Skippers Log

- New: polar diagram. While under way SkippersLog continuously records wind and speed data and builds a performance polar for your boat — speed through the water by wind angle and wind speed, separated by sail configuration. Available under Settings/Polar diagram; see the help there. - Bathymetry: fixed jagged (sawtooth) depth contours on closely parallel tracks. The lateral corridor widening no longer fabricates conflicting depths where real soundings from another pass already exist. - Fixed an app hang at launch on some devices/connections where the map service initialisation could block the app before it became responsive. - General stability improvements for iCloud sync. - Significantly improved device GPS position tracking, especially at low boat speed: occasional wrong fixes (e.g. Wi-Fi/cell-based positioning instead of GPS) are now detected and rejected, a position occasionally frozen by iOS is automatically detected and recovered, and the speed reading stays stable at slow speeds instead of intermittently dropping to 0. - Fixed a possible crash in the NMEA log view (Settings/NMEA) that could occur with a long-running, large log. Previosuly fixed in 1.9.1: - Fixed a crash when adding or deleting a sail while an input field was being edited. - Fixed a crash when displaying the map with an invalid position or zoom level.

- There is now a bathymetry module that records the depth data provided via NMEA and displays it on the map, comparable to the Sonar Live Chart view in the Navionics/Garmin app. See Settings/Bathymetry and the help there. Your own measurements can be exported and imported. - Positions of AIS targets are now dead-reckoned between signal transmissions using the last course vector and speed, and shown as a hollow symbol on the map. This can be turned off in the map settings. - The app can now also be installed and run on an Apple Silicon Mac. Please note that certain functions are not available on the Mac because the hardware is not present there (GPS, barometer). Position data can therefore only be obtained via NMEA. - Fixed an error, among others when printing the PDF log, when no internet connection was available for generating the map.
