Owned by Richard D. Fain, the $1.4-billion, world’s largest ship, “Oasis of the Seas” is finally finished. It’s five times larger than the Titanic, has seven neighborhoods, an ice rink, a golf course and a 750-seat outdoor amphitheater. The Oasis, known as NB-1363, is so tall she needs a retractable funnel, or smokestack, to duck under bridges such as the Verrazano-Narrows Bridge in New York or the Great Belt Bridge in Denmark. The ship that mingles the glitter of Las Vegas with the vivid fantasy of Disney is estimated to have the useful life of 30 to 40 years. Among the host of entertainment options that the ship has to offer, scuba-diving lessons, two rock-climbing walls, two surfing simulation wave makers, a basketball court and four pools are a few to name that aim at vanquishing the notion of cruising as a sedentary holiday. The world’s largest zipline also features an elegant piazza with shopping and restaurants, a spa hosts yoga and Pilates, even botox treatments and teeth whitening. The voyager that is bigger than any biggest of the past era is just wow and if we could say, that world might not see anything bigger than this.
