How to contribute AIS data?
Using ShipPlotter
If you would like to contribute AIS data from ShipPlotter, click on Options->Sharing->Server and set:
- Server: www.aisliverpool.org.uk
- Port: 80
- Script: shipinfo.php
The 'forward data from server 1 to server 2' box should not be ticked if you are sharing with the COAA server. Please only upload your own AIS data to AISLiverpool.
AISLiverpool is an "upload only" server so the "upload only" and "Trust static info" options have no effect.

Alternatively, you can directly upload to ShipAIS.com:
- Server: www.shipais.com
- Port: 80
- Script: shipinfo.php
Raw AIS NMEA or AIVDM data
If you are not using ShipPlotter, you can also upload unprocessed AIS data to
- www.aisliverpool.org.uk (62.49.29.217)
- Port: 4000
- UDP data
