For Sure!!! Many Nautalines, Chris Crafts etc. have stringers so far gone that the hulls are malformed with a big hump in the cabin floor. It's almost impossible to push the bottom of the boat down into position in the water.

Note: when you get all the bad wood in a Nautaline replaced you have a hell of a good boat because the thickness of the fiberglass is more generous than on most other brands.

Replacing bad wood is an expensive process to have done due to the fact it's labor intensive. If you can do it yourself you can come out pretty reasonable. (if you can stand the fumes and itching)
