More modern boats such as the Farr 1020 (for example) are selling for what the half tonners were not all that long ago:

A design such as the Farr 1020 isn't compromised as are IOR boats with their big bulges amidships and crazy pinched sterns to fit in with the handicap rules of the day. IOR boats don't perform downwind. A Farr 1020 will plane and surf downwind, leaving the old IOR boat in its wake, and with a nice fractional rig
That is certainly a lovely yacht as it should be for $50k. Some of the IOR yachts were taken to extremes so as to be rule beaters. I don't think Peterson went that way. I had a Peterson 2 tonner, 42' and she tracked beautifully off the wind.
If you look at most of the Petersons you will see that they are characteristically "full" in their hull shape, bolted on rather than moulded in keels and therefore not wine glass shaped with little or no tumblehome and they would win races.
Peterson was a natural ansd started putting yachts down on paper at the age of 10.
Compare the Peterson to the hollowed out bows and sterns of the other yachts.
