I am actually working on something similar, a ground-effect aircraft. I doubt it will perform very well on the first few flights but i think I can improve it as I experiment with it more. I'm looking for amphibious capability and it will probably have enough power to climb temporarily out of ground effect like the hydroplanes in the vid that was posted.
Mine will look similar to the Russian ekranoplans that were built in the Cold War, aka the Caspian Sea Monster. It will have short, stubby rectangular wings toward the nose and a high t-tail with the motor mounted on the vertical stabilizer.
Right now I'm finishing up the CAD drawings and I will start a build thread with plans when I have the prototype built and tested. Good luck with your design, i have to say that is way more likely to work than my crazy contraption
Pic is what my ekranoplan will look sort of look like.
