Re: Decommissioning through hulls?
The term Best Practices comes into play
BEST - Hull ground outside and inside, glass replaced on both sides
GOOD - Hull ground on inside, glass replaced
MARGINAL - Epoxy in hole.
Since the epoxy is a different density and flexibility than the surrounding glass, the edges will be under greater stress and will want to shear or tear. Will it happen? I don't know. This method would probably work fine, but I'd stay with time proven methods if you go far offshore. Pick up a book by Don Casey. Easy read, step-by-step. Even a Geico advertising icon could do it.
