The TRITON 660/7 and 660/9 AVA are the world's first submersibles with a free-form acrylic pressure hull. The patent-pending AVA pressure hull allows for maximum passenger comfort and an unparalleled viewing experience, with an interior volume three times that of the spheres on similarly sized multi-hulled submersibles. The expansive and flexible space enables you create experiences otherwise unimaginable in a submersible; whether it be casinos, private dining, or a wedding ceremony. The revolutionary design offers complete 360° unobstructed visibility for the finest passenger experience.
