context_page_description: USS Hyac (SP-216) was a United States Navy patrol vessel in commission from 1917 to 1918.
  Hyac was built as a civilian motorboat of the same name in 1915 by the Weckler Boat Company at Chicago, Illinois. The U.S. Navy acquired her from her owner, W. M. Derby of Chicago, in 1917 for World War I service as a patrol vessel. She was commissioned as USS Hyac (SP-216) on 5 July 1917 with Lieutenant W. M. Derby in command.
  Based at Chicago and assigned to the "9th, 10th, and 11th Naval Districts"—at the time a single administrative entity made up of the 9th Naval District, 10th Naval District, and 11th Naval District -- Hyac served as a patrol boat on the Great Lakes between Chicago and Sault Ste. Marie, Michigan, during World War I.
  Following the end of the war, Hyac was returned to her owner on 26 November 1918.
