I certainly don't know everything there is to know about sailboats, or even our own boat, actually. What with all the cross-breeding that's taken place in the sailboat industry over the years, perhaps I've got this wrong, but TTBOMK Pearson and Cal are, or were, two different sailboat manufacturers. Pearson is out of business. Don't know about Cal.
There is a "Cal 2-46." Pearson does not appear to have made such a boat.
Your question probably would have been better-posted in the "Buying a boat" sub-forum.
