Towed? So structurally sound but mechanically dubious?
I took the SS US to Europe. Prior to boarding I had a dental procedure that knocked me on my can for four days (at sea). I woke up and we were in Southhampton. I mean it could travel, and fast. They say it served good chow. I never learned.
I believe the engines are removed and the twin brass screws were on the stern deck. many years ago.
