Rogue waves are abnormally large and unpredictable surface waves. While rare, these formidable ocean waves occasionally impact cruise ships and other large vessels at sea.
Fortunately, the cruise ships of today are engineered to protect passengers and withstand the challenges these waves pose, so damage tends to be minimal.
This guide will explain what you can expect in the unlikely event your ship is impacted, the emergency systems used to protect passengers, and more.

What Is a Rogue Wave?
A rogue wave is a large, unexpected ocean wave that usually appears with little warning, even in seemingly calm waters. These waves, also referred to as walls of water, freak waves, or even killer waves, are different from tsunami waves, which result from major seismic events, like underwater earthquakes, landslides, and volcanic eruptions.
By definition, to be characterized as a rogue wave, the wave must be at least 2.2 times larger than the average, but it can be significantly taller and wider than that.
Rogue waves are not triggered by seismic activities but can result from natural ocean dynamics and unpredictable weather conditions, such as major storms. When underwater currents and surface-level winds occur simultaneously, their combined energy can create an abnormally large and powerful single wave.
While they can occur in just about any large body of water, they are far more likely in areas where strong ocean currents are exposed to strong winds, like the Agulhas Current off the coast of South Africa or the Gulf Stream in the Atlantic Ocean.
While their very nature makes rogue waves difficult to predict, modern satellite technology and weather forecasting equipment have improved the ability to track the waves.
That said, they can quickly appear in the open ocean, making them a major challenge for any large vessel traversing these waters, including cruise ships.
With how powerful and unpredictable these waves are, the modern cruise and shipping industries have reacted by putting efforts into tracking and avoiding them, as well as withstanding them in the event they cannot avoid a towering wave.
What Happens When a Rogue Wave Hits a Cruise Ship?
In the event that a cruise ship can’t avoid a rogue wave and is forced to come in direct contact with one, the impact can be substantial and alarming for both passengers and the ship’s crew.
This is because the waves can hit with immense force, which, in some cases, can cause structural damage to the ship itself. With that said, modern cruise ship design helps minimize the impact of these events and how noticeable and chaotic the impact is for those on board the ship.
Even if a massive rogue wave breaks against a cruise ship’s bow, the reinforced hulls and windows are designed to withstand the impact, preventing water from flooding into interior spaces.
For onboard passengers, the most forceful rogue wave impacts usually just result in sudden jolts, where some unsecured items can rattle and fall over.
In the most severe cases, the ship may tilt to one side temporarily or even experience a short power outage. In these cases, the cruise ship’s emergency systems and stabilizers kick in to minimize the impact of the rogue wave or waves.
While serious instances of a cruise ship’s physical integrity being compromised and passengers being injured are incredibly rare, there have been a few notable incidents in the past.
Notable Incidents
As mentioned, incidents where cruise ships are actually damaged and their crew and passengers are put in serious danger are exceedingly rare, but the following incidents have occurred:
Viking Polaris Incident (December 2022)
While voyaging from Ushuaia, Argentina, to Cape Town, South Africa, Viking Polaris was struck by a massive rogue wave in the particularly dangerous Drake Passage, just south of Cape Horn.
Tragically, the impact resulted in the death of one passenger, as well as injuries to several other passengers. Despite the incredible force of the wave, the Polaris’s structural integrity remained intact, allowing the ship to return to port under its own power and without the need for a tow or passenger evacuation.
While this incident had a tragic result, the estimated 25-foot-tall wave height could have devastated the ship if it had not been designed to withstand these enormously powerful impacts.
Royal Caribbean Explorer of the Seas Incident (November 2024)
More recently, Royal Caribbean’s Explorer of the Seas encountered a massive rogue wave while undergoing a trans-Atlantic voyage from Barcelona, Spain, to Miami, Florida. While the ship was able to withstand the wave itself, a deadly storm delivering hurricane-force winds caused the ship to tilt.
Although the ship was able to complete its voyage, the tilt caused by the combined impact of the enormous wave and powerful winds did cause minor injuries to some passengers.
However, thanks to the ship’s engineering and stabilizer system, the frightening experience only lasted a short period, and aside from a few minor cuts and bruises, the passengers completed their itinerary without any major delays.
While these incidents are certainly alarming, especially for those who experience them firsthand, it’s important to remember that they are incredibly rare.
Today, cruise ships are designed to withstand these types of impacts, and equally importantly, they also have sophisticated weather detection and communications systems that allow them to avoid the type of weather and ocean current events that cause them.
Can a Rogue Wave Sink a Cruise Ship?
We’ve all seen movies like Titanic, so it’s no wonder that one of the most common fears amongst cruise ship passengers is an event powerful enough to sink the ship they are traveling on.

Luckily, the answer to whether or not a rogue wave could do so is almost certainly not. This is because modern cruise ships are designed with multiple layers of safety nets and systems that allow them to traverse through even the most extreme weather conditions and waves.
These key safety features include the following and more:
Structural Integrity
Today, modern cruise ships are built with reinforced hulls designed to withstand even the most forceful waves. These hulls are reinforced with heavy steel, which not only ensures they are strong enough to withstand direct impacts but also makes the ship immensely heavy, which makes it more stable.
Weight is also distributed carefully to optimize buoyancy, while ballast systems and stabilizers help keep the ships upright in even the most violent waters.
Cruise ships are also designed to have a low center of balance, which prevents them from tipping over.
Advanced Navigation
Cruise lines also use sophisticated, state-of-the-art navigation and weather detection systems to avoid areas with heightened wave activity. This equipment allows them to alter their planned sailing route to avoid potential dangers, minimizing the risk of encountering rouge waves and disrupting passenger comfort.

For example, a cruise ship headed toward Norway to explore the fjords might reroute to bypass the region if its satellite weather detection systems detected or predicted extreme storm waves or even unexpected wind gusts that could trigger the formation of these dangerous rogue waves.
Crew Training and Emergency Protocols
Beyond the physical design of cruise ships and the sophisticated weather detection systems they are equipped with, the cruise industry also relies on well-trained crew members who can implement emergency systems and drills to ensure every passenger is safe in the event of an unavoidable rogue wave or other challenge.
In these situations, the crew directs passengers to their designated muster stations and, if necessary, distribute life vests. All of these emergency protocols are supported by regular safety drills and rigorous measures to ensure the entire crew understands their role in the event of an emergency.
While each cruise line has its own safety protocols, these are also supported by mandatory measures enforced by maritime authorities.
While Mother Nature can be unpredictable, the sophisticated combination of modern ship engineering, advanced technology, and well-drilled crew expertise ensures that rogue waves pose as little risk as possible to cruise ships and their passengers.
Even passengers must complete safety training and muster drills to prepare for the most unlikely emergencies.
What Do I Do if My Cruise Ship Is Hit by a Rogue Wave?
In the unlikely event that your cruise ship encounters a rogue wave, you must stay calm and pay attention to the instructions provided directly by the crew or the ship’s internal communications system.
After spending 8 years working on cruise ships, I know how important it is to follow their lead in these situations. Here are a few tips you can follow to make sure you are safe if an unlikely rouge wave situation does occur:
Stay Indoors
Remaining inside the ship is the safest place if your ship encounters any turbulent waters. If you can, try to stay away from any objects that could become dislodged if the ship began rolling. Grabbing hold of a secure and stable object can also help if you have concerns that the ship’s motion could knock you down.
If you find yourself on one of the ship’s outer decks or even your own private balcony, move indoors as quickly as possible. Again, you will be much safer inside the ship than in an outdoor area.
Always Follow Crew Instructions
No matter what type of situation is unfolding, it is always important to closely adhere to any instructions provided by the crew. The crew of your cruise ships are thoroughly trained to ensure they understand what to do in any emergency.

If you are not speaking directly to a crew member, listen for announcements over the ship’s PA system and follow those directions.
Report Any Injuries or Damage That You Notice
After the incident, it is always a good idea to report any injuries you or a fellow passenger has sustained to the crew. They will be able to ensure that all passengers receive the required medical attention as quickly as possible.
Any damage you notice to the inside of the ship should also be reported, even if it seems relatively insignificant. Even a loose mirror or shelf can be dangerous if not secured.
Remember, the likelihood of experiencing a rogue wave is minimal, and cruise lines prioritize passenger safety with comprehensive emergency protocols.
Final Thoughts on Rogue Waves and Cruising
While the idea of being on a cruise ship when it encounters a rogue wave may seem pretty scary, it is essential to remember that these events are incredibly rare. In all my years of cruising, I have never personally encountered more than small waves that have no serious impact on the ship itself.
