The ship's interior design, crafted by Tomas Tillberg Design, prioritises bringing the outdoors inside. The two-story atrium and spectacular forward bow windows connect passengers to the natural world. It’s all about seamlessly transitioning from the ship’s cosy interiors to the awe-inspiring landscapes beyond. Public spaces include two restaurants, two bars, a heated outdoor swimming pool, pool bar and Jacuzzis, a gym, sauna, relaxation, and wellness areas. There is also a library lounge, a citizen science centre, and a lecture theatre. Observation decks offer panoramic views of wilderness and wildlife.
The Infinity-class expedition cruise vessel boasts a unique feature shared by three sister vessels: windows enveloping the bow lounge, flooding the interior with natural light and creating an immersive connection to the surrounding nature. Imagine sipping your morning coffee while gazing out at the breathtaking vistas through these expansive windows! Built to Polar Class 6 standards, the Douglas Mawson accommodates guests in 80 cabins.
Designed by Ulstein Design & Solutions AS, this vessel is part of the Infinity class, which introduced the patented X-BOW design to the cruise industry. This innovative design significantly reduces wave resistance and vessel motion, enabling smoother and more efficient operations in challenging sea conditions. It also reduces noise and improves fuel efficiency, making it an excellent choice for expedition cruising.
