Default I cut too deep, now what?

Pretty much I was cutting the floor out on my dusky and it appears I cut too deep. For about 3 inches I cut all the way thru but for the other 30-40 inches I probably cut half way thru the shell of the boat. What’s the best way to repair this, fill it with resin or glass it?

It's not a big deal. You're obviously doing some serious work, and will be doing fiberglass and gelcoat work in the future.
I would tape over the hole on the outside of the hull and repair from the inside. Paint a little gelcoat in the cut, then resin and glass fibers packed into the cut. Then a couple layers of cloth over the repair.

How about some Six10 epoxy. It is a structural and gap filling epoxy.

What he said ^ Also might have to bite the bullet and grind and glass that cut on the outer side of the hull for it to be perfect.

Not the end of the world.

Grind down from inside and build back up with new glass. Flap disk on grinder and taper the area a bit to make almost like a “well”. Smaller pieces building up to larger

Agree with the others who say to grind down on both sides and glass it.

Would love to see some pics of what you are actually doing. I have a Dusky 233 that someday I will have to do some fiberglass work on too.

That was my original thought, but I don't mind going above and beyond to prevent and issues.

........Cut once

I felt like an idiot when I saw the sunlight thru the hole. I was trying to cut the inside liner of the boat and had to rely on feeling the cut off wheel giving me to try and differentiate the inside liner vs the outside. The first side I didn't come close but for some reason the remaining side was more difficult.

For sure.....Ill start a thread tomorrow. Basically I am removing all the wood, selling all of the components and building a new boat from the bottom up. There is something I like about Dusky's but I can't deal with rotting fuel tanks, wood stringers and transoms that seems common in many of the older hulls. I have decided to redo transom and stringers with coosa board, an armstrong bracket, and potentially Suzuki twins on the back.

Transoms and threw hull fittings are put together with 5200. Why not
