After a week of working evenings my hull is back ready to go sailing.
All the sanding is done and the hull-plates are screwed down again. I edged the hull-plates with thickened epoxy to take some of the shear-load off the screws. I'd done this before and it seemed to work well in the de-planking, as the plates were able to pull away from the hull (relatively) cleanly during the crash.
While I was working on the hull I augmented the bow-spring with a tennis ball and glued the tiller-head to the tiller-post.
