After cleaning up the underside of the rub-rails, I feathered some of the glass on the lower side panels. This is the glass of the upper sides that continues for a few inches over the joints of the side panels (underneath the rails). I filled the gaps between the side panels and the bottom panels with thickened epoxy. These gaps are there because the panels meet at an angle with their inboard edges (once wired) together.
The joints where the bottom panels (and the keelson) meet are roughly sanded and filled with epoxy. Much of the epoxy will be removed again when things get rounded over and faired. The rear of the keel needed a thin shim (plywood) to make things flush with the transom – an exercise in ‘making it look pretty’.
