SS Delphine (1921)

SS Delphine is a steam yacht launched in 1921. During the Second World War, the yacht was used by the US Navy, as the gunboat USS Dauntless (PG-61).

Power was originally supplied from three Babcock & Wilcox boilers^[2] powering two 1,500-horsepower (1,100 kW) quadruple-expansion engines.^[1]

In her 2003 refit Delphine was re-equipped with two modern water-tube boilers operating at 20 bars (290 psi), the larger of which has an evaporation capacity of 14 metric tons (31,000 lb) of steam per hour while the smaller can evaporate 4 metric tons (8,800 lb) per hour;^[3] these new boilers supply the original quadruple-expansion engines. "Of all the large American-built steam yachts built between 1893 and 1930, the Delphine is the only one left in her original condition with her original steam engines still in service."^[1]

The Delphine was commissioned by Horace E. Dodge, co-founder of Dodge Brothers (though he would never saw her complete, having died from the Spanish flu in 1920). The yacht was launched on 2 April 1921, captained by Arthur A. Archer.^[4]

The Delphine caught fire and sank in New York in 1926, only to be recovered after four months, restored and remodeled for 750,000ドル. By 1935, she was docked for an extended period at her private pier on Lake St. Clair. She suffered further damage in 1940 when she ran aground in the Great Lakes, and was repaired.

The Delphine was acquired by the United States Navy in January 1942, refitted as a gunboat with a wartime paint scheme, a pair of 3-inch guns, six .50 cal machine guns, and a Marine detachment. She was commissioned five months later, rechristened as the USS Dauntless (PG-61), to serve as the flagship for Admiral Ernest King, Commander in Chief of the U.S. Fleet and Chief of Naval Operations. She was sold back to Anna Dodge (Horace Dodge's wife) after the conclusion of World War II and restored to civilian standards and service, including her original name.^[2]

Purportedly, U.S. President Franklin D. Roosevelt used the yacht and the Yalta accords were drafted while he was on board.^[5]

Delphine was sold in 1967 and again in 1968, changing names again to Dauntless, only to be sold again in 1986, 1989, and in 1997 – at scrap metal prices to her next owner, Jacques Bruynooghe, who proceeded to restore her for 60ドル million to the original 1921 condition including interior decor and the original steam engines.^[1] She was rechristened Delphine by Princess Stéphanie of Monaco on 10 September 2003. In 2007, the ship was used as part of the setting for the Rian Johnson film The Brothers Bloom .^[6]
