Hi Laurent, to view the Marinetraffic data collected from volunteer AIS
receiving stations you will need an internet connection (e.g. via Wifi or 3G
- but these only work within limited areas and near land, you would need a
satellite internet connection further out) and suitable display device (e.g.
Android/iPhone or computer - laptop/notebook etc).
You could view AIS traffic near to your boat by receiving it directly (e.g.
Marine band antenna + AIS receiver + computer) - there's lots of options
available to choose from - just Google "AIS receiver".
