Aquamarine was built in 1925 by Pusey and Jones Corporation, Wilmington, Delaware under the name Siele, the private yacht of John H. French. In 1936 she was sold to Robert H. Wolfe, of Columbus, Ohio, and renamed Seawolf. Seawolf was bought by the Navy on 13 January 1941, and commissioned on 9 April 1941, Lieutenant G. A. Lange in command. She was named for the gemstone aquamarine.
Assigned to the Naval Research Laboratory, Bellevue, D.C., Aquamarine assisted in experimental work, chiefly underwater sound. Although most of her experiments were conducted on the Potomac River and Chesapeake Bay, she also operated off New London, Connecticut, from 16 October to 4 November 1943, and off the Florida coast and in the Bahamas from 24 January 1944 to 18 April 1945. During 1945 and 1946 Aquamarine had additional duty as special tender to the presidential yachts Potomac and Williamsburg.
Aquamarine was decommissioned on 21 June 1946 and transferred to the Maritime Commission on 31 January 1947 for disposal.
Private ownership, 1947–2008
She was sold to Colonel E. M. Grimm of Columbus, Ohio, in 1947, and her name changed back to Seawolf. She was sold in 1954 to Ennolls A. Stephens of Irvington, Virginia, owner of The Tides Inn, Irvington, and renamed Miss Ann.
In 2008, Miss Ann was sold to private interests who placed her in Charter Service on the Potomac River. In 2014, she is located at the Colonial Beach Yacht Club in Colonial Beach, Virginia.
