iPhone
New in v1.1: Voyage maps, Sailing Atlas, and a full statistics dashboard. Watch your GPS routes plotted on a map and track every mile across your sailing career.
LogBook — the digital logbook that produces documents professionals actually use.
Built for professional skippers, charter operators, and delivery captains who need a fast, reliable alternative to paper logbooks that get wet, lost, and illegible.
COMPLETE A DAILY LOG ENTRY IN UNDER 30 SECONDS
Date and time pre-filled. One tap for GPS position. Wind direction, speed, and Beaufort scale — done. Everything a compliant maritime log requires, without the friction.
PROFESSIONAL PDF VOYAGE REPORTS
Generate a beautifully formatted voyage report in seconds. Vessel details, skipper information, crew manifest, full log entry table with Beaufort badges, navigation data, and voyage summary. Hand it to a client at the end of a charter or submit it to a port authority — it looks like a purpose-designed maritime document, not a database printout.
VOYAGE MAPS & SAILING ATLAS
See your GPS track plotted on a map for every cruise. Then zoom out — the Sailing Atlas puts all your voyages on a single world map. Every port a dot. Every route a line. Your entire sailing career, charted.
FULL VOYAGE STATISTICS (PRO)
Track total distance sailed, days at sea, engine hours, and propulsion breakdown across your entire logbook history. Beaufort frequency, voyage history with distance bars, and a full analytics dashboard built for sailors who take their data seriously.
FULL CREW MANAGEMENT
Add unlimited crew members per voyage with full personal data — name, role, nationality, passport number, date of birth, and emergency contacts. Everything required for maritime authority compliance and charter documentation.
DESIGNED FOR PROFESSIONAL USE
— Log entries with position, wind, sea state, visibility, barometric pressure, engine hours, fuel consumption, and sail configuration
— Course over ground and speed over ground recorded per entry
— Beaufort scale calculated automatically from wind speed — never entered manually
— Cumulative distance tracked across all entries
— Vessel owner and skipper recorded separately — correct for charter operations
— CSV export alongside PDF for your own records
— Units configurable: nm/km, knots/km/h, °C/°F
FREE TIER — FULLY FUNCTIONAL
Log unlimited voyages, manage crew, and export PDF reports. Free PDFs include a tasteful footer watermark. Upgrade to Pro to remove it and unlock the premium layout.
PRO TIER
— Watermark-free PDF with vessel name on every page
— Custom header with charter company or skipper name
— Cloud backup and sync
— Full voyage statistics and analytics dashboard
— Sailing Atlas — all your voyages on one world map
LogBook is built for the professional sailing community. Every feature is filtered through one question: does a charter skipper need this on a real voyage?
