I would go to a boat shop and ask them. Those people know if it's worth fixing or not. I have done honeycomb-fiberglas repairs and it is a lot of work. You must rout the damaged, layup new cloth, sand, and keep layering and sanding for hours. I repaired a P# Orion Radome that had a Gooneybird stuck in it, not the DC3 but an Albatross with a 12 ft wingspan. Took 3 weeks, due to the cure times and 6 coats of paint.
