At $275 million, this is the world’s most luxurious submarine. It comes with a lavish suite, a grand piano, a gourmet kitchen, and an observation lounge. Shaped like a fish, it can cross oceans with its range of 6,904 miles and even stay on the seabed for an entire week.

California-based designer Steve Kozloff is no stranger to fantasy and fantastic vessels. His concepts and ideas are outlandish and outstanding in equal measures, and while most haven’t made it out of paper yet, the stretch of the human mind and possibilities make his work incredibly exciting. The latest concept is dubbed the Deep Sea Dreamer, a 107-foot, fish-shaped luxurious submarine conceptualized for a couple that descends up to depths of 328 feet. The two-decker accommodates six people in two decks, with unparalleled views and experiences of the ocean below.


Thanks to the presence of large observational areas at the bow and the deck on resurfacing, coupled with comfy recliner chairs, the purpose of exploring the underwater world becomes fulfilled. Like a standard luxury yacht, this one features a master suite, complete with an en-suite bathroom and ample walk-in closet space.

With the Deep Sea Dreamer capable of staying 328 feet underwater for up to seven days at a time, there may be little opportunity for so many outfit changes and making the most of the space.

The most useful space aboard is the observation pod specced with designer furniture and a small bar, and a grand piano for live entertaining. The 107-footer offers a great feature of flexible docking for both conventional surface anchoring and submerged mooring choices, per Goaliathseries. When moored, the ship boasts a 2,440-square-foot observation deck. The commodious submarine offers no less than 1,500 square feet of living space and would set a billionaire back by at least $275 million.

Deep Sea Dreamer offers its owners many ways of enjoying the vessel and the surroundings both on and inside water. From acting like a pleasure craft to zipping like a sub and even staying stationary in the depths of the ocean, there is nothing this sub cannot do. It uses electric power only for 100 miles (161 km) and can spend a week stationary on the ocean floor.

The submersible paradise is outfitted with a gourmet kitchen to make the most of the serene setting and company. “Forget typical yachts,” the designer stated. “Deep Sea Dreamer is a submersible paradise designed for couples seeking ultimate privacy and an intimate connection with the ocean.”

Have you met the Migaloo M5 super submarine?

As the world’s first super submarine, the gigantic sub that’s 543 feet long sleeps 20 passengers and 40 crew members. The $2 billion underwater superyacht, in comparison to Kozloff’s Deep Sea Dreamer, manages to stay submerged 820 feet underwater for four weeks. Also, with $2 billion spent, the guests enjoy more than just the sweet tunes of the piano. The vessel packs an arsenal of jet skis, kite surfing, paddleboarding, six-person mini-submarines, and a helicopter. The Migaloo M5 yacht remains a concept, with no set date for its market debut.
