The Ice Class 1D cruise ships are strengthened to the Finnish-Swedish Ice Class 1D standard, providing basic ice capability for light ice conditions and summer polar operations. They feature reinforced hull plating in critical areas, protected propellers, and systems designed for operation in broken ice and cold climates. The ships include large observation lounges and Zodiac platforms for shore excursions in polar regions. This class offers a cost-effective solution for operators running seasonal Arctic and Antarctic itineraries.
