About the satellite tracking
Boats will be shown on the Fleet Viewer when the satellite trackers are fitted to the boats - from just before the start until just after they finish.  The trackers will show the boats' positions every six hours.
We always try to ensure that the satellite trackers are installed correctly, but sometimes they may fail to send a position at the right time.  This means the position data for that boat can't be updated, but it should be captured at the next six hour update.
