Scenic has announced that Scenic Eclipse will offer guests an immersive underwater experience on board Scenic Neptune – a U Boat Worx Cruise Submarine 7.

The ship, labelled the world’s first discovery yacht, is scheduled to launch in January 2019.

The custom-built six-seater submarine, which can dive to a depth of 300m, will provide “unparalleled access to some of nature’s most beautiful marine environments”, according to Scenic founder and chairman, Glen Moroney.

“From inside Scenic Neptune, each guest will enjoy an uninterrupted view thanks to the strategic placement of all components and the use of an ultra-clear acrylic hull, expertly engineered to make you feel at one with the ocean,” he added.

“The sub is able to do from eight up to 12 dives per day, depending on the length of dive, giving as many guests as possible access to this unique opportunity.

“Because the cabin is pressurised, there is also no need for a slow ascent or descent. One of the thrills for guests is a fast, upward journey where they pop out from below the ocean with a splash.”

Scenic Neptune consists of a three-person pod on the front and at the back of the sub for a total of six guests, plus the pilot. Seats are mounted on a platform that can swivel 180 degrees to allow viewing from both sides.

The Scenic Eclipse fleet has been designed with a rating of Ice Class 1A Super (Polar Class 6), the highest of any luxury vessel, coupled with technology to enable it to operate in extreme environments, such as the Arctic and Antarctic coasts.

“Access to small ports and to the sensitive Polar Regions are elements of the programme development for Scenic Eclipse,” said Moroney.

“As such, the technology we have put into the design and construction of our fleet is paramount.”
