Scenic has released the first interior images of its custom-designed Scenic Neptune submarine.

The submarine – which will operate on the upcoming expedition yacht, Scenic Eclipse – will offer up to eight dives a day and reach depths of 300m.

It will seat up to six guests plus the pilot, while seats will swivel 280 degrees for underwater views from both sides of the submarine.

Scenic Neptune pilot Remy Izendooren said: “Guests will embark on an awe-inspiring adventure to the underwater world.  Volcanic pinnacles, sheer walls, majestic wrecks, a wide diversity of marine life and beautiful reefs lie waiting to be discovered.

“The world has many spectacular dive sites waiting for us to explore, from sunken wrecks and vibrant tropical reefs to a sea floor teeming with life in Antarctica.”

Scenic added that Neptune will feature “internal climate control and a surround sound music system”, as well as acrylic spheres constructed from a material with the same refraction index as seawater, meaning it “visually disappears underwater and provides a very open and spacious feeling”.

Scenic Eclipse is scheduled to launch on 15 August 2019 with an Iceland & Atlantic Canada sailing.
