Or go to your Apps store and download PredictWind Tracker, a bit of familiarisation with how the tracker works (best gained off your Mac or PC), and you are away.
The system is very suitable for coastal races an uses a smartphone on the race boat, which has been setup with the PredictWind Tracker app.
Fans can also follow progress in the race with the same application.
The PredictWind Tracker runs off 3G mobile technology, running through about 2MB of data per 24hr period. 'Most yacht races can't afford to run satellite race tracking, so this is idea says PredictWind founder, Jon Bilger.
The application is free to yacht clubs. If the yacht enters an area where there is no 3G coverage then the data is stored in the phone and transmits when the yacht does re-enter 3G coverage
