Royal Caribbean International marked two important milestones in the development of its Quantum-class ships at the Meyer Werft shipyard in Papenburg, Germany, this month.

Quantum of the Seas received its first block, as the keel was officially lowered and put into place, and Anthem of the Seas, Quantum’s sister-ship, had its first piece of steel cut, signaling the first step in the ship’s construction.

“Today is a very special day in the development of our new Quantum class, as we are now two steps closer to delighting guests around the world with Quantum cruising,” said Adam Goldstein, president and CEO. “It’s incredibly rewarding to see Quantum of the Seas and Anthem of the Seas coming together so well, and today we not only honor these two very important milestones, but also recognize the years of hard work and dedication from the team developing these ships.”

The keel laying marks the beginning of the ship’s physical construction. During the ceremony, a 430-ton block measuring 59 by 75 feet was lifted into the building dock with an 800-ton crane. Newly minted coins placed under the keel stay in place until the end of construction, when they are presented to the ship’s captain and crew to be placed onboard the ship. According to maritime tradition, the coins are said to bring luck to the ship.

Quantum-class ships will span 16 deck and carry 4,180 guests. The ships will debut new features, including as RipCord by iFLY, the first skydiving experience at sea; the North Star, which transports guests more than 300 feet above the ocean; and The Sea-Plex, the largest indoor sports and entertainment complex at sea with bumper cars and a roller skating ring; and more.

The Quantum class will debut in autumn 2014 with Quantum of the Seas, followed by sister-ship Anthem of the Seas in spring 2015.
