What helps on this crossing
- Sit midship on a low deck. Salerno to Positano takes about an hour, so that is the leg to prepare for.
- Keep your eyes on the horizon and put your phone away for that leg. Looking at a screen holds your eyes on something that is not moving while the boat is.
- Check the forecast the day before and ask at the pier ticket office about your departure. Travelmar says it can cancel or change any scheduled trip.

For what the trials actually say about the oldest trick on that list, see the verdict on looking at the horizon. If the rocking follows you ashore afterwards, that is land sickness, which is normal, and it passes.
