Worried about feeling sick? The good news: the crossing is only 90 minutes, the ferries are large and stable, and the Channel is usually calm. Here's how to avoid seasickness anyway.
For most travellers, no. The crossing lasts just 90 minutes and the modern ferries are big, stable ships with stabilisers. On the majority of days the Channel is calm and you'll barely feel the motion. Only in strong winds (force 7+) can it get bumpy, and in severe storms sailings may be delayed or cancelled for safety – see our storm crossing guide.
Because the crossing is so short, even if you are prone to motion sickness, any discomfort doesn't last long – you'll see the white cliffs of Dover within an hour.
If you regularly suffer from severe motion sickness or take other medication, ask a pharmacist or doctor which remedy is right for you.
Children can be more sensitive to motion. The same tips apply: fresh air, a window or deck view of the horizon, light snacks and no screens. Bring a change of clothes just in case, and ask a pharmacist about child-suitable remedies before you travel. On the short Calais–Dover crossing, distraction – the open deck, watching the ships and gulls – usually does the trick.
