Royal Caribbean International has revealed its new cruise ship Oasis of the Seas will boast two surf simulators, a teen spa, beach pool and private cabanas.

The cruiseline has unveiled plans for two more ‘neighbourhoods’ on board the ship, which is the largest in the world and goes on general sale on September 3.

The announcement of a pool and sports zone, and a vitality at sea spa and fitness centre, follow news of a Central Park on board, Boardwalk, Royal Promenade, amphitheatre and carousel.

The pool and sports zone will stretch the length of the ship and features private cabanas, four types of pool and two FlowRider surf simulators, each one of which will be larger than the single FlowRider on the ship’s Freedom-class ships, such as Independence of the Seas.

It will have the first beach pool at sea with a sloped entry, with two whirlpools either side, as well as a main beach pool. There will be a two-deck high glass-panelled open air solarium; nine-hole miniature golf course; sports court for basketball and volleyball; and a zip-line cable ride.

The vitality at sea spa and fitness centre includes a dedicated kids and teen spa; saunas and steam rooms; and a new cafe offering smoothies, juices and healthy snacks.

The ship launches in December 2009. It spans 16 decks and carries 5,400 passengers.
