An Australian sailor made history on Tuesday by becoming the first woman to sail solo around Antarctica.

Lisa Blair, 32, arrived back in Albany, a port town in southwestern Australia from which she set sail in January, early in the evening after 104 days at sea.

"There have been times where it's really rough conditions or freezing cold conditions where I've questioned my sanity, but there's been a lot of amazing times when I've been watching's an incredible experience to be surfing waves in the Southern Ocean," Blair told reporters waiting for her onshore.

The seasoned sailor undertook the journey in order to increase awareness of climate change, naming her boat Climate Action Now.

Blair had originally planned to break Russian adventurer Fedor Konyukhov's 2008 record for the fastest solo, nonstop and unassisted circumnavigation of Antarctica.

But the mast of her boat broke halfway through her journey, forcing the sailor to spend eight weeks in Cape Town, South Africa, while the vessel underwent repairs.

Blair is the third person to ever compete in the Antarctica Cup Racetrack, a 360-degree sailing course through the Southern Ocean, also known as the Antarctic Ocean.
