You are on vacation and do not want the ship to be moving so fast it becomes annoyingly noticeable! Those who are prone to motion sickness would not appreciate that. Usually, the diesel fuel that they use for locomotion is a lower grade than what goes into roadworthy diesel vehicles.
How Far Can A Cruise Ship Travel In A Day?
Picture the fastest cruise ship with a sleek figure like a runway model, if you will. It’s hard to imagine a massive vessel, complete with rooms, restaurants, entertainment centers and possibly hundreds, sometimes thousands of passengers, moving swiftly. But, if you’ve ever set sail before, you know large ships make it from port to port somehow without sprinting across the water. In this guide, we’ll answer some speed-related questions and explore factors that impact a ship’s cruising rate. As an example, let’s say you’re cruising from Miami overnight to a private island in the Bahamas.
Cruise Line Top Speeds
It’s essential to consider your preferences, travel goals, and desired level of relaxation when choosing a slow-speed cruise ship. Another factor that affects cruise ship speed is fuel consumption. The amount of fuel a ship carries can determine how fast it can go and for how long. A heavier ship will require more fuel to maintain speed, while a lighter ship can go faster with less fuel. This is impressive considering the massive size of most cruise ships these days. Captains will also adjust the cruise ship speed for passengers to enjoy a specific landmark or scenery.

If you’re sailing under the northern lights, for example, you probably don’t want your ship to zoom ahead while you’re still scrambling for your camera. Nor would you want to buzz through Norwegian fjords without getting to take in the scenery. A cruise is about enjoying the voyage and the natural beauty surrounding you just as much as the destination.

Cruise Ship Cruising Speed
The ship includes 12 dining venues, 11 bars, 16 lounges, and 13 swimming pools. Onboard entertainment options include live shows, karaoke, dancing, and casino games. However, some vessels from popular cruise lines, such as Carnival and Royal Caribbean, are known to go over 25 knots from time to time.
What’s a Knot Anyway?
In the real world, however, ships are at the mercy of Mother Nature. By the 17th century, the practice evolved to include a length of rope with knots tied at regular intervals. Sailors would toss the rope into the water and count the number of knots that drifted past the ship’s stern in a given amount of time. The last ship in the fleet to hold the unofficial award, which dates back to the 1800s, was Queen Mary, which is currently a floating hotel in Long Beach, California, near Los Angeles. But fast speeds are still needed in the case of an onboard emergency, or to outrun bad weather. The secret in managing speed versus fuel efficiency is in the ship's engineering.
These ships, while known for their entertainment offerings and sheer size. A passenger onboard may have a medical emergency and need transportation to the nearest hospital. Or perhaps another ship in the area sends out a distress signal and your cruise ship is the closest vessel that can help. 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.
If the distance between two ports is too great, the ship will spend a day at sea. The fastest ocean liner ever built was the SS United States which, on her maiden voyage in 1952, shattered the trans-Atlantic speed record and reached a top speed of 39 knots (45 mph). Cruise ships do sometimes go faster than the standard speed, such as when there is bad weather that they must quickly move away from. If another ship puts out a distress call, then a cruise ship may also speed up to offer assistance as soon as possible. A nautical mile is 6,076 feet, which is about 15% more than a mile on dry land (which is called a statute mile). But when asking how fast does a cruise ship go, that’ll depend on how far it needs to travel.
Factors Affecting Cruise Ship Speed
Before going any further, it’s crucial to understand how speed is measured on water. Cruise lines measure the speed of their ships using GPS systems. A GPS receiver measures the position of the ship every few seconds.
As a result, cruise ships don’t need to expend as much energy moving through water. At night, cruise ships also reduce their speed to avoid hitting other vessels. However, once you get into international waters, then you might want to consider making 15 knots since you could potentially cover thousands of nautical miles each week.
Most cruise ships maintain a speed of 21 to 24 knots to avoid aerodynamic drag that could eat up the ship’s fuel supply. Running out of gas in the middle of the ocean is obviously not an option. The QE2 used 380 tons of fuel every day to achieve 29 knots per hour. 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.
You can learn more about how these propulsion systems work in our article about cruise ship stability. Built in 1995, MV Oriana was the first new ship commissioned for P&O Cruises. This vessel hit 26.2 knots in sea trials and is considered the 3rd fastest cruise ship in the world.
Unlike highway traffic, ships generally have no specific speed limits. Several factors affect the speed of a cruise ship, including the itinerary, weather, and distance to the shore. The main exception is that a ship will speed up in the event of a storm or rough waters in hopes of passing through it quickly. The captain may sometimes decide to speed up if they know a storm is coming in hopes of outrunning it. Finally, a cruise ship maintains a certain speed to keep on schedule.
On the other hand, a headwind pushing against the bow or front of the boat can significantly slow it down, requiring more energy to travel at the same speed. Wind shear from wind hitting the boat from either side creates drag and makes it harder for the boat to move forward, consuming more fuel than a calm sea or one with a lucky tailwind. The speed at which cruise ships travel is a significant aspect of the overall cruising experience.
Just like when you drive your car on the motorway, if you drive at 80 mph, you’ll burn much more fuel during the journey than you would if you stuck to a steady 60 mph. With something as large as a cruise ship, that extra fuel will be expensive. To convert a speed in knots to miles per hour, you can multiply the knots by 1.151.
