The Delphine, built for Horace Dodge in 1920 by the Great Lakes Engineering Co. and named for his daughter, measures 258 feet long and contains accommodations for 20 guests and a crew of 55, the Detroit Free Press reported Monday,
The vessel caught fire and sank during a trip to New York in the 1920s and was raised and restored. It was sold to the U.S. Navy during World War II and returned to the Dodge family after the war.
The Belgian family purchased the Delphine in 1997 and operated it as a charter vessel out of Monaco for a price of $1.5 million per month.
The boat is currently docked in Tunisia and is listed for sale with an asking price of about $50 million.
