Explore the SunStone Infinity class - our ships built to withstand the roughest conditions of the polar cruising offering the highest comfort levels for the passengers.

The Story
The Infinity Class is a unique SunStone ship series offering modern Nordic interior design, state-of-the art hull and technical features, world leading fuel efficiency and environmental responsibility, as well as maximum passenger comfort - all at an unmatched price point.

A result of an international collaboration

Since 2019, the fleet has been expanding with a new series of state-of-the art expedition vessels in a world’s first partnership between Danish expedition cruise experts (Niels-Erik Lund/SunStone), Norwegian naval architects (Ulstein), American interior designers (Tomas Tillberg Design USA), Finnish interior contractors (Mäkinen), and a Chinese Shipyard (CMHI).

A multiple award winner

Since the first delivery, the Infinity Class has been awarded for its eco-friendly design and construction.  Multiple Infinity Class vessels have received notable mentions from media outlets like Cruise Critic Australia, and Magellan awards from Travel Weekly Magazine.
