Visualized: Comparing the Titanic to a Modern Cruise Ship

Remembering the Tragedy of the Titanic

When the Titanic was completed on April 2, 1912, it was the largest and perhaps most luxurious ship in the world. The vessel could hold over 3,300 people including crew members, and boasted various amenities including a swimming pool and squash court.

The Titanic’s impressive size attracted many of the world’s wealthiest individuals, and on April 10, 1912, it set out on its maiden voyage. Just five days later, the ship sank after hitting an iceberg, resulting in more than 1,500 deaths.

It’s been over 100 years since the Titanic’s demise, so how have passenger ships evolved?

To find out, we’ve visualized it beside Royal Caribbean’s Symphony of the Seas, currently the world’s largest cruise ship.

The Size of the Titanic, in Perspective

The following table lists the dimensions of both ships to provide a better understanding of the Titanic’s relative size.

	RMS Titanic	Symphony of the Seas
Year Built	1912	2018
Length	882ft (269m)	1,184ft (361m)
Width	92ft (28m)	215ft (66m)
Height	175ft (53m)	238ft (73m)
Internal volume	46,328 gross register tonnage (grt)	228,081 gross tonnage (gt)
Passengers	2,435	6,680
Crew	892	2,200

Note: Gross register tonnage (grt) is a historic measure of a ship’s internal volume. This metric was replaced by gross tonnage (gt) on July 18, 1982.

One of the biggest differences between these two ships is width, with the latter being more than twice as wide. This is likely due to the vast amenities housed within the Symphony of the Seas, which includes 24 pools, 22 restaurants, 2 rock climbing walls, an ice-skating rink, and more. With accommodations for 6,680 passengers, the Symphony of the Seas also supports a crew that is 147% larger.

The Symphony of the Seas clearly surpasses the Titanic in terms of size, but there’s also a substantial difference in cost. When converted to today’s dollars, the bill for the Titanic equates to roughly $400 million, less than half of the Symphony of the Seas’ cost of $1.35 billion.

Lessons Learned from the Disaster

Inadequate safety preparations were a contributor to the Titanic’s high death toll. During its journey, the vessel carried enough lifeboats to accommodate just 33% of its total passengers and crew. This was legal at the time, as regulations based a ship’s number of required lifeboats on its weight, rather than its passenger capacity.

To make matters worse, investigations determined that the Titanic’s lifeboats had not been used to their full capacity, and that a scheduled lifeboat drill had been cancelled by the ship’s captain. These shortfalls, among others, paved the way for numerous improvements in maritime safety regulation.

These include the creation of the International Convention for the Safety of Life at Sea Treaty (SOLAS) in 1914, which is still in force today. Regarded as the most important international treaty on ship safety, SOLAS has been updated numerous times and is followed by 164 states, which together flag 99% of merchant ships (by gross tonnage) on the high seas today.
