Hmmm...that sounds odd BillyBob. Unless you hit something the only thing I can thing of is that there was a stress crack below the waterline and when the water got in it underway it peeled back the laminate.

If I were you, I would get that baby in a heated garage or barn, turn up the heat and turn on a dehumidifier and let that her dry out for 3 weeks or so. Then I would do a complete inspection of the hull. after that start grinding back (12:1 ratio)the damaged laminate, clean with acetone and then layup with glass. This is a good situation to vaccum bag in my opinion.
