Does anybody have a resource for finding the exact build dates based on the hull number? I understand that Pearson when to a HIN system around 1974 and that is fairly straight forward, but my boat a Pearson 33 with a hull number of 175 is a bit more difficult to nail down. The previous owner had it registered as a 1971 build. I see others for sale with hull numbers very close to mine but different build years (one is listed as a 1974). Just curious if there are any surviving records form the company?
