POSTSCRIPT P.4
In November 2007, MS Explorer, a small expedition cruise ship operated by GAP Adventures sank in the Bransfield Strait, close to King George near the South Shetland Islands.
It seems the master mistook thick, multi-year Antarctic ice for thinner Baltic pack. A later investigation found he also maintained speed while navigating at night. On board were 154 passengers and crew members, all of whom were safely evacuated to lifeboats before the ship sank.
