I found a new website where you can locate a given cruise ship and read off precise, real time location, wind speed, air temps, wave heights, and much more. Go to:
www.sailwx.info/shiptrack/shiplocations.phtml
click on shiptracker
click on cruise ship tracker
choose Island Princess (for example)
go to "plot position of ship with call sign" ie ZCDG4 for Island Princess
click search
All of this information will be shown on your screen. Amazing!
