Two Hulled Impeller Boat RC (experimental)

I wanted to use the full thrust of my impeller. As seen in the video of the impeller boat: http://www.thingiverse.com/thing:274054
the high positioned and heavy motor capsized it already with little throttle.
So I took two long boats and put them together to get something like a two hulled boat. The one is allready puplished: http://www.thingiverse.com/thing:284692
The second one is the enlarged impeller boat.
Both needs a bridge to mount the impeller housing which connects the boats.
