A new residential cruise ship plans to sail around the world every 2½ years. Cabins start at $11 million.

The ship’s 132 cabins would accommodate up to 300 residents and guests. However, Alain Gruber, the CEO of Ulyssia Residences, told Business Insider in an email that he estimates the vessel will have an average of 200 guests onboard.

It’s a relatively steep starting cost — one of Villa Vie’s most expensive cabins was reserved at $469,000, although it’s about three times smaller than Ulyssia’s smallest 1,216-square-foot accommodation.

Yet both are compact compared to Ulyssia’s penthouses, the largest of which would span 10,570 square feet. As expected, with this size comes a steeper starting cost of €60 million, about $67.04 million.

No matter the square footage, Ulyssia’s floating condos would all have amenities like reception rooms, kitchens, terraces, and floor-to-ceiling windows.

Gruber said residents would vote on management’s itinerary options, finalized three years in advance.

Like many mass-market around-the-world cruises, the ship would spend at least three nights — up to one week — at every port, giving travelers more time to immerse themselves in each destination.

Expect up to two “major expedition” segments every year, one in a cold climate (like the Northwest Passage or the Arctic) and one in warmer weather (like Madagascar or Micronesia).

The ship would have children and education services to accommodate the youngest travelers.

As for the older guests, the company’s CEO expects most to be “entrepreneurial” — the kind of people who would own multiple homes in different countries, Renato Chizzola, Ulyssia’s senior vice president of lifestyle and development, said in a press release.

Ulyssia doesn’t have a ship yet, and the vessel acquisition process has become an infamously difficult challenge for similar startups.

Residential cruise companies can either build a new ship (as Ulyssia plans to) or refurbish an older used vessel.

Storylines is pursuing the former by building its own luxury residential ship. However, its launch has been delayed eight years to 2027, and former employees, consultants, and investors told BI in 2023 that they’d started to doubt the vessel would ever be built.

Life at Sea Cruises intended to purchase a used vessel for its three-year sailing. But it failed to secure enough funding and canceled its voyage two weeks before its planned departure in November 2023.

The company filed for bankruptcy eight months later.

Villa Vie successfully purchased a more-than-30-year-old vessel for its never-ending cruise, which could set sail in the coming days. However, its launch has already been delayed four months amid issues like the ship’s aging rudder stocks and certifications.

The popular German shipbuilder has constructed cruise ships for recognizable companies like Disney, Celebrity, Norwegian, and Royal Caribbean.

Ulyssia said construction on its vessel is scheduled to begin in the fall of 2024 “but no later than” September 2025. The ship would then be completed in October 2028 (but by March 2029).

Frank Binder, the company’s founder and chairman, is the principal investor. Customer deposits and financial institutions will also help finance the shipbuilding process.

Ulyssia is promising amenities like a spa and gym with indoor padel and pickleball courts.

Take a dip in the ocean water at the ship’s marina, which would be outfitted with water toys and dive equipment, including two submersibles.

Or, head to the skies with one of the two eight-seater helicopters.

Residents can also expect traditional cruise ship facilities like pools, a cigar lounge, a nightclub, a theater, and a medical center.

The latter would be upgraded with equipment for diagnostics and surgery, such as a magnetic resonance imaging (MRI) scanner.

The World and Ulyssia have two key differences — their vessels’ ages and their residents’ net worth.

The World’s ship would be 26 years old by the time of Ulyssia’s planned launch in 2028.

Ulyssia’s minimum is €25 million — about $27.87 million.

At least its travelers would get to see the world on a luxury superyacht. The helicopters and submarines probably help, too.
