LogBook — Digital Yacht Log

LogBook — the digital yacht logbook that produces documents professionals actually use.

Built for skippers, charter operators and delivery crews who need a fast, reliable alternative to paper logbooks that get wet, lost and illegible.

LOG A POSITION IN ONE TAP
Quick fix captures your GPS position, distance run since the last entry, course and speed over ground, and current wind and pressure. Choose sailing, motoring, anchored or moored, add a note — done. The full entry adds sea state, visibility, engine hours, fuel and sail configuration when you need them.

WORKS WITHOUT SIGNAL
No coverage offshore? Entries are saved on your phone and sync automatically when you're back online. Nothing gets lost.

WATCH REMINDERS THAT KNOW YOU'RE MOORED
Optional reminders prompt you to log while under way. With GPS track on, they only fire once the boat has actually moved — a night in the marina stays quiet.

BUILT FOR THE COCKPIT
An instrument-style display that stays readable in sunlight. Day and dark themes follow your phone, and a red-only night mode preserves your night vision on watch. Positions in degrees and decimal minutes, times in UTC.

PROFESSIONAL PDF VOYAGE REPORTS
A voyage summary with route plot, a ship's log laid out by day, and a crew manifest with signature block. Every page is numbered and carries a document ID. Hand it to a charter client or a port authority — it looks like a maritime document, not a database printout. CSV export included.

TRACKS, MAPS & SAILING ATLAS
Optional background GPS track records your route and uses almost no battery while you're moored. See every voyage on a map, then zoom out to the Sailing Atlas: everywhere you've sailed, on one chart.

SEARCH YOUR WHOLE LOGBOOK
Find any entry by port, note or date across all voyages. Filter by sailing, motoring, in port, or Beaufort 5+ and 7+.

CREW & VESSELS
Crew lists with role, nationality, date of birth, passport and emergency contacts — passport numbers and medical notes are encrypted on our servers. Save your vessels once and reuse them on every voyage. Vessel owner and skipper are recorded separately, as charter work requires.

DETAILS THAT MATTER
— Beaufort force calculated from wind speed
— Weather auto-fill from current conditions
— Cumulative distance across all entries
— Units: nm/km, knots/km/h, °C/°F
