The Nacra 17 is a regional class. IF CRAM does not turn in their comparative data against the other starts... the rating will never adjust. (I have no idea whether they do or don't)

The Nacra 5.5 uni had the same history. The boat started out slower then a hobie 17 (74.0) and raced for several years at 74.5 It was very popular in CRAM as a one design and they did not turn in data.

Eventually they did turn in data and the number dropped to 69.5 or so.
