Some taper the core out about at the LWL others go lower , core ALL the way to the keel is uncommon...
FF: I don't know what to say but Krogen 42's were built with the core to the keel from 1979 to 1993. From 1994 to 1998, which was the end of production, the core stopped at the water line. We had a Slocum 43 designed Stan Huntingford that was also cored to the keel.
