The track for Nancy was recorded by Jibeset in real time using a SPOT Trace device on Nancy set up to provide track points every 5 minutes. From time to time the SPOT device fails to provide data – why is being investigated. This results in an incomplete track for Nancy.

Tracks can also be recorded in real time from Delorme devices.

The tracks for other boats were recorded on a GPS device and uploaded after the race.
