The ULSTEIN CX103 design

The vessel is based on the ULSTEIN CX103 design. It has an ICE CLASS 1A certification for polar cruising. It adheres to the highest standards of comfort and safety, including the SOLAS (Safety of Life at Sea) certification with a Safe Return to Port passport.

The new PC6-class expedition cruise ship, which has not yet been named, is scheduled to enter service in 2025. It is designed to offer travellers an immersive and comfortable experience, featuring up to 95 passenger cabins. The ship will have various amenities, including restaurants, a lecture space, lounges, a 180-degree indoor observation deck, outdoor viewing areas, a gym, a sauna, a spa, and a specially designed platform for kayakers and divers. Additionally, the vessel will include a sea-level Zodiac loading platform and a mudroom to enhance off-board activities.

While all SunStone's Infinity-class vessels share the same basic design – 104.4 metres in length and 18.4 metres in width – each is customised according to client specifications, including passenger and crew capacity and the design of public spaces. A distinctive feature of this vessel, shared with three other vessels in the series, is the inclusion of windows around the bow lounge, offering a bright, nature-integrated indoor environment.
