Lee Wachtstetter, known as "Mama Lee" aboard the Crystal Serenity ship, became a permanent resident of the seas after her husband died.
"The day before my husband died of cancer in 1997, he told me, 'Don't stop cruising.' So here I am today living a stress-free, fairy-tale life," the former registered nurse told The Asbury Park Press.
Wachtstetter is one of small group of people who actually are permanent residents on cruise ships. The world's largest private residential ship is called The World, which has 165 homes and launched in 2002.
"My husband introduced me to cruising," Wachtstetter told The Asbury Park Press. "Mason was a banker and real estate appraiser and taught me to love cruising. During our 50-year marriage we did 89 cruises. I've done nearly a hundred more and 15 world cruises."
Wachtstter said she stopped counting how many countries she has visited.
"I stopped counting after 100," she said. "Just say I've been to almost any country that has a port."
The thing she misses the most from living on the land is her family, but she stays in touch with her three sons and seven grandchildren with her laptop.
"I hear from one of them everyday, and visit with them whenever we dock in Miami. Last year we docked in Miami five times," she said.
The $164,000 a year or so it costs her covers a single-occupancy seventh deck stateroom, meals, gratuities and entertainment.
This isn't the first time she's lived on a ship.
"Before coming aboard this ship I lived on a Holland America liner for three years," she said. "The day they announced they were stopping the dance host program was the day I decided to leave.
Three other women live on Crystal Cruise ships but none as long as Wachtstetter, according to Serenity's hotel director Hubert Buelacher.
"She's just an amazing woman, one of a kind," he told The Asbury Park Press.
