For performance information go to www.phrfne.org and compare the boats that suit you. The smaller the number the faster the boat with the exception that these numbers assume that a spinaker will be flown. Add about 21 to these numbers for no
spinnaker. This only matters if you compare to say a Nonsuch 26 that files no spinaker.
The Cal 34-1 has a rating of 174 which is moderate in performance.
As to value I have no idea what the market is like where you are. While the Cal 34 is big enough the boat does not stand out to me that one that would be my first choice in this price range.
A friend just sold a C&C 35-1 for $26,900 with the A-4. In 1995 I bought a C&C 35-1 for $22,000 on the east coast and it had a diesel but I admit nothing else but old racing gear. These are 1973 boats.
If there is a C&C 35-1 or C&C 35-2 in your area then go and look at it. There are other boats too for sure but these were really good sailors in their day. These boats have nice
lines.
