The new Ultramarine 200-passenger polar ship is purpose-built for safety and far-off exploration. The vessel boasts specialized exploration tools, cutting-edge safety measures and an incredible 70-day cruising range to focus on hard-to-reach places, while at the same time providing a high-end onboard experience. Ultramarine was built in 2021 by Croatia’s award-winning Brodosplit, the largest shipyard in the country, and is designed by LMG Marin, Europe’s leading naval architect. Her first sailings were in the Arctic in early 2022.

Exploration is prioritized with Ultramarine’s twin helicopter and helipads for heli-skiing, flightseeing and expeditions to otherwise inaccessible places as well as an innovative, internal hangar and launching system for Zodiacs. These exploration tools, the ship’s specialized, cutting-edge safety features, and the provisioning and waste handling systems (enabling a 70-day operational range) all ensure the ability to go farther into the polar regions, more safely and more easily than before. For these, and many other reasons, the Ultramarine is among our top choices for passengers seeking Antarctica luxury cruises.

Designed in collaboration with active expedition leaders, this ship offers innovative features to increase guests’ on- and off-ship experiences. Choose the Ultramarine for an excellent balance of personal, operational and public spaces.

Safety & Sustainability Aboard Ultramarine

The groundbreaking safety features of Ultramarine include 13 fully redundant critical systems, twin propellers powered by four diesel-electric engines in two separate engine rooms for consistent backup and engine reliability, stabilizers, as well as a fully operational emergency bridge. This expedition vessel also has an ice strengthened hull and dynamic positioning capabilities. Her sophisticated and environmentally friendly waste handling systems allow for treatment of waste to be managed safely in far-off distances. Her numerous innovations are designed to minimize her environmental footprint to an extent previously unseen for a vessel of comparable size, including a sophisticated water treatment system, state-of-the-art waste handling, a leading-edge heat recovery system that recycles excess energy back into the ship, LED lighting, and the use of entirely recyclable materials to construct it. The dynamic positioning technology also means no need to anchor, avoiding damage to sensitive seabed ecosystems. Finally, digital wristbands enable both keyless cabin entry and computer-logged tracking of entry and exit from the ship.
