She rowed her 19-foot boat named Liv on a 2,817 mile solo journey from Dakar, Senegal, on Africa’s west coast, to Guyana on the northeast coast of South America.
The journey began on January 3 and ended March 13.
She rowed to raise money and awareness for the Blue Planet Run Foundation, a nonprofit whose goal is to bring clean drinking water to the estimated 1 billion people worldwide who lack it.
Spotz rowed for as many as 10 hours a day with breaks for naps, navigation and boat maintenance. At night, she would drift aboard the specially designed ocean row boat, which had equipment including solar panels for power, a satellite phone and a laptop computer.
"I would cook three dehydrated meals a day on a little stove," she said as she devoured a melon at the dock in Georgetown. "At night I would update my Facebook and e-mails. There is not much else to do on a row boat."
