Which is the best ferry to use if you get seasickness?

I have read either here or on Tripadvisor that the Fred Olsen ferry is fast but bumpy?
The suggestion was, if any fear of sea sickness, the other ferry is slower but better? Is it also true that we can just buy tickets the day of, no need to reserve? The times on Fred Olsen are 2hrs and the other, 4hrs? Is it acceptable to have suitcases? Just checking.

This really does depend on the sea conditions but, generally speaking, the single-hull Armas is more stable than FOExpress (~2.5 hours) which is a catamaran.

Yep, you can buy tickets on the day but the stretch of sea between Tenerife and La Gomera is nearly always much calmer than that between La Gomera and La Palma. You can also travel with suitcases.

Thanks! The Armas is 4 hours? Gomera then La Palma?

It's between 3.5 and 4 hours depending on the departure time. All the crossings pass via La Gomera.

Thank you for the info.

Go on the slower boat, sit outside, and look forwards and you will be fine. Inside its alot easier to feel seasick. The fresh air outside also helps keep you feeling normal. Looking at the horizon also helps alot.
