
- Exports: CSV, PDF, text, markdown, or the whole fleet as a zip
Your data walks away with you. Every logbook exports in four formats. A paper logbook can outlive the boat; this one can outlive anything.
Miles astern at sunset. Every one of them written down.
WatchKeeper is a passage log and shore-crew briefing tool for sailors who take the ocean seriously. One tool for the logbook, the AI shore briefs, the safety locker, the crew records, and the boat itself, built and dogfooded on a real ocean crossing aboard SV Cloud Nine.
Guides for everything live at support.watchkeeper.me, and every boat gets a free public Ship’s Blog the family can follow.
