Hi.. Glad you liked our present listing.
No, there is nothing to pay, it is all run and shared by enthusiastic volontairs from a central server in the UK.
All shipplotter members can see all vessel movements in
each others areas by sharing over the internet
. In this case
many more areas are available.
Our listing is based on self-creative maps from Google
which we feed actual AIS data received from our local AIS receivers.
I was watching the big marinas
in Cannes and Monaco today and although winter and little movements, many of the large yachts have their AIS transponders working.
