Ok, I get it. Those designs are growing on me... like a fungus.
Only thing I dont like is how two dimensionsal you are making them. You have the top down look perfect, but from a perspective, dont you think the middle part could use a little 3D elevation? If thats where the bridge is, I'd expect, and like the look of it would it be built higher than the pontoons. Ya know? Whats ur take?
