How can I prevent or treat seasickness on a yacht charter?
Most seasickness on a crewed charter is preventable: take motion-sickness medication or wear acupressure/anti-nausea wristbands before you feel unwell rather than after, stay on deck in fresh air and look at the horizon rather than reading below deck, and tell the captain if you're prone to it — a good crew will choose a smoother route and calmer anchorages accordingly.
Key facts
- Motion-sickness remedies work far better taken before symptoms start than after, so plan ahead for longer passages.
- Being on deck, in fresh air, looking at the horizon reduces symptoms far more than staying below deck.
- Motor yachts and catamarans generally offer a steadier ride than a sailing yacht, which heels underway.
- Telling your captain in advance lets them plan calmer routes and time longer passages around smoother sea states.
What actually helps prevent it
Over-the-counter or prescription motion-sickness medication, and acupressure or electronic anti-nausea wristbands, are far more effective taken before you feel unwell — ideally the night before or morning of a longer passage — than once symptoms have started. Ginger (tea, capsules or crystallised) is a mild, well-tolerated option many guests use alongside other remedies.
Simple habits make a real difference too: staying on deck in fresh air, keeping your eyes on the horizon rather than a book or phone screen, and eating something light rather than an empty stomach all reduce symptoms for most people.
How the yacht and itinerary affect it
Motor yachts, especially larger ones with stabilisers, and catamarans with their flatter, more stable motion, are generally more comfortable for anyone prone to seasickness than a sailing yacht, which heels under sail. This is worth mentioning to your broker when choosing a yacht type, not just when you're already aboard.
A good captain routes around the worst sea states where possible and can time longer open-water crossings for calmer parts of the day — but this only works if you've told them in advance that motion sickness is a concern for anyone in your group.
If you do start to feel unwell
Get into fresh air on deck immediately, focus on a fixed point on the horizon, and avoid going below deck or focusing on a screen until you feel better — this alone resolves mild symptoms for many people within 20–30 minutes.
Tell the crew — they see this often and can offer a specific remedy they've found effective, adjust your seating or activity, and, if needed, discuss with the captain whether a shorter or different route is possible.
Common questions
Is a catamaran really better than a motor yacht for seasickness?
Both tend to be steadier than a sailing yacht; a catamaran's twin-hull design generally gives the flattest motion of all three, which is why it's often specifically recommended for guests prone to seasickness.
Should I bring my own seasickness medication or ask the crew?
Bring what has worked for you before if you know it, but also mention any tendency to seasickness to the crew — many carry common remedies onboard and can advise based on what's worked well for previous guests.
