The amidships styling 'hump' is very reminiscent of the "Great Eastern" paddlewheel going back a century and a half. Now, that's retro. http://arnygrimbear.de/GREATEASTERNSTEAM.htm
An old paddlewheel river steamer was my first impression too when I looked at the pics this morning. However, as great as it would be to see someone sign a contract to have this built... I'll put my neck out and say it'll never happen. Unfortunately.
I read somewhere that Lurssen was affiliated with this project. The steep aft tumblehome will require any deckhands to have quite an arm to heave lines!
