Hank Hinckley spun off from the family to build boats of high quality at a lower price then a true Hinckley. If I recall I believe around a dozen or so boats were delivered from 39-52'.
I looked at a OC40 while searching for our current boat, and while the workmanship was good, I felt the asking price at that time was too inflated. We also found the interior, like the B-40 to be too small without a quarterberth.
