Dennis,
I seem to remember from the discussion in the Marblehead/Halifax thread its 105ish for a J30. I think the main problem is best illustrated when the lower limit is removed takes WingsNuts to 74.4 when many other boats stayed the same. See below:
Figure B-4 illustrates the value of the Capsize Increment without the lower limit. There are a
number of boats effected but Wingnuts has a value that is notably different from the rest of the
fleet. If the full negative value of this design trait was applied to the equation, the Kiwi 35's
stability index would have dropped from 100.7 to 74.4. (Figure B-5). None of the other boats in
the Chicago Mac Fleet would have seen such a drastic reduction if the full increment correction
was applied to their stability index
