Hmmm...This looks cool, but I'm not sure that it has enough wing area to be an effective ekranoplan. It doesn't seem to have much more wing area than the "Caspian Sea Monster", and that never really succeeded as an ekranoplan. But this is definitely a cool-looking design.
"Caspian Sea Monster" (realy called KM - "Корабль макет" - "A ship-mockup" in literal translation) has a very good performance, among other things. Ekranoplanes require a much smaller wing area, compared with the aircraft.
