Martha’s Vineyard (IX‑97) was built as a motor yacht by the Charles L. Seabury Co., Consolidated, New York, N.Y., in 1911; acquired by the Navy under the name Thelma from George A. Miller, Jr., New London, Conn., 11 January 1943; renamed Martha’s Vineyard 23 January 1943; converted by Brewer’s Drydock Co., Staten Island, N.Y.; and placed in service 30 March 1943, Lt. William W. Boyton, USNR, in command.
Assigned to the 3d Naval District, Martha’s Vineyard departed New York Navy Yard, New York, N.Y., 4 April for New London, Conn., arriving the same day. Two days later Navy and civilian scientists from the Underwater Sound Laboratory, New London, embarked to cruise Long Island Sound until the 12th testing new sound equipment. She spent the next 3 years in similar test operations along the New England coast interspersed with training exercises off Newport, R.I.
On 18 April 1946 Martha’s Vineyard decommissioned and was stripped at New York Naval Shipyard before she was delivered 6 September of that year to WSA for return to her owner.
