USC&GS Isis  USC&GS "Isis" was a survey ship that served in the United States Coast and Geodetic Survey from 1915 to 1917 and from 1919 to 1920. "Isis" was built as a private yacht of the same name for William S. and John T. Spaulding of Boston, Massachusetts, by Marvel's Yard at Newburgh, New York and launched on 10 December 1901. She was fitted out at Fletcher's Shipyard at Hoboken, New Jersey, and completed in 1902. "Isis" was a steel steamer, 377 gross tons, 256 net tons, with a length of 180.4 feet, beam of 24.8 feet and 11.7 foot draft. She had an indicated horsepower of 2,000 for a speed of 16 knots with capacity for 120 tons of coal with a complement of eight officers and forty-four men. "Isis" was assigned the official number 100758 and the signal letters KRNJ. The Spaulding family home was at 99 Beacon Street in Boston but the country estate, Sunset Rock, at Prides Crossing overlooked the anchorage for the family yacht. John Spaulding steamed to the city several times a week. "Isis" also cruised the Mediterranean and Adriatic. The Coast and Geodetic Survey acquired her from her owners on 1 July 1915 and placed her in service as a survey ship that year.

On 28 April 1917, her officers and crew helped to put out a fire on the steam schooner "Rosalie Mahoney" in the St. Johns River in Florida. On 24 September 1917, "Isis" was transferred to the United States Navy for World War I service as the patrol vessel USS "Isis"  She was commissioned on 4 October 1917 with Lt. Gilbert T.
