Yes of course C&C made several versions of their 26' -the original 26' -4" - then came the 26' Encounter and then the 26' Wave.- but unless they custom build for the same model years the lengths, draft etc to individual orders -- (which I doubt) --- the posted specs seem to differ --
For the record I posted the specs for the early C&C 26 as shown in it's factory for 1977 owners manual.
