Is it possible to determine the year our Sunfish was built based on the hull number?
FYI CMAC233's explanation applies starting in 1972 (I think) when the hull number was stamped on the top right side of the transom. Prior to that, it was just a serial number on the plate glued to the hull behind the splashguard. If you are interested, this thread gives probably more detail than you care to know about the subject Sunfish Age and Hull IdentificationWow - thank you! We were able to determine that it was pre/1971 but couldn’t zero in any further.
