Looking through the links, I kind of like the appearance of the Bartini Beriev VVA-14 without the wings. I looks like some kind of futuristic Marine landing craft....
I didn't realize that the ekranoplans got that large! 500 tons is a lot of mass to be hauling through the sky 20 ft off the ground.

ecg, the link here proposes that they would be able to operate at Sea State 7 and that's not exactly calm water and 1100 ton craft to boot! I understand they work better under calm water, but that doesn't mean they can't work out in the open ocean.

I see your point about more robust construction, but wouldn't that be mitigated by using composites, and ti alloys to lighten the load? Assume you have several billion dollars to allocate to r&d; what would be the maximum practical size that a hydrofoil boat could be made? There are lots of deep draft ships that never go to port like the big cruise liners, so I don't really see that as an issue in my mind.
