Hull identification number
« on: June 08, 2015, 07:43:34 AM »
"Boats that were manufactured from 1970 - 1973 carried a seven digit number. The fourth
       number from left indicates the year of manufacture. "
 In 1973, Glastron starting using letters (GLA...) in the Hull Numbers.

Prior to that, the  early 70's were just seven numbers, with the fourth number from the left being the year
 (4322414 would be 1972). Starting in 1973 we were required to use prefixes.
       Using the prefix you can determine the location the boat was built. Then
       the seven digit  id number will follow. A single letter and 2 or 3 more numbers which will tell
       you the year of manufacture. These procedures are in accordance with coast guard federal
       regulations"

Note that from 1973 forward hull ID numbers were stamped into the rear of the boat. This was federally
required for all '73 and later boats. This is good because the number will always be there and easily read in most cases.

The HIN (Hull identification number) was a federal requirement beginning in Nov 1972, for 1973 model boats. It starts with a 3 letter Manufacturer identification code, followed by a 5 digit serial number and ending with the date of manufacture. The reason for this requirement was for safety and defect recalls. The law allowed for two methods of display. The one Glastron chose was to list the model year M and then a letter for the month of manufacture. August was the traditional first month of building new model year boats so A= August, B=Sept, etc.

So the HIN for your '78 CVX-18 is serial number 10480, Model year 78, built in the 8th month, March 1978.

The standard changed again in Aug 1984. 3 letter MIC, 5 digit S/N, single letter for maunufacture month where A=Jan, single number for manufacture year, two number model year.

Under the 1984 HIN rule your 1978 CVX would have read GCV 10480 C8 78

The "M" means that Glastron was using the optional display of model year instead of certificate date. "M" stands for model year.
When this law went into effect manufacturers didn't like that they would have to stamp 72 into a 1973 model hull so the law allowed the optional method that Glastron used of stamping the model year and then a month code.

After 1984 Glastron HIN codes:

Found these numbers on the Glastron History page. Guess they made a lot more boats than I thought!

CNO HIN Decoder

Our HULL ID Decoder breaks down the Hull identification number into the following information:
The HIN or CIN you have entered meets the Current-Format HIN format. It might also be a type that contains the country code and thus the boat comes from USA or Other . The serial number of the HIN is 06174 and is set by the boat builder. This boat or vessel has a Certification Date of (6) and a Model Year of 1987 with month of build (July) based on the formatting of your hull_identification_number (HIN) .

The manufacturer identification code (MIC) of your craft identification number (CIN or HIN) is CNO. This MIC (CNO) stands for the company name Glastron-conroy Indust which is currently Out of Business. This boat manufacturer has other company names (CNO sometimes goes by these name(s) Conroy Industries, , , or .

This company (Glastron-conroy Indust) is owned by David Mosley and is located at 3150 I-H 35 W in NEW BRAUNFELS state of TX. It manufactured this vessel and placed your HIN or CIN on the hull. The Parent Company for this boat maker is GENMAR HOLDINGS INC ().

Make sure to compare the date of boat manufacturing with the dates in which the company was actually in business.
