MSC Cruises new flagship MSC Divina has been floated out of dry dock in preparation for being fitted out in time to enter service next May.

The 140,000 ton, 4,363 passenger ship is the third in the Italian line’s series of Fantasia class vessels and is due to be christened in May 2012.

The 12th ship in the MSC Cruises’ fleet will feature an aft infinity pool. Called the Garden Pool, it will be designed and decorated as a deluxe area for quiet retreat, according to the company.

Work has also started on 400 of the 1,751 cabins – 100 more than sister ships MSc Fantasi and MSC Splendida.

The ship will feature a new reverse osmosis system for fresh water production that is claimed to require 40% less power and causes less impact on the environment.

Work started on the ship more than a year ago at the STX Europe ship yard in Saint-Nazaire, France and half of the fitting out has been carried out, including completion of the electrical networking, plumbing and public areas.
