Jetpack thank you for your informations.
I saw your work in the front of the topic and all I can say is: respect!
18" long is the boat in my avatar.
It has got 700grams (1.543 pounds) but it is fast as hell (electric)...
I hardly belive that Cox can push the same boat to the reasonable speed.
I will use lighter materials on this vintage build!
I got all the needed information that I asked for.
When the project hits the working desk, you guys will be first to know
