After nearly two years of following the construction of the Oasis, we were lucky enough to experience the first revenue cruise on this new vessel. As the largest ship in the world, Oasis is 40% larger than the next largest ship, RCCL's own Freedom Class Ships. Vitals: 225,000+ GRT, 1181 Feet in length, 198 foot extreme beam, draught: 31 feet. On December 1st we arrived at the ship for our 4 day Labadee Extravaganza.
