After cuttin' a hole in the hull do you re-glass?

I have a buddy that just did a ballast install. He cut hole in the bottom of the boat for the water pick-up, my question is; should he have glassed or at least epoxied the edges of the hole (the exposed inner wall of the hull)? Since this is on the bottom of the boat isn't it a perfect place for water to start seeping into the layers of the hull and start delamination? Just curious.

Thanks,
Ryan

As long as he used a good marine sealant between the pickup and the hull he should be fine. Using some around the hole edge between the tube part of the pickup won't hurt either. Just make sure it doesn't get past the part where the pickup meets the hull.

could have, but i wouldn't think it would be necessary.. most thru hull mounts on any boat have no such extra epoxy in the hole.. at least not that i'm aware of.
I would have put some form of silicone sealant around the thru-hull fitting tho.

During the factory tours both at Correct Craft and at Sanger before the rigging process they put glass on the inside surface of any hole they cut. During the Sanger tour Kathy Davidson specifically pointed this out to us. Silicone will deteriorate after time.

If he used a good sealant like 3M 5200 or 4200 or BoatLife caulk he is good. Dont use rtv type silicones.

^ as said, use 3M 5200 to seal holes in the hull, sucks to remove the stuff but it will prevent any water from possibly getting in...

I used 3M 4200 marine sealant on both the inside and outside of my through hull intakes and the seal is solid and will not deteriorate over time due to it being Marine quality sealant from 3M. Bocephus's idea of spreading some fibreglassing compound in the hole is also a great idea.
