The second USS Itasca (SP-810), later USS SP-810, was a United States Navy patrol vessel in commission from 1917 to 1919 which was employed as a hospital boat. Itasca was built as a private wooden motorboat of the same name in 1908 by the Stamford Motor Construction Company at Stamford, Connecticut. In 1917, the U.S. Navy leased her from her owner, Henry Henke, for use as a section patrol boat during World War I. Sources differ on her commissioning date, claiming both that the Navy took control of her from Henke at Norfolk, Virginia, on 10 August 1917 and commissioned her as USS Itasca (SP-810) on 18 August 1918, and that she was commissioned in July 1917.
