  ## Service history
  
  The second ship to be so named by the U.S. Navy, Mariner, a 234 long tons (238 t) steam tug, was built at Camden, New Jersey, in 1906. Following America’s entry into World War I, she was taken over by the Navy and commissioned 1 February 1918. She was employed by the Panama Canal Commission during the construction of the Panama Canal and after its completion. Mariner patrolled the approaches to the canal and provided tug and towing services during the remainder of World War I. She was returned to her owner 13 January 1919 and resumed her civilian work. Her name was struck from the Navy list. Mariner's ultimate fate is unknown.
