Why the Ancona to Igoumenitsa crossing gets rough
Length is the story. The route passes from the central Adriatic through the deep southern basin and out past Corfu, so a bora event, a sirocco blow or an autumn low anywhere along the sea has a fair chance of intersecting your night. The ships are among the largest on the Adriatic, built for year-round trade, and most crossings most of the year pass with nothing worse than a gentle roll.

The physics is the same everywhere: see the catamaran guide. If the rocking follows you ashore afterwards, that is land sickness, which is normal, and it passes.
Frequently asked questions
Is the Ancona to Igoumenitsa ferry rough?
Over 17-odd hours the route crosses the whole Adriatic, so it can meet bora gusts in the north or sirocco swell in the south; in the settled May to September season most crossings are gentle end to end. The ferries are large, and the final Greek approach is protected by Corfu.
How long is the crossing?
About 16.5 hours with Superfast Ferries or Anek and up to 21.5 hours with Grimaldi Lines, typically departing in the afternoon or evening and arriving the next morning or midday, with camping on board offered in summer.
When is this corridor calmest?
May to September. Winter crossings run reliably but meet the Adriatic's named winds most often, and the long southern basin leg is where a sirocco will be felt. The route's length means checking the whole sea's forecast, not one port's.
What about seasickness medicine for a 17 hour ferry?
Ask a pharmacist or doctor before travel day; most motion sickness medicines are labelled for use before departure, and on a crossing with an overnight leg their drowsiness guidance is worth understanding. A midship cabin does the structural half of the job.
