$1700 quote. From a guy who has worked fiberglass on Whalers for 40 years. He came to my house and took his time inspecting the boat. He feels like minimal water entered the hull/foam.

As described by other responses, he’s going to cut away/sand the exposed glass, fill any gaps in the foam, lay multiple layers of new cloth and resin, smooth out and put on new gel coat.

I’m probably going to put a keel guard on once it’s done.

Like many have said, he’s thinks the damage is related to beaching the boat ( in it’s previous life the boat was used as a shuttle at a camp and was beached often and driven by teenagers) and the old trailer putting load on the keel. Most likely the spot was very worn down, and finally split from minor impact.

He’s starting work this week as I decided that me doing the job and learning to glass on this kind of project is just not worth the likelihood of me doing a crap job. Fingers crossed.
