UNTIL THIS EVENING, “the best address on Earth” will be in Dublin.

The World, the largest privately-owned residential yacht on earth, is paying a visit.

The owners are keen to stress that this is not a cruise ship, but is to a community consisting of dozens of families.

The massive 664-foot vessel doesn’t quite stand up to some of the biggest cruise liners in the world, but isn’t to be scoffed at coming in at roughly the same size as Irish Ferries’ Ulysses.

Unlike a trip to Holyhead, however, a ticket for The World is going to be a lot harder to come by.

There are between 150 and 200 residents and guests on the ship at any time. They travel around the world to destinations ranging from the coast of France to South America.

“There are some residents who live on the ship year-round,” the owners say.

The majority continuing to be active in their professional lives and spending three to four months onboard.

RTÉ Ten reports that one of those residents is suspected to be Judge Judith Sheindlin of Judge Judy fame, who was spotted in Dublin at the weekend.

Each home on the ship is the property of the individual homeowner, and they come with a hefty price tag – The Daily Mail reports that a studio flat could set you back $1 million, along with annual membership fee.

You get a lot for that kind of money, including:

Six restaurants

Golf facilities

Full-size tennis court at sea

Swimming pools

Spa

Fitness center

Library

Cinema

The World is the 68th cruise visit this year to Dublin Port.
