Sailor stays cool in record attempt

Lisa Blair set off from the Western Australian town of Albany on Monday as she attempts to be the first woman to circumnavigate Antarctica solo, non-stop and unassisted in less than 100 days.

The 32-year-old sailor from Queensland will have to navigate through the Southern Ocean's Cape Leeuwin, Cape Horn and Cape Agulhas, which are regarded as some of the world's most dangerous stretches of water.

The risk of huge seas, strong winds and icebergs are only some of the challenges Blair will have to contend with.
