  ## Construction
  
  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.

  ## Spaulding yacht
  
  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.
  
  ## Coast and Geodetic Survey career, 1915–1917
  
  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.
  
  She operated along the United States East Coast, used by Ernest Lester Jones—Director of the Coast and Geodetic Survey from 1915 to 1929—to ferry dignitaries about in addition to her hydrographic survey work.
  
  On more than once occasion, Isis assisted mariners in distress. On 28 April 1916, she assisted the launch North Star, which was swamping because of being overloaded in a light choppy sea, in Charleston Harbor off Charleston, South Carolina. On 18 February 1917, she aided to the yacht Soncy at Savannah, Georgia, during a fire on the waterfront. 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.
  
  ## United States Navy career, 1917–1919
  
  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. Rude in command. After a minor overhaul, Isis commenced duty as the flagship for the Commander of Squadron 2 Cruiser Force, on 13 November 1917, at Staten Island, New York. She served in that capacity until 14 June 1918, and remained in the New York area until December when she arrived at Naval Station Norfolk. Following operations at Norfolk, she was decommissioned on 30 April 1919 and was returned to the Coast and Geodetic Survey.

  Once again USC&GS Isis, she resumed her survey work along the U.S. East Coast. On 20 January 1920 she sank off Crescent Beach, Florida, after striking a submerged obstruction while taking soundings of the sunken dredge Florida to mark the wreck as a navigational hazard.
