Though I'd imagine the larger and more modern ferries can take the weather better than the 6,000 gross tonners I grew up crossing the Channel on. I remember how much of a revelation the Prins Filip (now MV Calais Seaways) was compared to everything else sailing to Belgium at that time.
They do handle it a lot better but when the seas a playing up they all get thrown about. The Calais seaways is a bit top heavy and does move about a fair bit. One I do remember for that behaviour was the old Stenna Invicta, when that came in through the harbour entrance and started to make it's turn around, by jove did it lean over. It was quite tall and quite narrow so didn't have the tread in the water that something like the old Kent had.

But they had to shut the duty free on account of the broken glass...
That's twice the size of the Filp...
Lots of Dover / Ramsgate - Oostende crossings on those, mainly the Stephanie, sometimes the Clementine. The engineering principles are cool too.
