Soon after the United States entered World War I, Actus — a yacht constructed in 1907 at Neponset, Massachusetts, by George Lawley & Sons — was taken over by the US Navy as a section patrol craft from Mr. E. B. Dane; commissioned on 1 April 1917, with Ensign H. A. D. Cameron, USNR, in command; and, on 26 May 1917, over a month later, formally purchased by the Government. Wikipedia
