Enthusiastic about Wooden Canoes
You are on the right track. Just clamp on some braces.
You will likely need to remove the planking along the keelson to access the crews that hold the keelson to the ribs.
I would pull the keelson, clean out the gunk, repair it or replace it, and reinstall it before doing ribs.
perfect, thanks Dave. good to get back to work on this!!
