I don't know that I agree with that...not on this boat at least. I say that as I do have one area of actual structural failure...aft area of fly bridge where previous owner didn't properly seal a dinghy tie down fixture, rain got in and rotted the core. You can step on that area and it sinks as if there is no core....and yet ironically there are no cracks there whatsoever.
The areas there are cracks check out fine with hammer taps and moisture meter.
