Not an easy fix, especially if you have both sides to repair. Reefmagnet's solution might be made to work for you. If you use timber for the pads, after you've drilled the pilot holes for the screws, soak the whole pad in a bath of penetrating epoxy, and let it cure. After it's cured, bond the pads to the sides. Paint
to match hull
color. Install dodger, and hope for the best. Otherwise, you're going to have to open it up from below, and install backing plates
; and that may really have unanticipated consequences, might want a response in writing from Beneteau
on that one.
You'll want to shorten the frame by the height of the pad so that everything will still fit.
