Coastie - I suspect you'll find the area directly behind the keel once you grind it out similar to what other J/30 owners have found. The laminate on Rhapsody was water saturated, cracked (probably from previous groundings) and had a rotten smelling black goo infiltrated in the glass. When you grind out that area, feather it back and lay up multiple layers of biaxial cloth to build up the strength. Don't just fill it with epoxy because it is an area of the boat subjected to a lot of stress from the keel.

Remember that the boat was constructed with two halves that were glassed together at the keel joint. Make that joint structurally sound if you find it has been compromised anywhere.
