Jim of sy Tenaya has started sending in tracks from her cruise up the Queensland coast. This is really interesting as it is the start of a controlled assessment of iNavX's usefulness as a track recording device. Very promising indeed.
Also from Simon of Aequus there may be the possibility of Louisiades tracks recorded by Software On Board. These tracks appear at present as screen shots on his excellent Friends of the Louisiades site. http://www.louisiades.net/
