After watching an American guy launch and navigate around a local waterway in this kind of boat (please see video clip below) I thought I'd try making one too.

As its only 8' 6" long and 3' wide and 2' deep, I'm wondering how much Resin and Fibreglass mat I'm going to need to cover it. 2 layers should be ample as I'm only poodling around Lincoln's Brayford pool and Foss dyke Canal in it.

Any advice would be gratefully accepted.
