SS Ancon was an American
steamship that became the first ship to officially transit the
Panama Canal in 1914. The steamer began life as the SS
Shawmut, built for the Boston Steamship Line in 1902.
About 1910 she was purchased by the
Panama Railroad Company to provide shipping required for the construction of the
Panama Canal. The name was changed to
Ancon after
Ancon Hill and
Ancon township in
Panama, home to the head of the Canal Commission.
Ancon and her sister ship Cristobal played a crucial role in building the canal, bringing workers and supplies, notably massive amounts of cement, from New York to Panama for the construction project.
On August 15, 1914 Ancon made the first official transit of the canal as part the canal's opening ceremonies. (Her sister ship Cristobal had made the first unofficial transit on August 3, delivering a load of cement, while an old French crane boat Alexandre La Valley had crossed the canal from the Atlantic in stages during construction, finally reaching the Pacific on January 7.)
The Panama Railroad Company replaced SS
Ancon in 1938 with a
second SS Ancon, a larger steam turbine cargo liner which later saw considerable action as US Navy Transport
USS Ancon in
World War II.
