South Atlantic expedition cruises can encounter significant swell, and no route, month or ship can guarantee calm water. If you are prone to motion sickness, plan before departure rather than waiting for rough conditions to start.
Ship and cabin considerations
Motion varies with sea state, vessel design, speed and heading. A lower, more central cabin is commonly preferred by motion-sensitive travelers, but it does not remove movement.
Practical habits at sea
- Keep hydration and simple food intake steady if tolerated.
- Use handrails and avoid unnecessary movement in rough conditions.
- Looking toward the horizon can help some travelers.
- Keep essential medication accessible rather than inside checked luggage.
- Follow the ship doctor or medical team’s instructions.
Medication planning
Motion-sickness medicines and patches have different contraindications and side effects. Discuss suitable options with a qualified clinician or pharmacist before the voyage, especially if you take other medication or have relevant medical conditions.

Prepare before you feel sick
Motion-sickness measures tend to be more useful when planned before rough conditions rather than after severe symptoms begin. Ask a clinician or pharmacist what is appropriate for you, especially if you take other medication. On board, eat lightly, hydrate, get fresh air when safe and look toward the horizon. Follow crew restrictions if outside decks close in heavy weather.
