By AI ChatGPT4-T.Chr.-Human Synthesis-23 January 2026
The Tanguingui wasn’t a modern luxury yacht, but rather a private motor yacht built in 1915 that the United States Navy used as a patrol vessel during World War I. Before and after its naval service it was a civilian yacht.

Key facts:
- Built in 1915 by the New York Yacht Launch and Engine Company in New York.
- Originally a private motor yacht used for pleasure cruising.
- Acquired by the U.S. Navy in 1917 and commissioned as USS Tanguingui (SP-126) for patrol work during World War I.
- After the war (in 1919) she was returned to her owner and resumed civilian use.
- About 19 m (63 ft) long with a small crew and outfitted for coastal patrol rather than luxury cruising.
Tanguingui isn’t a modern superyacht like those you might see today in charter fleets — it’s a historic early-20th-century motor yacht that briefly served as a naval patrol vessel.
