Sultana commissioned for Trenor Luther Park and his wife Julia Hunt Catlin, of New York City.
After his death in 1907, the yacht was sold to Mrs. E. H. Harriman of New York City who loaned the steam yacht to the United States Navy under a free lease for war service.
The yacht was commissioned on 27 May 1917, with Lt. E. G. Allen in command.
From 4 July 1917 to 5 December 1918, Sultana was attached to the United States Patrol Squadron based at Brest in France and performed escort and patrol duty.
After the war she was stripped of her military hardware, decommissioned, and returned to Mrs. Harriman on 17 February 1919 and struck from the Navy list.
If you have any information on either of these two yachts please can you let me know.
