Today was spent planing back the ply doubler on the backbone to reestablish the “V” shape on the bottom.
Even with the aid of the Makita power planer it was still a lengthy job and much hand planing was needed for the final adjustment.

Power and hand planers make a lot of wood chips reestablishing the “V” on the bottom of our Didi 40 CR
I managed to finish from the keel to the transom including belt sanding the doubler to make sure it was flush with the ply bottom. Tomorrow weather permitting I will try to finish section from the keel to the stem.
