Royalex Canoe

I have an Old Town Camper canoe. A wooden retaining wall fell on top of this fall and one of wood with large nails pierced a hole in the hull below the waterline. Looking for suggestions on how to solve this problem.

BONDO is a resin repair of fiberglass, you can buy at Lowe's or Home Depot. Just do not get any of it on your hairy parts ... I speak from experience here.
