How Much Does the Largest Cruise Ship Weigh?

By Michael Ferguson

The largest cruise ship in the world is a behemoth. It weighs an eye-watering 227,000 tonnes and is the length of almost four football fields.

The ship, named Symphony of the Seas, is owned by Royal Caribbean International and was launched in April 2018. It has a capacity of 6,680 passengers and 2,200 crew members, making it one of the largest floating cities in the world.

The Symphony of the Seas is part of Royal Caribbean’s Oasis-class series of ships. This class includes five other ships with similar features, including Allure of the Seas, Harmony of the Seas and Oasis of the Seas. All six ships are over 362 metres long and 66 metres wide, making them among some of the biggest vessels ever built.

The Symphony of the Seas has 18 decks filled with features such as restaurants, bars, theatres, cinemas and swimming pools. There are also plenty of activities on board for passengers to enjoy during their stay on board such as ice skating rinks, rock climbing walls and even zip lines!

The sheer size and weight of these vessels means that they require a lot of power to move them through the water. Symphony of the Seas has four engines with a combined power output equivalent to 50 Formula 1 cars! This allows it to reach speeds up to 22 knots (41 km/h).
