Portland, Maine (AP) - A luxury cruise ship that serves as a floating vacation home as it navigates around the world has scheduled a stop in Maine.

Portland spokeswoman Nicole Clegg says The World, a 644-foot ship with 165 residences ranging from studio apartments to a six-bedroom ocean penthouse, will visit Portland from Oct. 15-17, 2012.

Residents live aboard the ship.

For its 2010 voyage, the ship left Australia in January on a route that has included Southeast Asia, India, the Suez Canal, the Mediterranean Sea and Europe. It will then go to Greenland and along the east coasts of North and South America before ending its yearlong trip with a visit to Antarctica.
