Here is a video clip that shows a small conard style ekranoplan some what like the design I currently have for a non flying sub.

The wing profile I was planing on having for a none flying trimaran sub, has no real lift since it's the the same shape on the top as it is on the bottom. This is so when your underwater your not fighting the subs wings to go down, creating more drag which in turn uses more power when neutrally buoyant. So if I want this style of sub to fly like a ekranoplan, then I'll need to finish a design for changing the shape of the bottom panel of the wing so it's flat like a planes wings. This said panel would be a strong flexible material like Kevlar with hydraulics turning a number of cams that push on long bars that in turn are in contact with the Kevlar panel warping it near the leading edge of the wing for under water mode. The edges of the Kevlar panel are over lapped with and protected my another composite and strong springs keep the panel tight so went the cams are turned back, the bottom of the wing is flat again for surface flight mode. There is allot more to this design then I'll go into right now but it's gives you the idea.
The fairing's and pressure hull would need to be a light material like aluminum and/or carbon fiber and there wouldn't be much buoyancy in the sub which requires allot of weight to submerge, like they have in the Deep Flight submersible. The Deep Flight used small cast aluminum individual pressure hulls for each person, shape close to the body.
