Personal submarines provide an exclusive ocean escape

When it comes to luxury, it’s pretty hard to compete with the ultimate ocean home: a superyacht equipped with a diverse fleet of vessels including the requisite toys and tenders for exploring rivers, estuaries, and islands. However, a more exciting and exclusive adventure awaits below the ocean’s surface. 

Triton Submarines LLC tapped into this idea long ago—that 97 percent of the ocean floor still remains unexplored—and today specializes in the production of a wide range of submersibles that can accommodate as many as seven passengers and dive to depths almost seven miles below the surface. 

A number of physical features, including the incredible clarity of Triton’s spherical pressure hulls made of a proprietary acrylic material that, according to Triton President Patrick Lahey, provide passengers with an “immersive experience,” distinguish Triton subs from others on the market. Attributes such as ease of use and durability make them a popular choice for yacht owners as well, highlights Lahey.

Take the Triton 1650/3 ($3.3 million), for example. This submersible can transport as many as three passengers to a depth of 1,650 feet. And because it weighs a relatively light 8,800 pounds and measures less than six feet tall, the sub can be launched easily from most luxury yachts. 

The Triton 3300/3 ($3.6 million), in comparison, remains the brand’s bestselling vessel. It weighs twice as much and is 2.6 feet taller than the 1650/3, but its ability to transport as many as three passengers more than half a mile below the ocean’s surface for up to 12 hours makes it ideal for both sightseeing and scientific expeditions. In fact, the Triton 3300/3 was extensively used by the BBC during the filming of a three-part documentary series on the Great Barrier Reef in 2016.

Still, the company’s most compelling sub, the Triton 36000/3, requires two years to build and has the potential to traverse previously unexplored areas of the Earth. The aquatic marvel, which features a lightweight and highly pressurized hull, costs approximately $30 million and is capable of safely (and comfortably) transporting three passengers to the deepest point of the Mariana Trench. 

“That,” says Triton CEO Bruce Jones, “is the ultimate submersible.”
