  • Launched 12 August 1944 and sponsored by Mrs. Anastasia Carborwoski
  • It was customary for L. D. Smith to launch all of its vessels on a Saturday so that all the towns people could attend and the high school band could play during the event. Most ships are launched by
    breaking a bottle of champagne over the bow but because Wisconsin is the Dairy State they used a bottle of milk
