The luxurious world of deepsea diving begins with the TRITON SPII

Triton 660/2’s sleek exterior

The TRITON 660/2 SPII is our second generation, entry-level superyacht submersible. It packs the power output of our Professional flagship TRITON 3300/3 MKII into a svelte new design and boasts all the key features expected of a Triton Superyacht sub.

It is an excellent choice for anybody wishing to pilot their own submersible and explore the wonders of the ocean with a family member or friend.

As our smallest, lightest Superyacht submersible, it is also the easiest to integrate with standard tender garages, cranes & davits, making it ideal both for new-builds and existing vessels. The TRITON 660/2 SPII model lineage has over a decade’s proven track record of continuous operation and enviable achievements.

The TRITON 660/2 SPII may be our least expensive Superyacht sub, but its features rival even our flagship Professional model.

Azores to Antartica

The TRITON 660/2 SPII is your ticket to the finest type of adventure


With the ability to dive to 660 ft / 200 m – five times deeper than Scuba – and virtually anywhere on the planet, your only worry will be where to dive next.

Coral reefs provide some of the most visually enthralling dives. In warm, clear waters, coral reefs display a stunning diversity of life. With a TRITON 660/2 SPII you’ll have the opportunity to witness first-hand the incredible spectrum of colour, photo-luminescent creatures of all types, rare invertebrates, the humorous activities of tropical water fish, and the daily lives of large pelagic animals.

The icy waters of Antarctica offer a vast array of marine life to observe from the warmth of your new submersible. Enjoy diving alongside penguins as they leap from icebergs, chasing their supper. Or observe meters-long jellies as they pulse majestically through the cool blue seas.

Triton submersibles have explored more locations than those of any other manufacturer.

The Clearest View

The best views are from a Triton.

All Triton submersibles feature our exclusive, German-made acrylic hulls. Unlike yellow-tinged budget options, Triton hulls are completely colorless, crystal clear, distortion-free and feature the same refractive index as water – meaning they seemingly disappear from view when wet. You’ll believe you could reach out and touch the fabulous subsea world around you.

Once you experience it for yourself, you’ll understand why Triton acrylic is the number one choice for productions like Blue Planet II and David Attenborough’s Great Barrier Reef.

The Finest Interior

Tritons are more comfortable. Our obsession with ergonomics and efficient packaging means that, even in our most compact models, there is more room for guests to relax and spend many hours enjoying the ocean. Your knees won’t be pressed against the glass in a Triton.

The interior of the TRITON SPII features one of our most luxuriously trimmed cabins. Fine leathers, including vegan options, combine with quality hand-craftsmanship to create an interior that is beautiful, sumptuously comfortable and durable. A Triton interior is built to last.

A Superior Ownership Experience

Every Triton ever delivered has been to specification and budget. Importantly, each remains in active service and Certified to their original dive depths. And every single one of them benefits from a truly world-class after-sales service that is without peer.

Triton has such confidence that our clients would recommend us, that we will gladly provide prospective clients with the contact details for the Owners Representative for every submersible to earn the Triton badge.
