When I had my boat in New Zealand
, a large trailer backed into the hull punching a hole in the hull below the waterline. The catamaran
was supposed to go in the water
that day, and so I didn't particularly appreciate the hole in my hull below the waterline.
Repairing it was easy. I chamfered the edges of the hole and did a fiberglass
repair the same day. It was a piece of cake.
In your particular case, I would take a piece of foam core and immerse it in West Epoxy
, and then slide it into the hole. Next I would chamfer the edges on the inside and outside of the hull and lay in about five layers of fiberglass
circles of increasing diameter to fill in the hole on the inside and outside of the hull. Then I would sand and paint
. The whole job could be done easily with a few hours of work.
I wouldn't use filler as it is brittle. Bog shouldn't be used for structural repairs
