Not a great photo, but taken on a phone through a waterproof cover from a dinghy, so not too bad under the circumstances. I squirted epoxy under a large loose flake and stuck map pins into it to hold it shut whilst the glue cured. I cut off loose plywood edges with the razor sharp Leatherman knife I got for my birthday and then coveted all the edges and scratches with more epoxy. It all felt rock hard when I pulled the pins out an hour later. Always pays to have some Rapid araldite on board!
