A Century Ago, The S.S. Selma, A Concrete Ship is Launched.

"Built by F. F. Ley & Company in Mobile, Mobile County, the S.S. Selma launched on June 28, 1919, the same day World War I officially ended. It was subsequently sold by the government to a private company and entered service as an oil tanker servicing several ports on the Gulf Coast. Its service was cut short when it struck a jetty at Tampico, Mexico, on May 31, 1920, causing a 60-foot crack in its hull."

The S.S. Selma was stripped of equipment and intentionally sunk, though it remains visible even today, but there are new fears that the ship is going to sink below the surface in coming years.
