The two below are the same drawing that I worked on a year ago, and if they were real they'd be the second largest cruise ship in the world. However though I have recently redesigned it so that it looks a bit more realistic(below). The numbers and such you see on the right hand corner are the length: 1,152 ft and the height 237 ft, add onto what the passenger capacity might be along with the number of crew.
While I was working on this after an extensive search through all previous drawn lifeboats I realized that none were big enough for a ship of this size(as it is slightly small than the Oasis of the Seas), and I did work in with current ones already available on shipbucket and they simply looked ridiculous. Thus I went and drew up the current largest in use lifeboat the CRW55 mega, whose max capacity is 370.(
