Liz Clark is traveling around the world on a sailboat along with her feline first mate.
Clark and Amelia the Tropicat live on a boat named Swell, which is 11 feet wide and 40 feet long.
Clark told BuzzFeed News that she found Amelia when she was only 6 months old and adopted her.
"She has adapted to living surrounded by water," Clark said of her cat companion. "She's learned to trust that she will be safe with me."
Clark, who is originally from San Diego, said she "had dreamed of sailing around the world since I was a kid."
Clark worked on Swell for two years before it was seaworthy, and she finally set sail in 2005 from California.
Clark has now traveled along the western coast of Mexico and Central America, as well as to the South Pacific.
She has so far logged more than 18,000 nautical miles.
