USS Druid (SP-321) was a private yacht launched 10 February 1902 as Rheclair that was built for Daniel G. Reid. Reid sold the yacht to Senator Nelson W. Aldrich who renamed the yacht Nirvana only just over a year before his death. Aldrich's estate chartered Nirvana to John Wanamaker until it was bought by his son Rodman Wanamaker who used the yacht for cruising until a fire on 14 December 1916, just before a cruise south, severely damaged the vessel. He chartered an alternate vessel for his trip south and, after full repairs, the yacht was sold to Walter W. Dwyer who gave it the name Druid with intentions to sell the yacht to the government in order to finance a shipyard venture in Pensacola, Florida.
