I have taken a several hour hydrofoil ride in the Mediterranean in moderate swells.
The ride is deeply nauseating as the foils are positioned towards the outside corners and (on this 200+ passenger craft) catch the swells independently. The result a ride with similar pitch and roll as a traditionally-hulled ferry, with far more yaw and far less periodicity.
