A series of expedition cruise vessels are being constructed at the CMHI Haimen base for SunStone Ships. These vessels in the INFINITY series are all based on the ULSTEIN CX103 design.
The vessels are chartered to travel operators for high-end luxury cruises. The hull is ice-strengthened (Polar Class 6), and the vessel features the ULSTEIN X-BOW for smooth sailing in rough seas. This patented hull, originally developed for offshore work horses, was firstly introduced to the cruise industry in 2019, when the 'Greg Mortimer' was delivered. The hull shape reduces fuel consumption when cutting through the waves and therefore also reduces local emissions.
