I don't know of all the boats and thier set-ups and I wasn't going radical with the word "turbo'd". I just meant if there were minor changes outside class rules that would make an appreciable difference to performance. Examples might be a different rudder or balanced one, changed keel not following templates, code 6 or 7 mains, or masthead spinnakers. None of this might be out there so it might not be something to worry about. We aren't worried about sail materials, weights, changed stoves, etc.
