One of John’s daily tasks (tracked on Triton Administrator) is to check email traffic on the vessel’s exchange server.

I have been working with Great Circle Systems since 2006 when they did the installation of all our networking and Internet communications equipment on our boat being built in Germany.


The equipment they recommended and installed was exactly as we required.  We have had extremely good results with all of their equipment and it has performed as they had advised.
