Hey Alan.
Sorry for raising an older thread but I am hoping to complete a somewhat similar build, although my layup schedule is maybe a little too recklessly light.
I'm using a non sacrificial 16' slim prospector with a molded keel as the male plug and hoping to get away with 4oz s-glass, 5.8oz twill carbon, and 4oz s-glass, one yoke, no thwarts, two seats or kneeling thwarts, and inner only gunnels carboned or glassed in as wood or foam. No vacuum bag, no ribs or cores, no floats and maybe no additional stiffening material (maybe a dose of carbon here and there if necessary)--just three hand laid layers in a sole epoxy then follow up fill and finish. The goal is to keep is as light as possible and just barely passable as a canoe, flatwater only. Higher priority is light light weight and determining if I want to build on the experience and jump into a more involved build.
Based on your experience (leaving my 1/2 gunnel idea out of it) do you think the material schedule is maybe passable?--or will it be an expensive wet noodle?
Thanks!
