Every year, cruise ships get bigger and bigger. If you’re like us, you like to sail the largest cruise ships possible. 2019 is the year of the massive vessels. If you’re starting to plan your 2019 cruise vacations, we hope that this helps to find the massive vessel you’re looking for.

Despite the post title indicating five ships, we’re actually listing out the Top Six Largest Cruise Ships in the world. Why? Well, because there’s a tie for biggest ship mixed in there among the ranks. Ships are built in “classes” and often times the cruise lines will re-use plans. When they find something that works well, they’ll stamp out (gross understatement) a few more of the same footprint.

Evidently, people liked the the big ships, because the average ship size keeps getting larger and larger. As you can see from the chart below, the average ship size in this latest decade is 134,000 gross tons. This is over 4x the size of the average cruise ship in the 80’s!

Average Ship Size by Decade

If this pace continues, the largest cruise ship in the world in 2050 will be the size of Delaware. But, back to today. Below you’ll find the largest cruise ships in the world by end of 2019.

Check out this quick video highlighting the world’s largest cruise ships.

5 Largest Cruise Ships in the World in 2019

Here’s the list below with some additional facts on each vessel.

#1 – Largest Cruise Ship in the World: Symphony of the Seas

Symphony of the Seas Info

In addition to being the biggest cruise ship ever built, the Symphony of the Seas is also Royal Caribbean’s newest vessel. The company describes Symphony of the Seas as follows: “Clocking in at 1,188 feet long and with 18 total decks—about the height of the Leaning Tower of Pisa—this ship dominates with the title of the largest in the world.”

The Symphony of the Seas took the title for largest ship from its sister (how rude, right) the Harmony of the Seas, built two years earlier. It clocks in at roughly 1,000 tons larger. While this is the equivalent of 500 normal automobiles, it represents about 0.05% of the ship’s total weight.

The ship is so huge, it has seven different “neighborhoods!” They include the following.

Boardwalk

Pool & Sports Zone

Central Park

Royal Promenade

Entertainment Place

Youth Zone

Vitality Sports and Fitness

While these neighborhoods aren’t new to Royal Caribbean, there are a few fresh additions to the Symphony. These include the new Playmakers sports bar, larger zipline, 1,000 SF “Ultimate Family Suite,” and Hooked Seafood Restaurant.

Symphony of the Seas Fun Facts

The Symphony of the Seas has more pieces of art on board than found in the Louvre Museum in Paris! On an average 7-night sailing, over 60,000 fresh eggs are used on board! On a week-long cruise, six million coffee beans are required to make the total coffee made on the ship! During a 24-hour period on the ship, roughly 500,000 gallons of fresh water are consumed. Compared to one eruption of Old Faithful, the Symphony’s 24 pools and water attractions use close to 100x that amount of water.

#2 – Largest Cruise Ship in the World: Harmony of the Seas

Harmony of the Seas Info

Like it’s sister ship, the Oasis-class vessel hosts four swimming pools and 10 hot tubs. You’ll find 20 dining venues and over 11k pieces of art! Guests love the “Perfect Storm” water slides and also the 10-story, dry slide called the Abyss. There’s an Ice Rink, Aqua Theater, and Broadway-style Theater. Sporting enthusiasts have the options of basketball, ping pong, rock climbing, or surfing on the Flowrider. Shopping fans can’t get enough in the ship’s promenade mall.

It’s the World’s 2nd largest cruise ship and Royal Caribbean makes great use of every inch!

The Aqua Theatre on the ship has a deeper swimming pool than any other located on a cruise ship. It can be adjusted to a depth of 18 feet. To facilitate its speedy internet, the Harmony has a dedicated satellite. On board, you’ll find 184 “mixologists” and bartenders to make sure you’re quenched… oh wait, 185 if you include the bionic bartender.

#3 – Largest Cruise Ship in the World: Allure & Oasis of the Seas

While both ships were built to the exact same specifications, technically the Allure of the Seas is 2.0 inches longer than the Oasis of the Seas. But, we’re including both as our Second Biggest Cruise Ship in 2019.

The Oasis was the first of the “Oasis Class” ships built in 2009 and truly broke the mold for huge vessels. Before the Oasis, nothing close to that size had been seen in passenger vessels.

Innovations never before seen were introduced with this class. Included was the “Rising Tide” bar, which spans three decks and the “Flowrider” surfing simulator. The ship offers unique neighborhoods that vary drastically, like Central Park, the Boardwalk, and the Royal Promenade.

The Allure was added to the Oasis class the following year in December 2010.

These ships raised the bar (figuratively and literally) for cruise ship innovation.

Oasis and Allure of the Seas Fun Facts

8,000 gallons of ice cream are consumed (serious brain freeze) each week on these ships. To power the Oasis Class ships, these vessels have over 3,000 miles of electrical wires. That would almost stretch the entire width of the United States! The bread you’ll eat at dinner is freshly made. There’s a machine in the kitchen area that bakes 4,000 rolls ever hour. While walking through Central Park on each ship, you’ll be surrounded by over 12,000 plants. During a weekly cruise, 60,000 napkins are used.

#4 – Largest Cruise Ship in the World: Costa Smeralda

The Costa Smeralda doesn’t have the most enticing name, but when you’re this big you can do whatever you’d like we suppose. In junior high school, there was a six-foot boy with a hint of a mustache named Francis and you best believe nobody made fun of him for it.

Costa is not known for its large ships so the Smeralda really puts them in the big leagues. And, when compared to the other massive vessels it has one special attribute that sets it apart from the others. Costa designed it to be powered on an LNG combustion system that makes it “the cleanest in the world.” Although, this feature won’t be entirely unique as you’ll see in our #4 largest cruise ship in the World.

The Cost Smeralda debuts in November 2019 and will offer itineraries within the Mediterranean shortly after.

#5 – Largest Cruise Ship in the World: AIDAnova

AIDA is another dark horse coming through with a huge ship out of the blue. Among their 10 other ships, the average size measures roughly 50,000 gross tons. The AIDAnova is over 3x their normal vessel weight size weighing in at 180,000 gross tons. Let’s hope the company knows how to handle all of that ship!

We’ll find out whether this is the case when the ship launches in December 2018. She’ll be serving up itineraries in the Canary Islands.

The AIDAnova will be a favorite of our environmentally conscious cruisers, as the ship is powered solely by liquified natural gas (LNG). It’s the very first ship to feature this eco-friendly fuel source.
