Triton achieved a new milestone with the delivery of the first ever 6-person acrylic-hulled submersible certified to 3,281ft/ 1,000m, featuring the world’s largest transparent, spherical passenger compartment, providing a 360⁰ window to the ocean outside.


Triton Submarines LLC, a leading manufacturer of personal submarines designed for yacht, hospitality and cruise ship deployment, has announced the delivery of the first unit in their TRITON 3300/6 model series. As the world’s largest capacity acrylic-hulled personal submersible with a certified depth rating to 1,000m (3,300ft), the delivery incorporates numerous significant milestone ‘firsts’, further lengthening Triton’s existing list of pioneering achievements.

Within the voluminous interior of the largest acrylic pressure hull ever produced, up to five guests will join their pilot for memorable adventures from the luxurious comfort of what has been described as ‘a salon under the sea’. Fabricated utilizing advanced acrylic polymerization, the vast acrylic sphere is over 100in (2.5m) in exterior diameter and boasts over 175 ft3 ( 5m3 )of interior volume, commensurate with the cabin of a six-passenger private jet (Cessna Citation CJ2+ 5.5m3). Equipped with club-class seating, the custom leather interior compliments the striking ‘Tiffany Blue’ exterior livery selected by the Owner.


The scale of the panoramic passenger compartment provides a social space from which guests can enjoy a shared dive experience. This unique feature of the TRITON 3300/6 simply cannot be rivalled in multi-hull vessels or smaller craft. The TRITON 3300/6 is the twelfth submersible delivered by Triton that has been certified for operational depth of 3, 281ft (1,000m) depth or beyond, resulting in Triton’s clients comprising the vast majority of an elite and exclusive group of deep ocean explorers.


The Triton team worked closely alongside the Owner’s representative for the project, SEMarine, who were instrumental in the successful integration of the submersible and support systems onboard the 466ft (142m) Lürssen host vessel. Triton’s Principal Designer John Ramsay describes working with SEMarine in the development of the TRITON 3300/6: “Following the development and groundbreaking success of the TRITON 36000/2 (LF) – which, notably, achieved the world record for the deepest ever submersible dive – it was a welcome return to designing another milestone submersible. This time, the focus was very much more on luxury and the guest experience rather than extreme depth. I’m particularly proud of the level of comfort and space we have achieved in a submersible that is less than 50% heavier than our three-person equivalent. In addition, the six-passenger submersible is actually 20cm (7.8in) lower in height than the three-passenger model and features a new lifting system for the widely adopted overhead gantry cranes, a critical factor in integrating this unit with a wide range of mega-yacht garages.”


Simon England of SEMarine, Technical Consultant to the Owner through the build of the yacht says:

“We looked closely at all producers capable of building a 1000m submersible to meet our client’s requirement. Triton was chosen for their submersible experience, outstanding design and relentless attention to build quality. We are proud to have been involved with the development of the TRITON 3300/6 for our client’s yacht. The dive I took with Triton during the integration planning phase was the highlight of my year.”

The model is one of several that addresses the increasing demand Triton Submarines is experiencing from both mega-yacht owners and the hospitality sector for larger capacity submersibles that allow families or groups of guests to partake in experiences that generate unique shared memories.


“We are extremely grateful to the Owner for providing us the opportunity to build this first

TRITON 3300/6,” comments Triton’s President Patrick Lahey, “and share his pride in the astonishing final results achieved by the team here at Triton. While we delivered a 24-passenger submersible earlier this year to be employed in the commercial tourism sector, the delivery of the TRITON 3300/6 represents the first of several six-, seven- and nine-person Triton models you’ll see delivered in the near future. Among the next deliveries is in fact a 500m version of the 3300/6 that is currently under construction – the TRITON 1650/7 Configurable – which features even more interior volume and can accommodate up to seven persons.”


Having pioneered access to the deep ocean for their rapidly growing group of owners, Triton Submarines is currently working on the next evolutionary stages of humankind’s exploration of the marine environment: redefining how we experience and interact with the ocean. As interior volumes increase, so does the opportunity to configure the passenger environment to reflect the lifestyle choices of the owner.
