Let me confess that since the first time you posted on the IY 13.98 it has become my new "fantasy" boat for 2-handed extended cruising. There is simply nothing about it that I don't like, save perhaps the wood decks, which I'd dispense with if that was an option.
Thanks for the clarification, for I did, indeed, mean carrying max beam further aft in the newer designs, not simply having big, fat beamy boats.
While it's difficult to argue with J Boats success in IRC / ORC with their recent designs, I'm wondering what has determined their choice to not take an even more contemporary approach. If you look at their newest designs - the J70, the forthcoming J88, and the J111, they all look very much like J Boats, with max beam right about or slightly aft of amidships:
Perhaps I should drive up to their offices and ask them.
