Although I personally do not see the draw, the popularity of ocean cruises just keeps going up. To keep up with the demand, cruise ships are getting bigger all the time. Royal Caribbean's new ship Icon of the Seas is twenty stories tall and can carry almost ten thousand people, but it also cost two billion dollars and took years to build. Cruise companies get more bang for their buck by "jumboizing" their existing cruise ships. The "jumboization" process takes about nine months from start to finish, removes a ship from service for only a couple of months, and costs around $80 million.
What they do is cut a ship in half, slide in a new section in the middle, and weld it all back together. This requires precise measurement and design, so that the new section can be built to match every hallway and pipeline that runs through it. The exciting part (if seen in time-lapse form) is when the ship is brought in and cut into two pieces with acetylene torches. The parts are separated, and the new section is rolled in and welded. When it's done, a much longer ship leaves the dock, ready to book hundreds more passengers than before. New Atlas explains jumboization and has a series of videos documenting how this has been done to several different ships. So the next time you want to spend a week or so floating on the waves up close and personal with a few thousand strangers, there may be a ticket for you. -via Boing Boing
