However, in today’s times, it is unlikely for something like that to happen to a cruise ship that’s hit by a large wave. In huge water transportation such as a cruise ship, you will want little wave movements to keep things on the upper decks as steady as possible. While it’s not uncommon for cruise ships to tip to one side (no matter how far off to one side), they are designed in such a way that they won’t tip over.

Cruise lines prioritize safety by taking all necessary precautions to prevent accidents and guarantee the safety of their passengers and crew. The MS Estonia was a passenger and car ferry that capsized and sank in the Baltic Sea on September 28, 1994. The ship was on its way from Tallinn, Estonia, to Stockholm, Sweden, when it encountered rough seas and high winds. Cruise ships are designed with multiple decks and heavier components on the lower decks.
Cruise Ships Have Ballast Tanks
Bilge keels look like two fin-like structures running along the center of the cruise ship’s hull for about two-thirds of its length. The center of buoyancy is the center of the cruise ship underwater. The center of gravity of a cruise ship can be controlled by increasing or decreasing the weight of the ship. While it is not impossible, It is extremely unlikely for a cruise ship to tip over even if it encounters some of the roughest seas on earth. So let’s look at the critical design elements that keep a cruise ship upright and stop it from tipping over.
Celebrity Cruises
Cruise Radio prioritizes well-balanced cruise news coverage and accurate reporting, paired with ship reviews and tips. Cruise ships can and have tipped over, but it is extremely rare. One of the most notable incidents was the capsizing of the Costa Concordia in 2012, which resulted in the deaths of 32 people. The accident was attributed to human error and resulted in many changes within the industry, particularly in bridge management. The ship hit a rock due to the negligence of the captain and took on water, causing it to fall to one side and eventually capsize.

Ballast is located at the bottom of the ship and can be transferred from side to side to help maintain the ship’s balance. Cruise lines can use seawater or fuel for stability during sailing. One of the most important features is the ship’s center of gravity. The center of gravity is where the ship’s weight is evenly distributed. The cruise industry hosts over 20 million passengers annually on hundreds of cruise ships.
The hull is made from heavy steel and contains incredibly dense machinery and fuel tanks. On the other hand, the top section of the ship is far less dense and tends to be made from lightweight and durable materials, like aluminum. So, if you’ve ever been worried that your cruise ship might tip over in bad weather, you really don’t need to. The bottoms of cruise ships are not flat near the bow nor at the raised area at the stern where the propellors are. As an additional benefit, the smooth ride helps to prevent motion sickness on a cruise ship.
And when it comes to human error, statistics show that this is more often than not the passengers’ fault. Archimedes’ principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid. Ship hulls are constructed from lightweight and sturdy materials. If they release the water, the tanks fill with air, and the submarine rises.
Weight Distribution
The weight of the ship is distributed throughout the hull, with the heaviest parts located at the bottom and the lightest parts at the top. The materials used in the construction of a cruise ship also play a crucial role in its design. Many modern cruise ships are constructed using aluminum, which is lightweight and strong, allowing for greater speed and fuel efficiency. The use of aluminum also reduces the overall weight of the ship, which enhances its stability. The biggest mystery for some people is how does that big guy stay afloat and avoid Keeling over?
Alternatively, you can have the charges added to your room bill on board. The extra cost of the automatic gratuity charges can be a shock to first-time cruisers. And, unlike the typical service fee or resort fee found at a land resort, they are not per room. How much to tip on a cruise is a question that trips up many first-timers.
A cruise ship’s centre of gravity can be moved up or down by adjusting weights within the vessel – the most obvious is ballast water and fuel. In extreme cases, cruise ship swimming pools could be drained to provide additional stability, as the weight of so much water on the upper decks will make the centre of gravity higher. Cruise ships can avoid tipping over thanks to the combination of the ship’s wide hull, low center of gravity, ballast tanks, and stabilizers. These contain water that can be pumped from both ends of the ship as needed to maintain its overall stability. These ballast tanks, in effect, allow the weight of the ship to be controlled and stabilized. They control the weight of the ship and lower its center of gravity, keeping it stable.
In general, ships are designed to have a certain maximum heel angle, known as the “angle of loll,” beyond which they become unstable and are at risk of capsizing. In both of these cases, however, the ships were able to stay afloat and evacuate passengers and crew members safely. In fact, according to the New York Times, there were only 16 ships that sunk between the years 1980 and 2012. Here’s a closer look at how cruise ships are designed and built to stay upright, as well as five surprising facts about their stability and seaworthiness. Dynamic stability is the ability of the ship that make it stable and prevent it from tipping under external forces.
The ship ran aground off the coast of Italy, resulting in 32 deaths. This tragedy serves as a reminder of the importance of safety and maintenance in the cruise industry. By reducing the amount of energy needed to keep the ship moving, stabilizers can help to save fuel and reduce the ship’s carbon footprint. Keep in mind that there are some services provided by non-cruise staffers for which tips should also be paid out of pocket -- this extends to port-side baggage handlers or shore excursion tour operators.
