H25 HIN codes

Okay; I did search the archives and do not have an answer to this question, so I'm reopening this bag of worms. Can we H25 owners compare HINs?

My boat has a number format which I believe to be unique. I have deciphered most of it: HUN25027M74H-G.

Here's what I know. At the time this boat was built, Hunter ran five production lines at Marlboro, NJ, two of which were Hunter 25s. By the 1974 model year, one line was of the trunk-cabin model and one was of the 'blister-canopy'/'flush-deck' model. Currently, right next to my boat sits one of her March 1974 sisters, a trunk-cabin model. This boat's number is HUN25140M74H. Though Hunter did make a whopping 500 H25 hulls per year, they did not make 113 in one month-- so clearly the '027' and '140' are not sequential numbers in the same series. I have concluded these represent the two model lines-- '0' being the original, 'flush-deck' model and '1' being the trunk-cabin model. So my boat was #27 of the flush-deckers and the boat beside her is #40 of the trunk-cabin models, in the same production series.

What defined that production series is anyone's guess (especially, sadly, now that Warren Luhrs is gone). At first I thought my boat was H25 #27; but that would make no sense given the impressive production schedule. H25 #27 probably occurred sometime in November 1972. The series was probably (but not guaranteed to have been) the month, in this case 'H' (March). The 'M' indicates that the HINs follow the model-year format (based on that of carmakers, which Don Launer fails to surmise in his otherwise good article in Good Old Boat).

My question, for all you Cherubini Hunter owners out there, is this: does anyone else have two letters, hyphenated, at the end of the HIN code? So far I have not seen this on any other boat. My boat had no special factory features and was not modified from some other model. My first suspicion was that it was in the 'glass shop between 28 February and 1 March and that someone, knowing this, attributed a hyphenated HIN to the boat built at the cusp of the month. (Typically this number is-- still-- applied by makers in via a Dyno label-gun tape, stuck into the mold backwards with hot glue before the gelcoat is sprayed.) It could have been an error by the factory as well, as several other odd HIN formats may suggest.

If anyone has a definitive solution to nonstandard, especially hyphenated, HIN codes I'll be glad to hear of it!

Thanks.

BTW-- because of this belief, I celebrate Diana's birthday on 29 February. She just turned 40. We're planning a quiet evening in, this week.

Off topic-mines a 76 30 so I won't be much help with the HN ciphering on older 25s, but was wondering if you have a current link (and maybe updated experiences) to your instructions/material suggestions for strengthening weak decks with the drilling, drying and epoxy injecting you've described here before. I am considering attempting this spring- hope you and Diana enjoyed her birthday

J -- if you check out my boat blog there's an article (adapted from one I posted here) about that subject. Let's keep this about HINs! :)

My 36' has no hyphons on the end, just HUN36065M80J, which I guess makes it Hull 65?

My hull number

John, My hull number is different style than yours. I have a 1974 Hunter 25 with a wedge (flush) style deck. My hull number is HUN25045M745, which the state changed to HUN25045M74C.
I've previously exchange emails with you as suds however I'm no longer able to log-in with that user ID

Interesting, John.. I am not an expert on this but I did follow the 25's avidly as they were being produced. I don't think that Hunter built the blister top once the trunk top was introduced. I remember how disappointed I was that the blister top was discontinued because of how great it looks.
I remember reading on this forum sometime back that the hyphen was a designator for a boat started in one month and finished in another, just as you've surmised. The practice was not limited to Hunters. Remember that this HIN stuff was brand new at the time and they were transitioning from their own number system to the "new" gov. mandated one.. Again, my recollection and not necessarily fact!

Kloudie--

They did make them both, most likely side-by-side at Marlboro. Both 1974 truck-cabin models and 1977 blister-cabin models exist; they were not built alternatively but concurrently.

You're right about the learning curve about HINs by builders. At Cherubini ours were all over the place-- but the 'errors' (if we call them that) are easier to decipher and I can read any C44's HIN like some read Morse code.

Suds--

Apparently your boat was built in October 1973. Hunter used the M-designation, meaning they dated their boats in the way auto makers do, with August being the 'A' month for the following calendar year. 'C' is the third month when August was 'A'.

I still don't have an explanation for the 'H-G' code in mine.
