Don't worry - as long as your tracker is enabled in your Tracker List, any tracks recorded are saved. So you can just turn on your tracker and go sailing.
To see a track in the cloud player, you must create a race. Go to your race management console (Login and click the Setup button at the top of the TackTracker Cloud page.)
You can create the race at any time, before or even after your race session.
You can also retrieve any track you have recorded live into the TackTracker player for PC or Mac via the Track Loader. Use the Track Loader's Get button to bring up a track search wizard. Specify the date, time period and location for the tracks you wish to download from the cloud.
You can also use this Get feature to retrieve other people's tracks that you have been given access to.
