Based on your HIN,
or Hull Identication Number,
Your boat was manufactured by the Stowe Canoe Company of Vermont in 1980.
If you look closely, the last digit is probably an I rather than a 1.
The USCG has an on-line database of MIC's (first 3 characters of the HIN) that indicate the manufacturer, and the last three digits are the year and month that the boat was built.
