I foil and efoil as a hobby; Once on foil, surface waves have no impact as long as you keep the foils in the water -- this means observing and adjusting attitude. If you do it well, you can maintain full speed and only feel the attitude changes (no bumps). Though, if it is very windy and wavy on the ocean/lake it is more difficult to develop foiling speed to take off. The reason why Candela is pioneering sub surface foils now is because it takes a reasonable amount of sensors and computation to avoid the foil breaching. For the most part, you wouldn't want to take a sub surface foiling vessel flying out in a storm with significant swells, but that's not what most boating is anyway.
