I am not an engineer, but I know one. Look at the tabbing of the four stringer layout. Almost connecting the layup. Spruce has a nice tight straight grain and of course adds beef. Plywood adds even more. Off the factory floor, I would say these are much stronger. Once the wood rots you see fracturing typical of these pictures. Please remember these hulls are older than most of the lurkers.

The old foam adds little structure and has fewer tabbing overlaps. You don`t see as many fractures but water intrusion can cause this and other obvious issues. My Slacker has mint stringers, but she shudders a good bit if I push her.The only time I pushed her really hard was trying to run with Bones at Peanut. She still sneers at me.

If I were going to do one from scratch, I would do a composite grid with big weep channels.
With epoxy. There I said it.

Checkout Caymanboy`s recent build for hullside coring.
