The 3 Cal 39s we had at the club were Hunt designed. Hunt and Co. were practically in-house NAs with O'day for most of their career and ours were built in O'day plant in MA. They were literally the last 3 built as O'day was going out of business at the time. The sail club owner bought those 3 at a liquidation/bankrupcy
auction at the last stages of the build, he just had to finish up rig and may be
steering and such. I
recall he was gloating that in the late 80s he paid for them about $20K each, almost finished.
In the 5 seasons which I sailed them we were in 2 or 3 decent storms as we always had a tight schedule, etc. Several were bad enough for the hangers on (gfs, non sailing buddies, etc) to bail out at the first opportunity and me and my sailing buddy had to deliver the boat back to the club by ourselves for the last 80-100 miles. I actually liked that experience and gained a measure of respect for these Cal/O'day boats. When they would slam off of a wave we were not worried as she felt solid and robust.
Don't have any experience or thoughts about their
maintenance, etc as being club members we were not concerned with it. But I do
recall that one of the three was constantly not available due to this or that issue. Not sure if it was something structural or just that boat's bad luck to be out of commission so often. That was our major point of contention with the club owner - that he advertised and collected memberships to 39 footers based on 3 of them in the fleet but realistically there were only which made for some scheduling issues to be sure. Some club members didn't even realize that there were three 39s.
Also I remember how we once had an
engine issue, it was stuck in hi revs due to some linkage breakage, and were able to remedy it by jury
rigging some piece or other. The
engine access was pretty good from the aft
cabin. It was PITA of course if you had to sleep there while motoring.
