[Complete Guide] For Those Worried About Cruise Ship Motion! Professional Know-How to Prevent Seasickness
When planning your first cruise trip, the biggest concern many people face is the "motion of the ship" or "seasickness."
However, modern cruise ships are equipped with advanced technology, and with proper preparation and knowledge, the impact of motion can be minimized.
In this article, we will thoroughly explain, based on objective facts, the know-how ranging from the mechanics of ship motion to pre-trip preparations like choosing a cabin, and immediate countermeasures for the day of the trip.
By reading this article, you will be able to resolve your anxiety about motion and enjoy a truly safe and comfortable cruise.
Why do cruise ships sway? Basic causes and mechanics of motion
Correctly understanding the causes of cruise ship motion is the first step toward developing effective countermeasures. First, we will explain in detail the environments where ships are prone to swaying and the excellent anti-sway features equipped on modern ships.

Characteristics of weather and sea areas where ships are prone to swaying
The motion of a ship is largely determined by wind strength, wave height, and the geographical characteristics of the sea area being navigated. In particular, in weather where typhoons or low-pressure systems are approaching, the sea becomes rough and large swells are likely to occur, causing the ship to sway in response.
In addition, routes that go into the open ocean, straits with strong currents, and areas where water depth changes rapidly tend to have relatively higher waves. In the waters near Japan, the Sea of Japan in winter, which is affected by seasonal winds, and the Pacific Ocean in summer, which is a path for typhoons, are known as sea areas where motion is easily felt.
The capabilities of the "anti-roll devices (stabilizers)" installed on the latest large passenger ships
Modern large cruise ships are equipped with cutting-edge technology to dramatically reduce motion. A prime example is the anti-roll device called a "stabilizer (fin stabilizer)" installed on the underwater part of the hull.
This is a wing-like device that protrudes from the side of the ship like a fish fin, and it operates as a computer instantly senses the tilt of the waves. The capability of this stabilizer is very high, and it is possible to automatically cancel out up to nearly 85% to 90% of the ship's roll.
Therefore, in normal, calm weather, passengers can spend their time so comfortably that they even forget they are moving.
[Before Boarding] Pre-trip measures to minimize cruise ship motion
To suppress motion during a cruise trip, the battle begins at the planning stage before boarding. We will introduce three highly effective pre-trip measures that you can practice when booking your trip or packing your luggage.
How to choose a "cabin" and its location to be less prone to seasickness
Options for "large passenger ships" and "routes" with less impact from motion

How to Choose and Position Your Cabin to Minimize Seasickness
On a ship, there are areas that are structurally the least prone to feeling motion and areas where motion is felt more intensely. If you want to minimize motion, the cabin you should choose is one located in the middle of the ship and on as low a deck as possible.
Because a ship moves like a pendulum, the center and lower decks, which are the pivot points, provide the most stable space with the least movement. Conversely, cabins at the bow (front), stern (rear), and on higher decks near the top of the ship tend to amplify the sensation of pitching and rolling.
When booking, be sure to check the deck plan carefully, as securing a position close to the ship's center of gravity is your best line of defense.
Choosing 'Large Cruise Ships' and 'Routes' with Less Motion
Since a ship's size is proportional to its stability, the golden rule for those worried about motion is to choose a large cruise ship with high gross tonnage. Generally, super-large cruise ships exceeding 100,000 tons are less affected by wave impact due to their overwhelming weight.
Also, when choosing a tour, it is important to check whether the route primarily passes through inland seas. For example, the Seto Inland Sea in Japan, the Mediterranean Sea, and the Caribbean Sea are surrounded by land, so they tend to have calm waves throughout the year.
If it is your first cruise, it is recommended to choose a large ship and start with a short cruise that travels through waters where motion is less likely.
Essential Seasickness Remedies to Prepare Before Boarding
To ensure you are fully prepared for your voyage, bring along seasickness remedies that work for you. The most reliable method is to bring a generous supply of over-the-counter seasickness medication that suits you from a pharmacy you are familiar with in Japan.
While you can obtain medicine on board international ships, the ingredients may be strong or not suit your body, so purchasing them in advance is recommended. In addition to medication, acupressure bands (Sea-Bands) that stimulate pressure points on the wrist to suppress nausea, as well as menthol-based peppermint oil, are also effective.
Simply having these items on hand provides peace of mind, knowing that 'everything will be fine even if something happens,' which helps prevent seasickness.
[On Board/Day of Departure] Immediate Measures to Try When You Feel Motion
No matter how well you prepare, the ship may start to sway due to sudden changes in weather. Here are specific tips on actions you can take immediately on board to prevent your condition from worsening.
On the timing for taking the 'correct seasickness medication' to prevent motion sickness
On the scenery to look at and how to spend your time on board when you feel motion
On precautions regarding food and alcohol to avoid worsening seasickness
The Timing for Taking the 'Correct Seasickness Medication' to Prevent Motion Sickness
To maximize the effectiveness of seasickness medication, the timing of when you take it is more important than anything else. The most effective time is before the ship starts to sway, or immediately after confirming the ship has departed.
The human brain has a characteristic where, once it experiences severe motion sickness, it becomes harder for medication to be effective if taken afterward. Therefore, check the schedule and weather forecast, and take proactive measures as soon as you know you are 'heading out into the open ocean' or that 'the waves look high tonight'.
Absorbing medication into your stomach before symptoms appear is a professional golden rule for spending your time comfortably on board.
Scenery to look at and how to spend your time on board when you feel the motion
If you feel the ship starting to rock significantly, first control the information entering through your vision to prevent brain confusion. Staying in your cabin and staring at a smartphone screen or a book is strictly prohibited, as it causes a discrepancy between your vision and your inner ear.
When you feel the motion, go out to the deck and fix your gaze on the distant, stationary horizon and try to be conscious of it. Also, while breathing in the fresh air, it is effective to move to the center of a public space where the ship moves the least.
To take your mind off the motion, listen to relaxing music or try closing your eyes lightly and repeating deep breaths.
Points to note regarding meals and alcohol to avoid worsening seasickness
How you eat on board and your choice of indulgences also significantly affect your resistance to motion through stimulation of the digestive tract. When the ship is rocking, avoid overeating and drinking, and adjust your intake to about 80% full with easily digestible foods.
Being too hungry can also cause stomach acid secretion and make you more prone to nausea, so it is ideal to nibble on crackers or similar items little by little. Also, alcohol disrupts the function of the inner ear and is the biggest cause of rapidly worsening seasickness symptoms.
Refrain from drinking alcohol during times when the motion bothers you, and choose drinks that settle your stomach, such as sparkling water or ginger ale.
What to do if you get seasick due to severe motion
No matter how many measures you take, you may still be struck by severe seasickness depending on your physical condition or the weather. Even if you feel completely unwell, knowing the following coping methods will help you stay calm and move toward recovery.
Utilizing the ship's medical center and consulting with a doctor
Postures and refreshment methods for spending time comfortably in your cabin
Utilizing the ship's medical center and consulting with a doctor
If you have strong nausea or dizziness that makes you feel it is difficult to recover on your own, do not push yourself and rely on the ship's medical facilities. All full-scale cruise ships are equipped with a medical center where doctors and nurses are stationed.
At the medical center, even for severe seasickness, it is possible to get fast-acting injections or powerful medical-grade anti-nausea medication prescribed. It is wiser to receive professional treatment and recover in a short time than to hesitate and continue suffering in your cabin thinking, "It's just seasickness."
Note that there is often a fee for using the medical center, so it is recommended to purchase appropriate overseas travel insurance in advance.
Postures and refreshment methods for spending time comfortably in your cabin
If you don't need to go to the medical center but want to lie down for a bit, add a little ingenuity to how you spend time in your cabin. When lying on the bed, try to sleep in an orientation where your head is aligned with the axis of the motion relative to the direction the ship is rocking (pitching or rolling).
Also, rather than lying completely flat on your back, a posture with your upper body slightly elevated using cushions will prevent acid reflux and be more comfortable. If the air in the cabin feels stuffy, it increases discomfort, so if you have a room with a balcony, open the door slightly to let in some cool fresh air.
Applying a cold towel to your forehead or the back of your neck to cool your blood vessels can help calm autonomic nervous system imbalances and alleviate nausea.
Frequently Asked Questions (Q&A) About Cruise Ship Motion Sickness Prevention
Q1. I am prone to seasickness, but can I still enjoy a cruise vacation?
A1. Yes, you absolutely can. Modern large ships have stabilizers that significantly reduce motion, and by choosing your cabin carefully in advance and taking medication at the right time, many guests enjoy comfortable trips without any issues.
Q2. Is there motion sickness medication available to be distributed or purchased on board?
A2. Many ships provide motion sickness medication for free or for a fee at Guest Services (the front desk) or the infirmary. However, since foreign-made medications may have stronger ingredients than what you are used to in Japan, it is best to bring your own familiar over-the-counter medication from Japan whenever possible.
Q3. What are the times and locations where cruise ship motion is most intense?
A3. In terms of timing, you are more likely to feel motion at night when the ship is sailing in the open ocean, away from the coast and without any obstructions. As for locations on the ship, the areas furthest from the center of gravity, such as near the top deck at the bow (front), are where the range of motion is greatest.
Summary
We have provided a comprehensive explanation of how to deal with cruise ship motion, covering everything from causes to advance preparation and actions to take on the day. By choosing a large cruise ship protected by modern technology and securing a cabin on a lower deck in the center of the ship, the risk of motion sickness is significantly reduced.
Furthermore, if you master taking medication a step ahead of the motion and learn the correct way to spend your time on board, there is no need to fear seasickness. Take thorough precautions to eliminate your anxiety and take the first step toward a wonderful luxury journey on the sea.
