If you suffer from motion sickness, we suggest that you avoid traveling by small high-speed ferries and that you opt for an open-deck conventional ferry instead. This could make your journey more comfortable, as fresh air usually helps relieve seasickness symptoms. Moreover, large ferries generally provide a smoother ride in windy conditions. If it’s not windy, then one of the larger high-speed boats might also be a good option. However, it’s probably safer to choose an open-deck conventional ferry when possible, as it’s hard to predict what the weather will be like on the day of your trip.
