J24s have been raced for over 25 years now, even offshore. But the
sinkings seem to be a recent phenomenon. I wonder if people are just
pushing them harder, as if they're dinghies or sportboats, where capsizing
is a normal part of sailing.

That's certainly one possibility but there is also a chance that the
deck cores are absorbing more moisture which would decrease stability
to a certain extent. Are the capsizing boats competetive or not? If
yes, I'd guess that it is just more agressive technique.
