Another good few hours today sanding and more sanding  working down the grades of sandpaper but I can finally see the the finish line. Next step is to clean hull and gaps between planks with white spirit and then applying a coating of wood preservative.

Following some inspection from people more learned than I the plan then most likely involves completing some minor repairs and replacing flexible sealant in readiness for move to “finishing shed” for painting and varnishing. It’s been a slog but feels like I am at last approaching the home straight!
