The Symphony of the Seas is vastly larger than the Titanic, illustrating over a century of maritime engineering progress. While the Titanic was the largest ship of its time in 1912 at 882 feet long and 46,328 gross tons, the Symphony of the Seas (an Oasis-class ship) is approximately 1,188 feet long and weighs a staggering 228,081 gross tons. This means the modern ship is nearly five times the internal volume of the Titanic. In terms of capacity, the Titanic could hold around 2,400 passengers and crew, whereas the Symphony of the Seas can accommodate up to 6,680 guests plus 2,200 crew members. Standing next to each other, the Symphony would appear twice as high as the Titanic, featuring 18 decks compared to the Titanic's nine. Today's "floating cities" offer amenities like zip lines, ice rinks, and water parks that were unimaginable on the Titanic, which focused on a more linear, traditional form of transatlantic luxury travel.
