Looks like the ship was renamed, it was an oil tanker:
"SS The Cabins renamed William T. Steele" http://www.marylandsilver.com/title26.htmhttp://www.marylandsilver.com/books9.htm
History of the ship:http://www.t2tanker.org/display-tankers-test.php?t2table=ala...
Picture of a same type tanker:http://en.wikipedia.org/wiki/T2_tanker
also click on link at bottom of List of names and The Cabins is in the T section.
You might try the SIU-Seafarers International Union to see if they have an archive and any old records of members. They had the strike in 1947. http://www.seafarers.org/aboutthesiu/phrem.asp
