How to Avoid Seasickness on a Sailing Holiday

Fear of being sick is the single biggest reason people talk themselves out of a sailing holiday — and it's largely misplaced. Most seasickness is mild, preventable, and gone within a day or two as your body adapts. Even those who feel rotten in the back of a car can have a blissful week afloat, provided they take a few simple precautions and pick the right water. Here's how to stack the odds firmly in your favour.

The short answer

Seasickness happens when your inner ear feels motion your eyes can't see. You beat it by preventing it, not curing it: take medication before you sail, stay on deck watching the horizon, sit low and central where the boat moves least, eat lightly, and keep well hydrated. Choose sheltered cruising grounds and a stable catamaran if you're anxious, and the problem usually never arrives.

Why it happens

Motion sickness is a sensory conflict. Your inner ear registers the boat's roll and pitch, but if your eyes are fixed on something still — a phone, a book, a cabin wall — your brain gets contradictory signals and responds with nausea. That's why reading below deck is the fastest route to feeling awful, and why staring at the horizon is the fastest route to feeling fine. Understanding this one mechanism tells you almost everything about prevention: keep your eyes and inner ear agreeing with each other.

The good news is that almost everyone adapts. This is "getting your sea legs," and it usually takes a day or two. After that, your brain recalibrates and the motion simply stops registering as a threat.

Prevention that actually works

Prevention beats treatment every time — once you feel unwell, medication struggles to catch up. Take these steps from the outset:

• Medicate early. Over-the-counter tablets like cinnarizine (Stugeron) or hyoscine (Kwells) work best taken an hour or two before you leave the dock, then topped up as directed. Scopolamine patches, from your pharmacist or GP, last around three days and suit longer passages.
• Try ginger. Ginger — capsules, chews, ginger biscuits or real ginger tea — has genuine evidence behind it and no drowsiness. It's an excellent backstop alongside or instead of tablets.
• Consider acupressure bands. The elasticated wristbands that press the P6 point help some people; they're cheap, harmless and worth packing.
• Eat and drink sensibly. Go afloat with a light, bland meal inside you — never an empty stomach and never a heavy fry-up. Sip water often; dehydration makes everything worse. Skip excess alcohol the night before.

What to do onboard

Where you put yourself on the boat matters enormously. If you feel the first flutter of queasiness, act immediately rather than hoping it passes.

• Get on deck. Fresh air and an open view are the best medicine. Below decks is the worst place to be.
• Watch the horizon. Fix your gaze on the distant, stable land or sea line. Give your eyes the motion your inner ear already feels.
• Sit low and central. The middle of the boat, near the waterline, moves least. The bow and the stern pitch most.
• Take the helm. Anticipating the boat's movement — as the helmsman does — dramatically reduces nausea. This is why the skipper is almost never sick.
• Stop staring at screens. No phones, no reading, no chart-plotting below until you've adapted.

Choosing calmer conditions

You can design a lot of the risk out before you even book. The right destination and boat make seasickness a non-issue for most crews.

• Pick sheltered waters. Enclosed, island-studded cruising grounds mean short hops and flat water. The Greek Ionian and the sheltered Dalmatian channels of Croatia are famously gentle, with calm mornings and reliable, moderate afternoon breezes.
• Favour a catamaran. A catamaran sits on two hulls and stays markedly flatter than a monohull — it rolls far less, both under way and at anchor. For nervous crews it's the single best choice.
• Sail in the settled season. Peak summer generally brings steadier, more predictable weather than the shoulder months.
• Sail early, rest in the afternoon. Many grounds are glassy at dawn and breezier by mid-afternoon; plan longer passages for the calm of the morning.

When you browse the fleet, filter for a catamaran in a sheltered ground and you've solved most of the problem before you've packed a bag.

Frequently asked questions

Will I definitely get seasick? Probably not. Most people feel fine, and those who do feel queasy usually adapt within a day. Prevention and calm-water destinations make it a rarity.

Do catamarans really help? Yes. Two hulls give far less roll than a single-hulled yacht, both sailing and at anchor. They're the top pick for anyone prone to motion sickness.

What's the best medication? Cinnarizine and hyoscine are the common effective tablets; scopolamine patches suit longer trips. Take any of them before symptoms start. Ginger is a strong, drowsiness-free alternative.

Can I be sick the whole week? It's very unusual. Nearly everyone gets their sea legs within a day or two, after which the motion simply stops bothering them.

Nervous about the motion? Stack the deck in your favour — browse catamarans for the steadiest ride, or pick the gentle, sheltered bays of the Greek Ionian for your calmest possible first week.
