The cracks are symptom of an overload , and the distressed under structure must be repaired , and then made stronger if the cure is to last.
Some of my cracks are symptoms of an unexpected impact (with another boat or a dock) so as long as that is not repeated, a simple crack repair should take care of them.
Others seem to be caused by hardware that was tightened too tightly so again, I suspect a simple crack repair should take care of them.
Unexplained cracks should probably be investigated before being repaired.
