Knots are preferred in sea and air navigation as they align with Earth’s latitude, making them more practical for long-distance travel where Earth’s curvature matters. Cruise ship captains earn an average annual salary of $54,541, with top earners making $79,500 per year. The Ultimate World Cruise offered by Royal Caribbean is a 274-night journey that visits all 7 continents, 65 countries, over 150 ports of call, and 11 World Wonders. They tend to have a longer, pointed bow that helps them navigate high rising ocean waves.
How Fast Do Cruise Ships Sail? The Answer Might Surprise You…
In return for it, drafts of ft (7-9 m) allow smooth rides when traveling even with mph (over 40 kph). In 24 hours, a cruise ship travelling at the standard service speed can cover about 480 nautical miles (which equates to 552 land miles). While visibility is obviously reduced in the dark, cruise ships have equipment that means that they can look out for hazards, even in the dark. Cruise ships need to strike a balance between speed and fuel efficiency. The faster a ship travels, the more fuel it consumes, which can significantly increase operational costs.

Depending on your vantage point, it could feel like you are sailing at a very fast speed onboard a cruise ship, gliding through the endless blue sea. For these reasons, cruise ships mostly operate at a standard cruising speed that strikes a balance between safety and efficiency. There can be many reasons why a cruise ship slows down, and it's not just to save fuel. Certainly fuel consumption can play a major role in determining what speed to travel at, but other conditions can dictate a slower speed. Not only do cruise ships rarely travel at their fastest speed, but they often go much slower.
Understanding Ship Speed
The QM2 is the only transatlantic cruise ship currently in operation, and it offers one annual cruise that crosses the Atlantic. The mega-ship is still the largest ship under commission, with a service speed of 26 knots. While you are free to do what you want, when you want while on a cruise, the ship itself is on a schedule. It has arrival times and departure times that it needs to keep.

Nautical miles were defined much later, in 1929, and are based on degrees of latitude around the earth. At full capacity, the ships can hold nearly 6,700 passengers and 2,200 crew. In other words, on a single ship you can have nearly 10,000 people at a single time.
Cruise ship speed (knots to mph/kph conversion)
Here's everything you may have wondered about cruise ships and their speeds. If you have seen a modern cruise ship up close, they are quite large and can move from port to port, and even continent to continent. To move a ship as large as Royal Caribbean's Oasis Class cruise ships requires a combination of power generation and efficiency. After all, the easier something is to get going, the less energy required overall. This actually makes much more sense than statute miles, which are based on 1,000 times the length of two strides.

From this information, the computer calculates the ship’s velocity. If the ship has been stationary for more than five minutes, its speed is calculated from the last known location. Otherwise, the computer uses data collected during previous trips to estimate the ship’s current speed.
Cruising Speed of Some Popular Cruise Ships
Similarly, a ship's displacement, condition of the hull and propeller, or draft can all factor into a ship's top speed. 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.
However, captains can adjust the amount of thrust and the direction of each pod, allowing the vessel to turn or even travel in reverse. In the post-war years of World War II, many ocean liners were competing to cross the Atlantic in the shortest amount of time. These propellor systems turn “screws” instead of long propellors like a plane. These screws need a lot of torque, instead of a lot of high-speed to operate. Cruising speed also improves fuel efficiency, the same way a certain speed improves fuel efficiency for your car. You may be able to drive your car at 80 MPH on the highway, but you’ll burn through a lot less gas if you drive at a steady 65 MPH.
We’ll talk about the different variables that affect speed and see how cruise ships compare to other ocean-going vessels. In short, the cruising speed of a ship dramatically depends on the ship’s size and design. The ship’s structure will determine how it burns fuel and how it navigates changing ocean conditions, all of which affect its speed. See here to learn more about the differences between ocean liners and cruise ships. Depending on the weather and other factors, a ship may take longer to travel 480 nautical miles.
Another factor that affects the speed of a cruise ship is the water and weather conditions. The force and direction of the wind can either work with or against the ship, impacting its speed. If the ship is facing strong headwinds, it will require more power and fuel to maintain speed. Additionally, rough seas or navigational hazards such as icebergs can also slow down a cruise ship. Captains may choose to reduce speed for safety reasons, ensuring a smooth and comfortable journey for passengers. In truth, a cruise ship’s speed depends on the design of the ship, the itinerary, and the weather.
For example, front-loading the boat creates drag and slows it down. In general, cruise ships up to 1,100 feet long must carry as much as two million gallons of fuel to make the trip between ports of call. In comparison, a private motor yacht that’s 60 feet long carries up to 1,200 gallons while the Exxon Valdez holds 55 million gallons of fuel. Launched in 1969, Cunard’s Queen Elizabeth 2 faithfully toted passengers until it was decommissioned in 2008. The QE2 was intentionally built to be the world’s fastest passenger ship.
Therefore, one knot equals about 1/5th of a nautical mile per hour. Since a nautical mile is equal to 6076 statute miles, one knot represents just shy of 2% of a statute mile per hour. Nautical miles are the preferred measure of distance at sea because they allow sailors to quickly access distance on nautical maps which use longitude and latitude. On the flip side, nautical miles, established in 1929, are tied to the Earth’s latitudinal degrees – one nautical mile equals one minute of latitude. For starters, we are seeing the dawn of a new era with the introduction of LNG-powered engines.
While doing so, you’ll visit some amazing cities like Rome, Venice and Athens. First, you must determine how much extra power you need in order to increase your speed beyond what is normally required. Then, you must find ways to add that amount of power to your existing engine system.
The design of the ship’s hull also plays a critical role in determining its speed. Cruise ships have displacement hulls, which are designed to push water out of the way as the ship moves forward. The hull design affects how efficiently the ship moves through the water and can impact its speed and fuel consumption.
So while the thought of sailing on the fastest cruise ship in the world may be exciting, cruising is more about relaxation, leisure, and exploration. Whether you’re enjoying the amenities on board or exploring the ports of call, it’s the journey itself that makes cruising such a memorable experience. When it comes to cruise ships, speed is not always the top priority.
