I'm almost done stripping fiberglass from the exterior and varnish from the interior of my 1913 Old Town Charles River CS. With the stripping and sanding, I've lost some of the 108 year old wood. I'll need to replace a few planks and ribs, but most of them look pretty good. I'm stressing about whether the lost wood from stripping and sanding will weaken the boat significantly. I don't need to take the canoe down the Allagash, but I also don't want it to be too fragile to use. Any suggestions for a way to test the strength of the wood that seems otherwise healthy?
