Dallas Cowboys owner Jerry Jones has taken his state’s unofficial slogan to heart: Go big or go home.

The billionaire businessman is the new owner of a custom superyacht roughly the length of a football field, at 357 feet, which Mr. Jones got to take out for a cruise in time for the holidays. Dutch yacht builder Oceanco delivered the fuel-efficient ship to its “proud owners” a few days before Christmas, the builder announced.

Mr. Jones, 76—whose net worth is valued at $6.8 billion—reportedly spent $250 million on the impressive yacht, $110 million more than he paid for the NFL team in 1989. Mansion Global could not independently confirm the final price.

Oceanco and naval engineering firm Lateral rolled out a new energy-efficient design concept for the superyacht, named “Bravo Eugenia” after Mr. Jones’s wife, Genie. The ship has a single-tiered engine room, which allows for the ship’s slender design and more room for guest accommodations, according to the builder.

The sleek white superyacht has two helipads and ample storage space for the owner’s large selection of water toys, according to the builder.

There’s also a suite of spa amenities, including its own massage room, sauna, steam room and plunge pool. The lower deck encompasses a gym and a luxurious “beach club,” a yachting term for the ship’s waterside lounge.

The contemporary interiors by British firm Reymond Langton feature maple wood and pearl lacquer finishes with contrasting ebony details.

“We worked very closely with the owner to find the perfect artisans and craftsmen in creating bespoke artworks, fabrics and signature furniture pieces that reflect the owner’s style and essence and combine to create a warm, inviting environment for all on board,” Pascale Reymond, partner in Reymond Langton Design, said in a statement.

Mr. Jones and reps for the Cowboys did not immediately return request for comment. But public records link the ship to Mr. Jones, who obtained a license for the ship’s radio equipment from the Federal Communications Commission last month.

Work isn’t quite finished on Mr. Jones’s new toy. He had to return the superyacht to the Netherlands after the New Year for some final touches, according to Oceanco.
