Skippers Log is your digital logbook for your yacht. Everything you can do in a good old fashioned paper logbook you can do here: - Create multiple trips for multiple ships - Record daily navigational data and weather observations - Include navigational live data from a wireless NMEA server - Automatic log entries based on the specifications you make (course change, wind change, ...) - Plot your trip on Apple map or Navionics map (active Navionics subscription required) - Print your trip with maps as a PDF - Create crew lists and print them - AIS targets shown on map (data from AIS receiver required) - Synchronize between you devices through iCloud - Display various data fields from NMEA data as overlay on your map - Fuel, water, cooking gas and outboard fuel consumption can be recorded - Take and add pictures to any day in the logbook (Premium version only) - Automatic geotag your position like e.g. "1.6 nm NW of Cape Finisterre" - Automatic download GMDSS and DWD weather forecasts (Euriope only, premium only) - Handling daily checklist (premium only) The free version of this app is limited to 1 ship, 1 trip and 40 manual log entries. Enough for a one or two week charter trip. No NMEA data are processed in the free app. In app purchase for the premium version and a 14-day free trial of the premium version. Please note, that the app will principally run on WiFi only iPads, but it is quite limited on these devices. Even if you use NMEA as your location source, automatic logging and track recording will likely reliably only happen while the app is in the foreground. You can still do manual entries, of course. To unleash the full potential you need a device with a gps receiver. Icons by Icons8
