I never trusted the stringers on the old boat a Sunkyung Marine 37' sedan. After about 12 years of ownership I cut out the old stringers and fabricated new. The old were glass over plywood forms. The glass was good but tapping on them indicated the wood was gone.

Removed the generator and fuel tanks. One of the tanks needed repair which I covered here a while ago. With the way clear I laid the sawsall on it's side and cut out the stringers and tank supports. Then ground everything clean. As I lifted out the old supports the rotted wood fell out.

I made new out of plywood saturating each layer before it was screwed and glued together. The stringers were bonded in place then glassed. The solid wood is way overkill but I made then the same thickness as the original hollow units. I am sure I could have made them half the thickness and still have been plenty strong.
