Hi Shane, having made my own fibre glass hulls the most important points have been well covered in the Forum, just a couple of tips, Don't use a silicon based release agent as you will have trouble with any paint finish you may apply,it takes some shifting.
I have used perforated zinc for planking the plug mould if the curves are complex, it takes the shape of the curves easily, then I filled the holes with polyfilla and sanded down.
