There were several producers of Peterson 33s over the years. Chaser yachts built a 29 and a 33 in Ontario for a while, these molds were later bought by Bayliner and produced as US yachts(Buccaneer 295/US30 & US33) for a time, also in various versions.
There were also a series of 33 petersons built in Korea, local scuttlebut has it that these were quite well put together.
You're looking at typical late 70s/early 80s IOR design, pinched ends, good upwind performance and possibly a bit rolly downwind in a breeze with the kite up. Short "E" measurements and relatively long "J" maximimizes headsail and
spinnaker sizes for the
rig.
The cockpit will be smallish, especially compared to newer boats with maximum beam extended aft.
I met a fellow this past summer with a Korean built 33, he was happy with the boat with the exception of the galley and the size of the head - he was a tall man and found the head very tight, the galley had little space or storage. However he said he did a lot of singlehanding.
Hope this helps.
