I just found this diary of all the AirNav annnouncements about the Shiptrax release. Makes interesting reading. Makes me wonder if it will ever be released. It's already 2 years behind schedule.
It is worse than that Harry.
It is more than 3 years late.
If you follow the Shiptrax forum you will see the first announcement was in 2007. Then a proposed ship date was March 2008.
At first it was software only. Then it became software and hardware.
The price went from 500 Euros to 59 Euros.
The software has been variously 99% complete; 90% complete, pick any number% complete.
The stage has been reached where there seems little point in it.
I use MarineTraffic, even when I am sat on the beach at Calshot, getting data via a mobile phone internet connection.
