Part of "Life on the Edge" series. Out at sea, Johanna's running the show. Namibia's first female trawler captain has a crew of 23. But it's not so long since she was living in a shantytown, with no running water, a girl from the villages who used to walk 14 kilometers to school. On her few days' leave on land, Johanna travels 1,500 kilometers back home to find other girls seizing the chance like her.
