What this boat is
SS Delphine is a one-off American steam yacht built in 1921, combining original quadruple-expansion machinery with restored period interiors and extensive guest facilities. At approximately 78.5 metres, she offers a distinctly different experience from a modern diesel superyacht: formal entertaining, sheltered promenade decks and leisurely cruising, supported by a substantial professional crew. Her current charter offering accommodates 12 guests.
The model in detail
Launched on 2 April 1921, SS Delphine was built by Great Lakes Engineering Works at River Rouge, Michigan, for automotive industrialist Horace Dodge. She is an individual commission, not a production model. Gielow & Orr designed her exterior and contributed naval architecture, with Antoine Wille also credited for naval architecture. Tiffany’s of New York supplied the original interior design, establishing the decorative character subsequently recreated during restoration.
Her displacement hull is steel, with an aluminium superstructure and a beam of 10.82 metres. Guest spaces extend from the main deck to sheltered promenade areas and an upper boat deck. The historical accommodation plan placed two principal suites on the main deck and additional guest cabins below. A formal dining room, music lounge with a Steinway piano and separate smoking room provide distinct reception spaces rather than one continuous contemporary saloon.
Propulsion remains her defining feature: two original quadruple-expansion reciprocating steam engines, each rated at 1,500 horsepower, drive twin propellers. Restoration-era technical documentation specifies two replacement water-tube boilers operating at 20 bar, with steam outputs of 14 and four tonnes per hour. Current charter particulars give an eight-knot cruising speed and approximately 3,000 nautical miles of range; SuperYacht Times records a maximum speed of 12 knots. These are published specifications rather than a recent independent sea trial.
Her history includes a fire and sinking in New York in 1926, followed by salvage and reconstruction. Acquired by the US Navy in 1942, she served as USS Dauntless and became Admiral Ernest King’s flagship before returning to civilian ownership. A comprehensive restoration undertaken between 1997 and 2003 recovered her period appearance while renewing essential systems. There are no model variants: her evolution consists of successive repairs, conversions and refits of the same vessel.
Present charter information reports another 18-month refurbishment completed in July 2026, covering engines, major equipment, paint, varnish, carpets and finishes. It advertises 13 cabins for a charter party of 12, whereas older particulars describe accommodation for 26 guests. Those historical and current capacities should not be treated as interchangeable. Current facilities include a pool, jacuzzi, sauna, hammam, massage room, hairdressing salon and gym, alongside classic wooden tenders and watersports equipment.
SS Delphine operates as a fully crewed yacht, with current charter sources quoting complements of 24 to 26. Her steam machinery is supported by dedicated engineering personnel. Advertised cruising grounds centre on the Mediterranean, including the French Riviera, Corsica, Sardinia and Italy. Her combination of extensive entertaining spaces, heritage machinery and modern wellness facilities supports both leisurely cruising and hosted gatherings.
Frequent questions
The reported original construction cost was over USD 2 million in 1921; the price field records that approximate historical build cost, not a series-production base price. No current public sale listing was verified: SuperYacht Times marks her as not for sale, and the former brokerage listing is explicitly archived, so no current asking-price range can be established.
Current charter particulars quote eight knots cruising and approximately 3,000 nautical miles of range, while SuperYacht Times lists a 12-knot maximum. Her propulsion consists of two original quadruple-expansion steam engines rated at 1,500 horsepower each.
Current charter advertising specifies 13 cabins and a maximum charter party of 12 guests. Older documentation describes accommodation for 26 guests, so historical sleeping capacity should not be confused with the current advertised charter limit.
Current charter sources quote 24 to 26 crew members, including dedicated personnel supporting the steam machinery. These are advertised operating complements, not a verified statutory minimum-manning requirement.
Great Lakes Engineering Works built her at River Rouge, Michigan, in the United States, launching her in 1921. Design credits include Gielow & Orr for the exterior and naval architecture, Antoine Wille for naval architecture, and Tiffany’s for the interior.
Current charter particulars publish consumption of 500 litres per hour. They do not specify the associated speed or machinery load, so this figure should not be treated as a complete operating-cost estimate.
