Your digital logbook
Your boat provides the data. DiLog turns it into your logbook.
Logbook keeping, just a tedious obligation?
Many know it: During a tiring sailing day, you still have to enter positions, weather data, and engine hours into the logbook. Handwritten, illegible, incomplete.
But a well-maintained logbook holds so much more than just a tedious obligation: Like your perfect anchorage from last season, that night sail you love to remember, or the engine failure in 3-meter waves off Helgoland.
DiLog keeps your logbook. Automatically and seamlessly, while you simply enjoy your trip.
