Silver Endeavour

Silver Endeavour, originally built as Crystal Endeavor by MV Werften in Germany, is the world's largest ice-class expedition yacht and was the first purpose-built Polar Class megayacht for the luxury cruise market. The ship featured first-of-its-kind additions including a submarine and remote-operated vehicle with underwater camera capabilities. After Crystal Cruises collapsed, the vessel was acquired by Silversea Cruises and continued operating on Arctic and Antarctic expeditions.
