Indeed! Given that the ice in Antarctica is up to 5 kilometres thick with an average thickness around 2 km and mostly sitting on rock, a boat that could "sail through Antarctica" would be quite something!

She isn't even going to get near Antarctica except in benevolent (i.e. unusual!) conditions. She'd get down to the South Shetland Islands in summer, down to Anvers Island most years, and down to Rothera some years. These are all locations on the Antarctic Peninsula. She stands little chance of getting to Ross Island or to any of the bases in East Antarctica.
