In the process of prepping our 22 ZX for the season I came across something rather unsettling while waxing the hull. It appears that a number of nasty looking stress cracks have formed on the aft end of both of the inner strakes. There are also a number of fine spider cracks running parallel to the stringers and some parallel to the aft bulkhead:

It appears that the previous owner had this happen and had it fixed at some point (which they neglected to mention). I'm wondering what could possibly be causing these to form and what I can do to fix them? I plan on grinding them out, filling with West epoxy, and then topcoating with some gel but I know unless I find the root cause these will likley return. Any information is greatly appreciated.
