Minnesota II dimensions - old vs new?

Hi All,
Can anyone comment on the “history” of the Minn II especially regarding its dimensions and keel line/hull shape. we got a minn II in tufweave years ago and i was looking at getting another in kevlar UL. It seems the current model is deeper in the center and looking at old wenonah catalogs it is listed as an inch deeper. have any of the other parameters changes and has anyone noticed any difference in performance of the “old vs current” boats?
