Missing Steam Ship

I'm getting really confused at the moment, I'm sure I found a web site ages ago that listed the "Prince William" as one of the Steam Packet vessels yet now cannot find the site nor can I find this ship in the list of vessels on the Steam Packet site. I thought I had found it's history and that it was one of the ships requisitioned by the Admiralty for War service but now I begining to wonder whether I confused it with another ship! Can someone put me out of my misery please?
