How is cruise ship speed measured, and how fast is a knot?

On the other hand, higher speeds at night, when most passengers are indoors or in their cabins, would have less impact on the overall experience. Therefore, cruise lines carefully manage ship speeds to ensure that passengers can make the most of their cruise ship travel. Route and itinerary planning are integral to determining cruise ship speeds.

Why Do Ships Measure Speed in Knots?

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. On sea days, cruise ships will often slow down during the day when in favorable weather conditions. Sometimes, your ports are relatively close to one another, so there is no need for a fast sailing speed. You might notice that the ship increases its speed after sunset once most guests have migrated indoors for the evening. Cruise ships travel relatively slowly, with an average speed of 18 to 22 knots (20 to 25 miles per hour).

What Is Normal Cruising Speed?

These engines provide substantial horsepower, allowing large ships to maintain impressive speeds despite their enormous weight. Sometimes speed is important, like when you’re running late for work or need to get to the store before it closes. Other times, such as when you’re on a cruise, speed is something you want to avoid, or at least, not think about. Luckily, for travelers who love to see the world by ship, a cruising vessel has to go slower than what we’re used to with cars or planes. Otherwise, a cruise ship would burn too much fuel and zip past gorgeous scenery. The engines supply the power to turn propeller shafts that move the boat by displacing water.

Some Notable Mentions for Fastest Cruise Ships

To learn more about what a knot is and how it relates to speed, check out our article explaining how fast a knot is. When sailing with favorable winds, they can sometimes get up to 10 knots. The Queen Mary II travels at 18 knots making it the second fastest cruise ship on Earth. With room for almost 2000 guests, there is plenty of space aboard the QM2 for everyone to enjoy themselves. There are three restaurants, six lounges, eight bars, nine swimming pools, and seven whirlpool spas.

Finally, if you’re concerned about motion sickness, it’s crucial to choose a cabin that minimizes the ship’s movement. Our guide to the best rooms on a cruise ship for motion sickness can help you make the right decision for a comfortable journey. To better understand the speeds of various cruise ship models, it’s helpful to know the meaning behind their prefixes. Our guide to ship prefix meanings provides an overview of the prefixes used for different types of vessels. If you’ve ever marveled at the sheer size and majesty of a cruise ship, you may have found yourself wondering just how fast these floating behemoths can go. In this article, we will dive into the fascinating world of cruise ship travel and explore the question of how fast these vessels can actually go.

Cruise ships typically travel at speeds of 21 to 24 knots, which is equivalent to 38.9 to 44.4 km/h. 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.

Speed and Onboard Experiences: The Interplay

The maximum speed for most modern vessels is about 30 knots or 34.5 mph, but just because they can glide along that fast doesn't mean they actually do, or at least not all the time. Here, I'll cover how cruise ship speed is measured, how to calculate your ship's speed in miles per hour and some considerations that could affect how fast you're going. But just because these cruise ships CAN travel that fast doesn’t mean they ever do.

Wooden ships didn’t have nearly the same maximum speeds as modern ships. A cruise ship needs to get to the next port on time, not early or late. While your car could easily leave a cruise ship in its wake on land, in the open ocean, it’s a whole different ball game. On average, cars can go about miles per hour, while cruise ships go around miles per hour.

How Cruise Ship Speed Affects Itinerary

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. Most ships sail at a comfortable cruising speed for the majority of one sailing. The speed of your cruise ship varies greatly depending on the ship’s size and engine power.

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.

Also, traveling at the fastest possible speed with all engines open would hurt efforts to conserve fuel and travel efficiently. Another reason cruise ships don’t go faster is to minimize motion and sea sickness and ensure passengers have a smooth journey. While they want passengers to feel like they’re on a cruise ship, it’s also nice to be so comfortable that they forget they’re on a cruise ship.

However, this is just an average and can vary depending on various factors. A modern cruise ship typically travels at a speed of about 20 knots (23 miles per hour) throughout the day and night. It’s important to note that there isn’t a significant difference in the speed of cruise ships during the day versus nighttime. Contrary to popular belief, cruise ships do not go faster at night. The maximum speed for most cruise ships is between knots per nautical mile, which is a maximum of 35 miles per land-based mile.

Before going any further, it’s crucial to understand how speed is measured on water. I’m Bobby Pham, but you can call me “Bobby on Cruise.” I’ve been cruising the high seas and exploring the world for years, and I’m thrilled to share my passion and expertise with you. When not cruising, I spend my time on growing my marketing agency. "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 takes roughly 6 days to complete the crossing of the Atlantic ocean.

Cruising is part of the experience — not just a means to get where you’re going. 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.
