The World, operated by ResidenSea, is a ship that is also a residential community. The residents, from about 40 different countries, live onboard as the ship slowly circumnavigates the globe, staying in most ports from 2 to 5 days. The World has facilities similar to those onboard a regular cruise ship, and also some that are unique due to its residential nature. They include a small grocery store and delicatessen, a boutique, athletic facilities that include a golf simulator, putting green, casino, full-sized tennis court, jogging track and gym.
