37C HIN's
Here’s what I found out at http://www.boatsafe.com/nauticalknowhow/hin.html. From November 1, 1972 to before August 1, 1984My HIN for example: HUN37377M84IHUN = Manufacturer (Hunter)37377 = Hull Serial Number (I learned somewhere that, for Hunter, the first 2 digits represent the length of the boat)M = “Modified” (Don’t remember where I got that)84I = The above link says this is the date of certification. 84 is the year and the letter “I” is the month code. Being retired Boeing and knowing how airplanes are certified, I think this date could be anywhere between the date of ordering and the date of delivery.Month codes: (By fiscal year?)Jan FFeb GMar HApr IMay JJun KJul LAug ASep BOct CNov DDec EAfter August 1, 1984:Mike Harris’ HIN for example: HUN37401H485HUN = Manufacturer (Hunter)37401 = Hull Serial NumberH4 = Date of certification OR Manufacturer.
