1982 Bertram 46 HIN

Okay. The original HIN is apparently a casualty of the hull extension. There's not an old USCG official number anywhere in the bilge. And there's nothing in any log book, registration papers or other records aboard the boat.

The boat left the Bertram factory over 30 years ago, since then it's had a major modification and it now lives half way around the world. So, what is the HIN going to do for you?

Well, you already have that;

Unless you need the pencil impression or a picture of the hin, you have what you need, hull 30, year 82.
It's not like a vin for your car that includes the color code, trim package, engine and rear ratio.
The "B" may mean something, M either for marine or molded.
BERR is the mfg i d code. 00 is the first two digits that make the 4 digit hull number. Yours id 30 or 0030.
your hin IS BERR0030M82B. Mine is just like that, any old Bert owner out there can tell you his is near that also.
Oh, the dash and 3 more numbers were hull length & beam, witch has changed anyway and not on every hin I have seen on vintage rear ends (there was that red-head,,,,).
