About this 3D model

My first speed bootwas 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 http://youtu.be/WKB13EdQD4Yhttp://youtu.be/e6QYdzF0Z5E
