[aprssig] Cruise Ships, APRS.FI, and AIS

AFIK APRS.fi has always had ship tracking facilities.

I have a friend who works for Carnival Cruises, and is also a ham
licence holder.  He has taken a 2m handie on a couple of ocasions for
his own use, no problem afik.

On his first trip, they could also use the ship's onboard wifi with no
restrictions, so skype calls home were no problem.  Subsiquent trips
though, just about any internet traffic that would need to go "off ship"
was blocked, unless you paid a large fee for a poor service, even as
staff/crew.

Perhaps someone got a satelite internet bill, and had to pay for dozens
of laptops doing automatic updates as well as all the voip calls
perhaps?...   The ships have their own webservers, but the content is
limited and not that interesting he says.

However, he found in some places, there were genuinly free wifi nodes
reachable from the ship when in dock.

Take a good pair of binoculars, in the absence of hand held AIS RX.

Enjoy the trip.
