Will I Get Seasick on a Catamaran? Risk Calculator
It is the question that keeps people off the water — and usually for no reason. A big catamaran sits on two hulls, so it rolls far less than the small boats most people picture. Answer six quick questions and get your personal motion-sickness risk, plus the few things that make almost all the difference.
Feeling reassured? Pick your day on the water
Most guests never give seasickness a second thought once they are on board. Choose a calm morning cruise or an easy sunset sail and let the crew take care of the rest.
Seasickness on a large catamaran is uncommon. The twin hulls stay remarkably level, Crete’s mornings are usually calm, and the simplest steps — fresh air on deck, eyes on the horizon, and a tablet an hour before if you are prone to it — prevent it for almost everyone.
The honest truth about seasickness on a catamaran
Most people who worry about seasickness are picturing a small monohull yacht heeling over in the swell. A cruising catamaran is a different animal: two widely spaced hulls give it a broad, stable platform that resists the rolling motion that actually triggers nausea. That is exactly why catamarans are the boat of choice for day trips.
Add to that the conditions in Crete — sheltered bays, warm summer mornings before the afternoon breeze builds, and short, coast-hugging routes — and the great majority of guests feel nothing at all. The handful who are genuinely prone to motion sickness can almost always head it off with one simple precaution.
If you do start to feel it. Get up on deck into the fresh air, fix your eyes on the horizon or the coastline, and breathe slowly. Avoid reading or looking at your phone. Sip water, nibble a plain biscuit, and tell the crew — they help guests with this every week and carry remedies on board.
How this works. The calculator adds up the things that drive motion sickness — how prone you are, the route and sea state, where you sit, what you do on board and whether you take a precaution — and weighs them against the natural stability of a catamaran.

Seasickness on a catamaran — common questions
Do catamarans make you seasick?
Rarely. A cruising catamaran sits on two widely spaced hulls, giving it a broad, stable platform that rolls far less than a single-hull boat. Combined with Crete’s calm summer mornings and sheltered routes, most guests feel nothing at all. People who are prone to motion sickness can usually prevent it with a tablet taken about an hour before boarding.
How can I avoid getting seasick on a boat trip?
Take a motion-sickness tablet about an hour before you board if you are prone to it, stay on deck in the fresh air, keep your eyes on the horizon, and avoid reading or scrolling your phone. Eat a light meal beforehand, go easy on alcohol, and stay hydrated. These few steps prevent it for almost everyone.
Are catamarans more stable than monohull boats?
Yes. The two hulls of a catamaran are set wide apart, which resists the side-to-side rolling that triggers nausea. That stability is the main reason catamarans are used for day cruises and why they feel so much calmer than a small monohull yacht in the same conditions.
When should I take seasickness tablets?
Most over-the-counter motion-sickness tablets work best taken about an hour before you board, so they are active before any motion starts — taking them once you already feel unwell is far less effective. Always follow the instructions on the packet, and check with a pharmacist if you take other medication.
Do natural remedies like ginger work?
They can help with mild cases. Ginger (as sweets, capsules or tea) and acupressure wristbands work for some people and have no real downside, so they are a sensible backup. For anyone genuinely prone to motion sickness, a proper tablet is more reliable.
Is the morning or the sunset cruise calmer?
Mornings are usually the calmest, because the wind and waves in Crete tend to build through the afternoon. Sunset cruises are typically short and stay close to shore, so they are gentle too. If you are worried about motion, a calm morning departure on a sheltered route is the easiest choice.
What should I do if I start to feel seasick on board?
Move up onto the deck into the fresh air, fix your gaze on the horizon, and breathe slowly. Stop reading or looking at screens, sip some water and nibble a dry biscuit. Tell a crew member — they deal with this regularly and carry remedies on board, and it usually passes quickly once you are settled in the air with the horizon in view.
