The notion of the stringers creating a shear line is poo poo. If they were bonded to a large flat section of a hull with little or no side support then yes you will have a problem. Where the stringers are placed in these boats, and the shape of the bottoms there is virtually no chance of this happening and if it did you were in WAY over your head. The purpose of a stringer is to provide a direct stiffness to the hull. Placing it on top of the core can comprimise integrity due to it being on top of two laminates and a not so solid medium in between.
Later models with the wider floor had the glass stringer over the core pad and on most of these boats I've worked on it came up with the floor pieces and the laminate over the top of the damaged core, or if in the case the floor was seriously rotted I was able to grab the stringer and pull it up by hand in one piece very easily.
At any rate 90% of these boats were built like sh*t and were falling apart before they made it to the trailer leaving the plant. So if your half way competent and put a little time and effort into your job any way you do it, the boat will be better than when it was brand new.
