Cruise ship tracker, historical?

[pdmlynek]

I am trying to find a ship tracker, more specifically, cruise ship tracker. 

 

Although I am successful in finding many trackers that tell me where ships are currently (e.g., https://www.marinetraffic.com/ , https://www.vesselfinder.com/ ,  https://www.myshiptracking.com/ , https://www.shiplocation.com/ , etc.), and there are plenty of sites that will tell you where cruise ships are scheduled to be, I am having difficulty finding out where ship (particularly cruise ships) were a month, a year or a decade ago.  There are several paid websites where you can get that info, or services that will search this, but I'd like to see if there are free, easily accessible historical data sites.  Surely, that data should be readily accessible, no?

 

Thank you in advance!
