If there’s a driving tailwind, the captain may choose to reduce the engine power to avoid arriving at the next port too early. The knot is a nautical term, meaning cruising one hour the distance of one nautical mile. And one nautical mile (by the contemporary world standards) equals 1,15 statue (or "land") miles (6,080 "modern" feet) or 1,852 kilometers. So, to convert the speed values of ships (and riverboats, and of whatever floats) simply multiply knots by the above constants. Worldwide, the knot speed measuring is also used in meteorology and air navigation. Cruise ship average speed is affected by lots of outside forces, as mentioned above.
Why Cruise Ships Measure Speed in Knots (and How to Convert It)

High-speed cruise ships excel in covering longer distances efficiently, while slow-speed cruise ships prioritize scenic cruising, extended port visits, and serenity. Slow-speed cruise ships provide a counterpoint to the fast-paced world we often find ourselves in. They appeal to those seeking a slower, more leisurely pace, allowing them to savor every moment of their cruise vacation.
How fast do cruise ships go?
Larger ships are generally slower and consume more fuel than smaller ships. Thankfully, emergencies don’t happen all that often on the high seas aboard a cruise ship. If someone falls off the boat, the ship has to slow down and turn around to attempt to rescue. Sometimes, another vessel requires assistance, and the crew prepares the boat for top speed to answer the SOS. In case of an outbreak of illness or disease on board, ships sometimes must anchor offshore or cruise around until they are cleared to enter their port of call.
Comparison of Speeds of Different Cruise Ships
On the other hand, let’s say you’re crossing a huge stretch of ocean on a Transatlantic cruise. For those long days at sea, the ship will likely sail at its maximum cruising speed to cover more miles faster. For bigger ships, the optimum cruising speed is Kn (23 mph / 37 kph).

The large ship carried enough fuel to last 12 days between ports. Usually, ships use fueling barges to fill their tanks or top up at their ports of call. Using lower-grade diesel, the powerful engines that power these boats are not as efficient as diesel used in cars and trucks.
At night, you’re not likely to see other ships or land, which can make the ship’s movement seem faster. Cruise ships don’t travel faster at night, but they might appear to because there are fewer distractions. The top speed is the maximum speed the ship can reach, but it’s rarely used because it consumes a lot of fuel. Many modern ships use gas turbines or diesel-electric engines to propel the boat and power shipboard systems. Larger ships may incorporate two power sources for propulsion and electrical power, respectively.
How fast can a cruise ship travel?
Royal Caribbean states that the average speed of their cruise ships is 18 to 20 knots. Ships aren't the fastest method of transportation, but that doesn't mean it's not fun to calculate your speed when you're sailing. Unlike land travel, ship speed is not measured in miles per hour. The Queen Mary 2 holds the title of fastest cruise ship in the world with speeds of 30 knots. This is a phenomenal speed considering the ship is close to 150,000 gross tons in size . This incredible speed allows Cunard to offer 7 day transatlantic cruises between Southampton and New York on Queen Mary 2.
A ship’s propulsion system, which can vary between traditional diesel-electric engines and gas turbines, can also influence its speed. You can learn more about how these propulsion systems work in our article about cruise ship stability. By gaining insights into these aspects, you’ll be better equipped to choose the right cruise for your preferences and make the most of your time at sea. A cruise ship can typically reach a speed of around 30 knots, about two to three knots higher than its cruising speed, but it’s not likely to go that fast. Cruise ships rarely hit top speed and will usually only do so if necessary. They typically don’t go at their top speed, unless they are behind schedule.
Cruise Lines And Ship Sizes: From Massive Ships To Smaller Ships
However, many modern cruise ships are designed to be more fuel-efficient, with advanced hull designs and propellers that help to reduce drag and improve speed. Ah, the Royal Caribbean, they’re not just royal by name, but also by speed. On average, the Royal Caribbean cruise ships go a comfortable pace of about knots. But remember, this can fluctuate based on factors like weather, ocean conditions, or if the captain’s late for his tea time.
Furthermore, advancements in maritime technology allow for real-time weather monitoring, enabling captains to adjust ship speed proactively according to the forecasted conditions. The average speed of a cruise ship typically ranges from 15 to 20 knots (17 to 23 miles per hour). This speed ensures a balance between passenger comfort, fuel efficiency, and timely arrival at destinations. Higher speeds could compromise the stability of the ship and lead to increased fuel consumption, while slower speeds could affect the itinerary.
For example, the size and type of the ship, the weather conditions, and the distance to the next port of call can all impact the speed. Passengers may also note that boats slow in shallow water such as that found close to harbors. This prevents the boat from unexpectedly running into objects at low tide or in shallow seas. In open water, ships often move much faster toward faraway destinations. There’s more room to maneuver in deep water far away from populated areas. Speed limits in certain areas protect marine life (you wouldn’t want to upset the dolphins, would you?) and help prevent accidents.
Ports typically charge by the hour so getting there early is costly. At the same time, cruise ships have a schedule they need to keep. Did you know cruise ships will purposely slow down when arriving in port? You will rarely arrive earlier than expected, and that is because cruise lines are charged docking fees based on the amount of time spent in each port. This is impressive considering the massive size of most cruise ships these days.
Hurricane season can also have an impact on cruise ship speed and travel itineraries. A cruise ship may need to speed up, slow down, or adjust its course to avoid severe weather. For this reason, cruise ships strive to find that sweet spot between a swift cruising speed and maximum fuel efficiency.
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. However, if a passenger has a medical emergency and needs to reach the nearest port, the captain may choose to take the cruise ship to top speed. So, if you’re interested in how cruise lines operate and what affects ship speed, keep reading.
It’s about harnessing the power of modern vessels and also ensuring smooth sailing with an emphasis on comfort and efficiency. To sum it up, the future of cruise ship speed is looking just as bright and promising as the neon dancefloor on the disco night of your cruise. If the wind is strong, then they might increase their speed slightly. There are no official records regarding how fast a cruise ship goes because it varies depending on factors like weather conditions, sea state, etc. Knots were originally used because they represented a unit of measurement based on time rather than distance.
