Looks great! I'm doing the same thing witha 14' aluminum v-hull but I'm not ready to release pictures yet!! :) I'm taking pictures as I go.
How stable is it when you're standing on the casting deck? What size motor do you have? I'm looking around for a used 15HP for mine.
I've figured that my planned mods only add 150 lbs total to the boat, that's for a front casting deck and a floor in rest of the boat.
