Or perhaps another ship in the area sends out a distress signal and your cruise ship is the closest vessel that can help. Eventually, one “knot” came to equal one nautical mile per hour. A land mile covers 5,280 feet, while a nautical mile covers 6,076 feet — a difference of 15%.

So, How Fast Do Cruise Ships Go?
Now, let’s take a futuristic glimpse at the world of cruise ship speeds. With new technological advancements popping up faster than the bubbles in your average cruise ship with champagne, the horizon of cruising speed is set for a shakeup. Before we start, it’s essential to understand that the speed of ships is measured differently than we’re used to on land.

I worked as an officer in the deck department on various types of vessels, including oil and chemical tankers, LPG carriers, and even reefer and TSHD in the early years. Currently employed as Marine Surveyor carrying cargo, draft, bunker, and warranty survey. She has worked in the cruise industry since 2015 and has taken over 30 cruises. Now, she helps over 1 million people per month to plan their perfect cruise holidays. Although the ship has been retired since 1969, there’s talk of reviving this speed demon and bringing it back into active service. Aero derivative gas turbine engines turn heat into mechanical energy, which then is transformed by a turbine into electrical energy.
Factors Influencing Cruise Ship Speed Selection
Another factor that influences speed selection is fuel efficiency and environmental considerations. Operating at a certain speed can optimize fuel consumption and reduce greenhouse gas emissions. Cruise lines strive to find a balance between fuel efficiency and journey time, ensuring a sustainable and environmentally responsible approach to cruising.
What is the average cruise ship speed?
Their engines produce about 3,500 horsepower each giving them enough energy to propel the ship at a steady pace. Some newer models boast even higher speeds such as those found onboard the Pacific Aria. First up, let’s pay our respects to the fastest cruise ship of the Queen – Queen Mary 2, that is.
Many people consider the fastest cruise ship to be Cunard’s Queen Mary 2, which has a top speed of 30 knots. But, the Queen Mary 2 isn’t actually a cruise ship – it’s an ocean liner. Efficient fuel consumption and environmental sustainability are significant considerations in the speed selection process. Furthermore, environmental considerations play a significant role in speed regulations. Cruise lines are committed to minimizing their carbon footprint and reducing emissions.

Now, the speed of most cruise ships isn’t just a “one knot fits all” deal. Everything from the ship’s design, the weather (rough seas require slower speeds), and even fuel efficiency come into play. It’s a delicate dance, or should we say, a well-coordinated sea shanty of factors that keeps these vessels smoothly sailing to your next port of call.
This is where cruise lines can tweak the ship's design or structure as needed. A racing sailboat can reach up to 15 knots, but a regular sailboat moves at much slower speeds, usually only 4 to 6 knots. While a cruise ship will take you to specific cruise destinations, it usually ends where it began. If your cruise ship travels from Port Canaveral, it will head back there at the end of the trip.
Faster Ships
The measurement of miles on land dates back to Roman times and is based on 1,000 paces (only counting the left foot). Nautical miles were defined much later, in 1929, and are based on degrees of latitude around the earth. Aero derivative gas turbine engines and diesel-electric engines both rely on super-heated air to combust. Any decisions to speed up or slow down are always made with everyone’s safety and comfort in mind. Meanwhile, ships that sail to Antarctica or through Alaska’s Inside Passage may need to adjust their speed if there are glaciers or icebergs in the area.
Just like cars and boats, larger ships require more power to move through the water, which can limit their speed and range. The heavier the ship, the more force is required to accelerate it, resulting in increased fuel consumption. Therefore, larger ships tend to have a slower cruising speed compared to smaller vessels. Well it really depends what class of cruise ship you are talking about. The 25,000 ton Olympia Voyager (aka Costa Voyager, Voyager, and Grand Voyager and now owned by Bohai Ferry Company) can travel as fast as 27 knots or 31 miles per hour. But 25,000 tons is very small by the standards of today’s cruise ships, and the Voyager is really an ocean liner and not a cruise ship.
Most cruise ships are powered by diesel electric engines or gas turbines, and they have propellers that cut through the water to move them forward or backward. The speed of a cruise ship is dependent on the power output of its engine as well as its size and weight. By optimizing speeds, cruise lines can enhance fuel efficiency, reducing both operational costs and environmental impact. Operating at the most fuel-efficient speed can result in significant savings for cruise lines in terms of fuel consumption, which is typically one of their largest expenses. Additionally, reducing fuel consumption contributes to the preservation of natural resources and helps minimize greenhouse gas emissions.
Typically, the Azipods all point in the same direction, towards the ship’s stern, which propels the ship forward. However, captains can adjust the amount of thrust and the direction of each pod, allowing the vessel to turn or even travel in reverse. Of course, putting a massive cruise ship in reverse is a bit different than backing up your car. Before going any further, it’s crucial to understand how speed is measured on water. "The real objective is to go 18 or 19 knots much more efficiently, (and) the thing that makes it able to do that also makes it faster." It might not be operational, but its previous accolades make it the fastest passenger vessel currently afloat.
In order to measure a ship's top speed, they calculate an average that takes into consideration going with and against the waves in the ocean. The weather plays a major role in how fast a ship could travel, just like how an airplane's top speed can depend on how strong of a tail or headwind it encounters. In short, the number of knots pulled out into the water over a specific period of time translated into the speed of the vessel's travel. In the 17th century, ship crews measured vessel speed by tossing a rope with several evenly spaced knots and a triangular-shaped piece of wood into the water.
To maintain a smooth and comfortable ride, cruise ships employ advanced stabilization techniques. Modern cruise ships use stabilizers, such as fins and gyroscopic stabilizer systems, to counteract the effects of waves and minimize the ship’s rolling motion. These technologies help ensure a steady speed and a more enjoyable experience for passengers.
