Typical cruise ship speed is 20 to 24 miles per hour

Most cruise ships travel at a cruising speed of 20 to 24 miles per hour when moving between ports. This is the speed you'll experience during the bulk of your voyage—the steady pace that gets the ship from one destination to the next. The exact speed depends on the ship's size, engine power, and ocean conditions, but 21 to 22 mph is the most common range for modern cruise lines.

This speed is much slower than you might expect from a ship that weighs 100,000 tons or more. The reason is fuel efficiency. Cruise ships burn thousands of gallons of fuel per day, and speed has an enormous effect on consumption. Slowing down from 24 mph to 20 mph can cut fuel use by 20 percent or more. Since fuel is one of the largest operating costs for a cruise line, ships are designed to travel at the speed that balances getting passengers to their destination on schedule with keeping fuel costs manageable.

Key Takeaways

  • Cruise ships typically cruise at 20 to 24 miles per hour, with 21 to 22 mph being the most common speed.
  • Larger, newer ships often travel slightly faster than older or smaller vessels, but the difference is usually only 2 to 3 mph.
  • Ships can go faster in short bursts—up to 30 mph or slightly higher—but do not maintain that speed because fuel consumption becomes prohibitively expensive.
  • Ocean conditions, weather, and port schedules can cause a ship to slow down or speed up during a voyage.
  • The speed you experience as a passenger is the same whether you are on a small ship or a megaship; what changes is the distance the ship can cover in a day.

Why cruise ships don't go as fast as you'd think

A cruise ship's engine is powerful enough to push the vessel much faster than 24 mph. Most modern cruise ships can reach speeds of 28 to 32 miles per hour if they run at full throttle. However, cruise lines almost never operate at maximum speed because the fuel cost becomes astronomical. Fuel consumption increases dramatically with speed—roughly doubling when you go from 20 mph to 30 mph.

Think of it like driving a car. You can drive 80 mph on the highway, but doing so burns significantly more gas than driving 55 mph. For a cruise ship carrying 3,000 to 5,000 passengers across the ocean for a week, that difference translates to tens of thousands of dollars in extra fuel cost. Cruise lines have calculated that the optimal speed—the one that minimizes total operating cost while still keeping to a published schedule—is usually between 20 and 24 mph.

How ship size and age affect speed

Larger, newer cruise ships tend to travel slightly faster than smaller or older ones, but the difference is modest. A brand-new megaship from Royal Caribbean or Carnival might cruise at 23 to 24 mph, while a smaller ship or one built 15 years ago might cruise at 20 to 22 mph. The difference comes down to engine efficiency and hull design. Newer ships have more efficient engines and hulls that move through water with less resistance, so they can maintain a higher speed without burning proportionally more fuel.

However, this does not mean you will feel the voyage go faster on a newer ship. The speed difference is only 2 to 3 mph—barely noticeable to a passenger. What does change is how far the ship travels in a day. A ship cruising at 24 mph covers about 576 miles in 24 hours, while one cruising at 20 mph covers about 480 miles. Over a week-long voyage, that adds up to a difference of roughly 670 miles, which is why some itineraries require a faster ship.

Speed changes during your voyage

The speed listed in cruise line marketing materials is the average cruising speed, not the speed the ship maintains every single hour. Ships slow down when entering or leaving port, when navigating narrow channels or shallow water, and when encountering rough seas or storms. A ship might cruise at 22 mph in open ocean but drop to 8 to 10 mph when maneuvering into a port or passing through a strait.

Weather also affects speed. In heavy seas, a captain may reduce speed to improve passenger comfort and reduce stress on the ship's structure. Conversely, if a ship falls behind schedule due to weather delays, the captain might increase speed slightly to make up time—though this is done cautiously because the fuel cost of speeding up is substantial. Most cruise lines build a small buffer into their schedules to account for these variations.

How cruise ship speed compares to other vessels

Cruise ships are much slower than cargo ships or container ships, which often travel at 20 to 25 mph as well—so they are actually comparable. The real difference is that cargo ships are optimized purely for speed and efficiency, while cruise ships must balance speed with passenger comfort, entertainment, and amenities. A naval destroyer or military vessel can exceed 30 mph, and a speedboat can reach 50 mph or more, but those vessels are designed for very different purposes.

Ferries vary widely depending on their route and design. A short-distance ferry might cruise at 15 to 20 mph, while a high-speed ferry designed for longer routes can reach 35 to 40 mph. However, high-speed ferries burn fuel at a much higher rate and are typically used only on routes where the extra speed justifies the cost.

What determines the speed of your specific cruise

The itinerary and schedule determine how fast your ship will travel. A cruise line publishes a schedule that says the ship will arrive at each port at a specific time. The ship's speed is set to meet that schedule while minimizing fuel cost. If a cruise visits ports that are far apart, the ship will cruise faster to cover the distance. If ports are close together, the ship will cruise slower because there is less distance to cover and fuel savings matter more.

The time of year also plays a role. During hurricane season in the Atlantic and Caribbean, ships may take longer routes or adjust speed to avoid storms. In winter, when seas in northern regions are rougher, ships may slow down for passenger comfort. Cruise lines also adjust speed based on fuel prices—when fuel is expensive, ships cruise slightly slower to save money; when fuel is cheaper, they may cruise slightly faster to maintain schedules.

Frequently Asked Questions

Can you feel the ship moving at 20 mph?

Not usually. Once the ship reaches cruising speed in open ocean, the motion is smooth and steady. You will not feel the ship accelerating or decelerating unless the captain makes a significant change in speed, such as when approaching a port or encountering rough seas. The ship's size and weight mean that even at 24 mph, the acceleration is gradual and gentle.

Why do some cruises take longer than others if ships go the same speed?

The distance between ports varies. A cruise visiting nearby Caribbean islands might cover 400 miles per day, while a cruise visiting ports farther apart might cover 500 miles per day. The ship's speed is similar, but the route is longer or shorter. Additionally, some itineraries include more sea days (days spent traveling) than others, which adds time to the total voyage.

Do ships ever go faster to make up for delays?

Yes, but only slightly and only when necessary. If a ship falls behind schedule due to weather or port delays, the captain may increase speed by 2 to 4 mph to make up time. However, this is done sparingly because the fuel cost is high. Most cruise lines build buffer time into schedules to avoid needing to speed up.

Is 20 mph fast enough to cause seasickness?

Speed alone does not cause seasickness—wave height and motion do. A ship traveling at 24 mph in calm seas will feel smoother than a ship traveling at 15 mph in rough seas. Modern cruise ships are also designed to minimize motion, with stabilizers that reduce side-to-side rocking. Seasickness is more about the ocean conditions than the ship's speed.

How long does it take a cruise ship to stop?

A cruise ship traveling at 20 mph cannot stop quickly. It takes several miles and 15 to 30 minutes to come to a complete stop, depending on the ship's size and sea conditions. This is why cruise ships maintain constant speed in open ocean—stopping and starting would waste enormous amounts of fuel and time. Captains plan their routes and speed well in advance to avoid sudden stops.
