What keeps a large cruise ship from tipping over?

Thanks to sophisticated stabilization systems, modern cruise ships can ensure stability and avoid tipping over. Some of these systems, known as active stabilization systems, adapt to water and weather conditions. Gyroscopes, thrusters, and counterweights prevent the ship from swaying in the water.

Gyroscopes, thrusters, and counterweights prevent the ship from swaying in the water. By reducing rolling and pitching, they maintain a stable experience for all passengers and crew on board the vessel, but, more importantly, they prevent the ship from tipping over, even in the roughest waters.

A whale could not tip over a cruise ship. Although even the largest of blue whales can weigh up to 200 tonnes, the largest cruise ships can weigh up to 220,000 or more. Some cruise ships would carry ten times more freshwater or fuel than the weight of even the largest whales.

A 2022 study found that out of 49 attacks that year, whales damaged ships in about 73% of interactions. And 25% of those had to be towed back to port. The study's author told Live Science that whales target about one out of every 100 ships passing around the peninsula.

Although rare, cruise ships can technically tip over. But will they? Highly unlikely. According to Harry Bolton, retired captain at the California Maritime Academy, a cruise ship could hypothetically tip if it were in extreme weather, positioned sideways, and rolled over by a 70 to 100-foot wave.

Yes, cruise ships have brigs, which is the nautical term for a jail on a vessel, including a cruise ship. The term comes from the word brigantine, which is a type of two-masted sailing ship formerly used to house criminals.

Cruise ships are made of heavy steel, making them quite weighty. Add passengers and crew, and the ship is even heavier. With all this weight, the vessel can easily roll through rough waters or a rogue wave. It's more dangerous to be on an empty ship as the additional weight acts as a balancer in rough seas.

As soon as an incident happens, cruise ship crew will activate a button that pinpoints the place where the person went into the water. The ship will then stop and turn back to that area. The ship and its crew will perform a lengthy search and rescue operation, lasting several hours.

Around 10% of a cruise ship is below the water. Some of the largest cruise ships in the world, Royal Caribbean's Oasis-class ships, have a height above the waterline of around 72 metres (236ft 11in), and a draft below the water of around 9.3 meters (30ft 6in).

Over the past 100 years since the RMS Titanic sank in 1912, only 18 cruise ships and some ocean liners have been publicly known to have sunk. And, over the past 50 years, only four cruise ships have sunk while navigating on a cruise.

Do you know how much a modern cruise ship can roll before it capsizes? Up to 60 degrees according to experts, which is 3 times more than this picture.

In general, cruise ships are pretty safe. It's extremely rare to have a disaster occur like the Costa Concordia back in 2012 when the Italian vessel drifted off course, ran aground, and capsized.

Earthquakes are known to trigger tsunamis, posing another potential hazard to passengers at sea. However, whether a cruise ship is in any danger largely depends on its location. Experts agree that a cruise ship sailing out over a body of water is not likely to feel any impacts from a tsunami's waves.

You can see many animals from all species on a cruise ship that you simply can't find as easily on a land-based trip. The ocean alone is a perfect place to see cute animals - take a long look at the sea next time you're on a cruise, and you might be lucky enough to see dolphins, whales, flying fish or seagulls.
