I don't believe that a "dry" boat exists. Between water ingress and condensation most, if not all, boats will have areas where water collects. The solutions are ventilation and limber (drain) holes. TIH has a few small areas of rot on shelves and wooden partitions. So far the water source has been traced to the existing chain plate installation.
Fortunately solutions are simple and relatively cheap. Git Rot Penetrating Epoxy works well on rotten wood.
