I found the same thing. I think I asked once about how the trunks are
installed but don't recall if Bob or Jerry ever mentioned it. I assume
they are put in place after the hull is laid up, with the ballast put
into place after the CB trunk is installed. Would be interested to hear
the step by step process that is used.
Anyway, mine was repaired by grinding out the joint, backfilling with
thickened epoxy, faired and a layer of cloth tape with epoxy applied
over that to seal it. The inside of the trunk was then painted with
bottom paint. It's about 3 years into the repair with no problems.
The thickened epoxy fill and tape job could all be done in one step
without the need sand between. It would not be that big of a job.

Hi Robbin,
I had a similar problem when I re-furbed my M15 last winter. Mine
looked like the center board may have broken and dislodged the epoxy
holding the liner to the bottom of the keel. After I dropped the
center board out, I could see that this was not a major problem. The
area ranged from small chipping to about 1/4" in size like yours.
This area was about 18" long on each side of the trunk. I took a
small grinding tool and expanded the area. I used Bondo to fill the
area. After the Bondo set, I faired it and applied bottom paint. The
fix is now 14 months and looks as good as new.
