Importing Boat Log Data

How to load boat log files into Njord Analytics

Supported Boat Data Log File Formats

Data Source Notes
Adrena (TRZ, CSV) Reads TRZ files or CSV (French CSV headers).
Anemomind (CSV)
Bravo (TXT)

Reads Instruments.txt/Performance.txt files, or data exported from RaceCutter. Also, reads starts from StartFeatures files.

Deckman (LOG)

Reads Deckman CSV files.

Deckman may save data from multiple days into one file. For best results, make sure to only export data from one day.

Note: The date format needs to be dd/mm/yy or dd/mm/yyyy or yyyy-mm-dd, not mm/dd/yy.

Also reads polars in Deckman format, and Deckman start files (D).

Expedition (CSV)

Reads Expedition CSV files – either standard CSV files written to disk by Expedition, or files exported using Expedition's extract feature (to select exported columns) - when using the extract feature, the format needs to be set to "CSV".

In particular, supports reading time to gun, and the port, starboard and mark coordinates to automatically populate race information.

Reads comments and sail change information from Expedition event files (TXT), which can be loaded alongside the main log file.

Reads polars in Expedition format (TXT).

Expedition mark files may be loaded when entering the race course in Njord Analytics, to help with coordinate input.

FaRo (CSV) Reads FaRo CSV files.
Garmin (FIT) Includes support for heart rate data.
GPX Reads Lat/Lon data. COG and SOG are calculated from Lat/Lon data.
Helmsmart (CSV)
KML

Reads Lat/Lon data. COG and SOG are calculated from Lat/Lon data.

Note: Not all KML files will work. The KML file needs to contain Placemark elements, with Point and Timestamp sub-elements. Track polylines without time information will not work.

Reads comments and sail change information, which can be loaded alongside the main log file.
