The best cabin location if you get seasick

Where is the best cabin on a cruise ship for seasickness?

The best cabin for seasickness is on a lower passenger deck, in the middle of the ship. Ships move around a central point, and the closer you are to it, the less motion you feel. A midship cabin a few decks above the waterline will feel noticeably steadier in a swell than one at the very front of the ship or high up near the pool deck.

If you can afford it, add a window or balcony. Being able to see the horizon helps many people feel better, and a balcony lets you step outside for fresh air without walking through the ship. If budget is tight, though, a low midship interior beats a high forward balcony for motion.

Why midship and low decks move the least

A ship at sea moves in two main ways. Pitching is the bow rising and falling as the ship rides over waves, like a seesaw from front to back. Rolling is the side-to-side sway when swells hit from the side. Both are felt most at the far ends and the top of the ship, and least near its center.

Think of a seesaw: someone sitting at the pivot barely moves, while the person on the end swings up and down. On a ship, the pivot is roughly midway along its length and fairly low down. Cabins near there get the smallest movement in both directions.

Height exaggerates roll in particular. The same few degrees of sway that feel like gentle rocking on deck 4 can feel like a slow lurch on deck 12, simply because you're farther from the pivot.

Forward, aft or midship: which part of the ship is best?

Midship is best, aft is a reasonable second choice, and forward is the one to avoid if you're prone to motion sickness. Forward cabins sit at the end of the seesaw that rises and falls most as the bow meets oncoming waves.

Aft cabins are a matter of personal tolerance. The stern also pitches, but some cruisers find the motion there smoother than at the bow, and aft-facing balconies are much loved for their wake views. Low aft cabins can also pick up vibration from the propellers, especially when the ship maneuvers in and out of port, which bothers some light sleepers.

• Midship, low to middle deck: the steadiest option on any ship.
• Aft, low to middle deck: more pitching than midship, but often acceptable; some vibration.
• Forward, any deck: the most pitching in a head sea; best avoided.
• Any position on a very high deck: more roll, plus noise from pool decks or sports courts above on some ships.

Interior, oceanview or balcony if you get seasick?

Location matters more than cabin type, but a view helps. Motion sickness comes from a mismatch between what your inner ear feels and what your eyes see. In a windowless interior, your eyes report a still room while your body senses movement, which is exactly the mismatch that triggers queasiness for many people.

An oceanview window or balcony door lets you fix your eyes on the horizon, which steadies many people. A balcony adds fresh air, which plenty of cruisers find more helpful than anything else when they feel unwell.

If you book an interior, choose one low and midship, and spend rough stretches in a public area with big windows on a low deck, such as a midship lounge or the main atrium's lower levels. Many ships also stream a bow-camera view to the cabin TV, which some people find helps.

Does ship size matter for seasickness?

Yes. In general, bigger ships feel more stable in moderate seas because their size and weight soften the effect of each wave. A 3,000-plus-passenger mainstream ship from Royal Caribbean, Norwegian, Carnival or MSC will usually ride a typical Caribbean swell with little noticeable movement.

All modern cruise ships use stabilizers, fins that extend from the hull to dampen rolling. They work well against side-to-side motion but do much less for pitching, so cabin position still matters on even the largest ships.

Small ships are a different story. Expedition ships, sailing ships and small luxury ships can move noticeably more in open water. If you're drawn to one of these but are motion-sensitive, pay extra attention to the route and plan ahead with your doctor.

Pick a calmer itinerary, too

The route can matter more than any cabin. Some waters are known for being calmer, and some are notorious for big swells. If you're seasick-prone, choose sheltered routes, and ideally avoid long open-water crossings for your first cruise.

• Usually calmer: the Caribbean and Bahamas outside storm season, Alaska's sheltered Inside Passage, the Mediterranean in summer, and river cruises, which have almost no motion.
• Often rougher: the Drake Passage on the way to Antarctica, the North Atlantic on transatlantic crossings, the Bay of Biscay, the North Sea and the Tasman Sea between Australia and New Zealand.
• Watch for open stretches on otherwise calm routes, such as Queen Charlotte Sound between Vancouver and the Inside Passage, or the Gulf of Alaska on one-way sailings to Seward or Whittier.
• Hurricane season in the Atlantic runs June 1 to November 30, peaking in roughly August to October; ships reroute around storms, but sea days near a system can be bumpy.

How to book a seasickness-friendly cabin

Start by opening the deck plan for your ship on the cruise line's website. Find the elevator and stair towers in the middle of the ship and look for cabins close to them on the lowest decks with passenger cabins. Those are your targets.

Book early. Midship cabins on lower decks are popular with seasoned cruisers, and the best of them go first. Choosing a specific cabin number, rather than a guarantee fare, is the only way to be sure of the location.

• Avoid guarantee fares: the line assigns the cabin and it could be far forward or high up.
• Check above and below your chosen cabin so a steady location doesn't come with nightclub or pool-deck noise.
• Families who need two rooms should look for adjacent or connecting cabins midship and book well ahead.
• If you have a choice between a high midship balcony and a low midship oceanview, the lower cabin will feel steadier.

What else helps once you're on board

Even the perfect cabin won't make every sea day feel like solid ground, so combine it with simple habits. Get outside on a low, open deck and look at the horizon, eat light meals, sip water, and go easy on alcohol in the first day or two. Lying down with your eyes closed in a dark cabin can also help in rough weather.

Medication, patches and other remedies are personal decisions. Talk to your doctor or pharmacist before you travel about what's suitable for you and when to start it. On board, the ship's medical center can help if you feel very unwell, usually for a fee.
