This week, sailor Kirsten Neuschafer, in the lead in the grueling nonstop, solo round-the-world Golden Globe race, rounded Cape Horn, a significant milestone in this difficult competition.

She’s the only woman in the race and only the second woman ever to compete in the intentionally low-tech Golden Globe.

We take a look at Kristen’s accompishments, and also celebrate a few of the other women in history who have accomplished sailing around the world alone.
