Short answer
Most people do not get seasick on a river cruise. Rivers are generally calm, the ships are relatively small and slow, and the water is sheltered. A few people notice mild motion in specific circumstances, such as in locks, or after a day of travel that left them tired and unsettled, but significant seasickness is uncommon.
Why rivers are calmer than the sea
The sea produces swells that rock a ship in several directions. River ships don’t face this. They sail on enclosed waterways with little wave action, and many are flat-bottomed, which suits shallow rivers and canals. Passengers frequently say the ship feels more like a floating hotel than a vessel at sea.
How fast river cruise ships go
River cruise ships typically move at a relaxed pace. Estimates commonly put average cruising speeds at around 10 to 13 miles per hour (roughly 20 to 25 kilometres per hour), though this varies. Several things affect actual speed:
- Current. Sailing downstream is faster over the ground than sailing upstream.
- Locks and canals. Ships slow for locks, narrow channels, sharp bends and shallow sections.
- Local rules. Some stretches have speed limits.
- Time of day. Many ships sail while passengers sleep or are on excursions and stay docked when guests are touring.
By comparison, ocean-going cruise ships often cruise at around 20 knots or more. That speed difference is one reason river sailing feels so different. See river cruise vs ocean cruise for more.
When you might still feel motion
- Locks. Ships rise and fall in locks, and you can feel small movements and bumps.
- Wide or open stretches. Wind can create a little chop on large rivers or lakes on some itineraries.
- Wakes. Passing vessels can occasionally cause a brief rock.
- Starting and stopping. Docking and departing can produce subtle shifts.
- After disembarking. Some travellers feel a little unsteady on land, sometimes called “sea legs”, but usually only for a short time.
If you are prone to motion sickness
If you get queasy on boats, a river cruise is usually a safer bet than an ocean voyage. Some sensible steps:
- Talk to your doctor or pharmacist about suitable remedies, especially if you take other medication or are pregnant.
- Bring the remedies you have found helpful before, such as ginger, acupressure bands or over-the-counter products.
- Spend time on deck in fresh air and look at the shoreline or horizon.
- Eat a light breakfast rather than going out on an empty stomach.
- Avoid reading or looking at screens for long periods while the ship is moving.
Cabin choice
On ocean ships, cabin location matters because the bow and the upper decks move most. On river ships, the difference is much smaller, but a lower, mid-ship cabin will generally be the steadiest. A cabin away from the engines may also be quieter, which helps sleep.
Other things that feel like seasickness
If you feel unwell on a river cruise, motion is not always the cause. Heat, dehydration, rich meals, alcohol or jet lag can all make you feel off. Drink water, adjust your food and drink, and ask the crew for advice. If symptoms are severe or persistent, seek medical help.
