You can now upload a GPX file from within the app for a race if it

GPS device's own companion app, you can then upload the GPX files
from the Sailchart app (on the same day as the race).
-
Some Android devices do not obtain precise GPS position resulting
in unusable data. New options have been added to Prefs to allow
the user to experiment with different settings for Android
location accuracy.
-
You can now define races as having staggered handicap start times.
For each fleet you can specify the fleet's start time and then the
race analysis and playback will factor in the fleet's start time
for analysis and playback.

End of Season Report
Sailchart has now completed it's first season of racing with the
Salcombe Yawl fleet at Salcombe Yacht Club being the pioneers
testing this new application.
Over the course of the season, 100 races were tracked with up to 15
boats per race.
Feedback from the fleet is that many enjoyed the ability to replay
the race and use the analysis to help understand how they compare to
other boats in terms of distance sailed, VMG, tack performance and
course selection.
At first the tracking data was gathered using the Sailchart app, but
standalone GPS trackers were introduced in August to allow tracking
where sailors did not want to have a smartphone on board.
