Even to this day, countless people remain fascinated by the RMS Titanic. This ill-fated and iconic vessel has captured people’s imaginations worldwide for over a century. While many details from the Titanic’s tragic maiden voyage are known to the general public, many people still wonder how and why the Titanic broke in half after colliding with an iceberg.

Today, we will explain why this famous ocean liner broke in half before it sank to the bottom of the North Atlantic Ocean. Not only will we explain how the collision caused the Titanic to break in half, but we will also cover some of the lessons learned from its sinking. 

So, if you are ready to uncover the truth about the Titanic’s final hours above water, it is time to get started!

On Sunday, April 14th, 1912, at approximately 11:40 p.m., four days into its maiden voyage, the Titanic struck an iceberg in the North Atlantic Ocean. Despite its tragic demise, the Titanic was painstakingly designed and built to be the most impressive and sturdy ocean liner ever made. So, why did it eventually break in half and sink?

Within minutes of the collision, the Titanic had already taken on thousands of tons of water through a significant hole in its hull. While passengers were largely unaware of what had occurred, the ship’s crew already knew there was a considerable chance that the Titanic would sink. Lifeboats were lowered less than an hour after colliding with the iceberg to allow women and children to escape the sinking.

The rapid flooding due to the breach in the Titanic’s hull ultimately caused the ship to break in half. As seawater flooded into the Titanic, it began filling various compartments throughout the ship’s lower decks.

Given that the Titanic was over 882 feet long, the imbalance caused by the immense weight of the water-filled compartments put an incredible amount of stress and pressure on the ship’s already compromised hull.

At 2:17 a.m., just over 2 hours and 40 minutes after the initial collision, the Titanic’s hull began breaking in two.

While the incredible weight of the seawater that the Titanic took on due to a breach in its hull would be enough to sink most ships of its time, it would not necessarily be enough pressure to cause the ship to break in half. The break had a lot to do with the ship’s immense size and an overlooked vulnerability in its design.

The split in the Titanic took place between the ship’s third and fourth funnels, which were giant smokestacks that supported the immense steam engine. Unfortunately, this part of the Titanic’s hull was slightly weaker than other areas, as the design could not accommodate a much-needed expansion joint due to the weight of the funnels. 

Since it was weaker than other hull parts, this part of the ship lacked the structural integrity required to support the added weight of flooded compartments. The pressure on the weakened section of the ship eventually caused it to snap in half.

While it is often seen as one of the less important factors for splitting the Titanic, recent research claims that the ship’s steel hull and wrought iron rivets proved brittle when they faced the forces generated by impact with the iceberg.

While the materials seemed durable enough to withstand an impact in ideal conditions, the water in the North Atlantic Ocean was well below freezing. The steel the hull was constructed from contained high levels of sulfur, which meant it was weakened when chilled to low temperatures. Modern-day microstructural analysis of hull steel recovered from the wreckage site has proven that there might be some plausibility to the brittle steel theory.

If you have seen James Cameron’s film Titanic, you will have noted that the ship breaking in half was depicted as one of the most dramatic and chaotic moments of its sinking. The truth is, it is not fully known how consequential this event was. 

In fact, whether or not the breakage accelerated the sinking and led to a more significant loss of life continues to be questioned by experts today.

While some experts argue that the break would have caused the ship to begin sinking faster, as it would have released trapped air within non-flooded compartments in the ship’s lower decks, others believe that the Titanic was sinking at a set speed. The breakage would have had a negligible impact. 

One thing is for sure; the breaking would have been a heart-wrenching sight, especially for those witnessing from lifeboats who still had loved ones trapped within the confines of the doomed ship. This would have been more traumatic given that survivors were told for nearly 70 years that they were mistaken in what they claimed to have seen.

Until the Titanic’s wreckage was explored in 1985, many experts argued that it would have been impossible for the ship to have split in half above the water.

While the sinking of the Titanic is interesting in its own merit, it has had a particularly influential impact on maritime safety standards and regulations.

The cause of the Titanic’s sinking and the event’s timeline triggered the establishment of the International Convention for the Safety of Life at Sea (SOLAS) in 1914, less than two years after the ship sank. This introduced stricter safety standards for all ships, especially passenger-carrying ocean liners.


The primary goal of SOLAS was to establish legally binding safety standards for constructing all passenger vessels. This means using higher-grade materials in construction and having all designs approved by qualified professionals. Given that the sinking of the Titanic was even more tragic and costly due to the mismanagement of safety equipment, SOLAS also aimed to standardize the presence and use of safety equipment on all passenger ships. 

According to the 1914 version of SOLAS, all ships had to carry a sufficient number of lifeboats for the ship’s passengers. The standards for safety and evacuation drills were also made much stricter. It also introduced new standards for fire safety and watertight compartments.

Finally, the SOLAS agreement that emerged in the aftermath of the sinking also standardized communication and navigation equipment requirements to avoid collisions like that which claimed the Titanic.

While the SOLAS convention of 1914 introduced massive changes in standards for maritime vessels of the time, it has since undergone numerous updates and revisions. As recently as September 2021, SOLAS 2020 was released. In many ways, the sinking and breaking of the Titanic have had a lasting impact on safety standards even today. 

Beyond SOLAS, the breakage of the Titanic also resulted in new standards and manufacturing processes for shipbuilders worldwide. No shipbuilder wanted to be responsible for sinking on the scale of the Titanic.

If you are worried about safety standards on a modern cruise ship and whether or not one could suffer the same fate as the Titanic, you will be relieved to discover that advancements in ship design and safety standards have made them far more resilient. The truth is there is very little chance that a modern cruise ship would break in half, even in the extremely unlikely event that it was sinking.

Even if a modern-day cruise ship collided with an iceberg or another solid object, improvements in design, construction, and safety measures would mean that the ship would not sink, never mind actually breaking in half. 

Here are some of the ways cruise ships today are not vulnerable to hull-splitting incidents that claimed the Titanic.

Today, cruise ships are constructed with reinforced hulls free from weak points that contributed to the breaking of the Titanic. They are made from more advanced and durable materials and are now engineered to distribute pressure and external stress evenly across the ship’s hull and keel. This improves the overall strength and stability of the entire ship. 

While the Titanic was divided into compartments that were designed to be watertight, they could not withstand the immense pressure generated by seawater flooding into them. This allowed flooding to spread and increased the speed at which the ship’s lower decks filled with water. Eventually, this flooding caused the ship’s hull to break into two.

Modern cruise ships now use far more sophisticated compartmentalization procedures that help contain flooding to specific areas of the ship. Lower portions of the ship can be sealed off manually or through an advanced computer system that can automatically detect flooding. 

As discussed above, cruise ships now adhere to a wide range of maritime safety regulations that dictate how the vessel can be designed and must be operated at sea. This ensures that all cruise ships maintain the same high passenger and crew safety standards.

Advancements in technology, like computer monitoring systems that detect even the slightest issues related to structural integrity, ensure that the crew can react well before an emergency. Modern navigation equipment also helps the ship’s crew avoid collisions that resulted in the Titanic’s tragic sinking. 

Even beyond safety standards and ship design, the Titanic differs significantly from a modern-day cruise ship. Even the passenger experience was widely different. 

While it is difficult to gauge the precise timeline of the breakage, most modern estimates put it at roughly 2 hours and 40 minutes after the ship’s collision with the iceberg. After the Titanic had broken in half, it is believed that it took approximately 10 minutes for the bow and stern sections to submerge fully. 

Yes, once the Titanic had broken in half, it became challenging for anyone to evacuate the ship. Not only did it increase the speed at which the ship sank, the splitting would have made it highly confusing and stressful for anyone unfortunate enough to be still on board the vessel. 

There are no other records of ocean liners breaking in half due to an accidental collision with an object. With that said, during wartime, particularly the First World War, numerous merchant and navy vessels split in half due to direct hits from torpedoes and other weapons. 

In peacetime, the type of catastrophic breakage that finished the Titanic off has not been seen. This is partially due to the advancements in safety standards and ship design that emerged after the Titanic’s sinking. 

While the Titanic’s tragic maiden voyage certainly stands as a stark reminder of the dangers the oceans can pose to even the most impressive man-made vessels, the ship’s sinking and breakage resulted in some of the most important safety innovations of all time. 

Today, passenger vessels are made to withstand and avoid collisions that caused the Titanic to split and eventually sink. Without the sinking, it may have taken decades longer for something like the SOLAS agreement to emerge, which could have resulted in countless other incidents and lost souls at sea.
