Finnish-born Harri Kulovaara is designing what will be the largest cruise ship in the world when it is completed later this year. Royal Carribean's Oasis of the Seas will carry 6,300 passengers, 2,000 more than any other ship. The ship is unusual in that it is divided in to two halves, each with a six story tower of cabins with enough space between the two towers to fit a football-field sized park. And there are many other features that make this ship more of a city than a boat.
