Restorations all take the same path. De-rig the boat, build a cradle, uncap the hull, cut out the bad, replace with good. Re-rig

make sure the pulleys are all in-line (use a straight edge or use a laser pointer) get a new belt tensioner.

Tapping doesn't reveal anything. For it to sound hollow, takes decades after the rot starts. Take a test drill and check the shavings. FLIR camera will help. Also, weigh the boat and compare to spec.
