My first speed boot http://www.thingiverse.com/thing:312235
was enlarged bit by bit of three different parts. This time it should be a hull as if made from one piece with no need of spay rails. Additional it has a deck now to protect electronics. If you seal it with elastic tape and use a compensator grommet for the rudder steering rod it can be unsinkable, but I hope there is no need ;-)
The overall length is 414mm.
The camera mount is provided for this case for mini cam

And yes, this time we didn't need the helping hand of this beautiful mermaid, because I decided to design a flexible coupling instead of the heat shrink tubes.
Update:
I uploaded smaller hull parts with hight 149mm.
The shortest possible hight I could make is 127mm.
Update 7.July 2015:
I uploaded smaller deck parts with hight 116mm and 117mm
