I'm trying to figure out the age of my H16 - ser# CCMP8281M81G-A1, etched into both transoms. According to Hobie site the second M is month (January?), and after that the year produced is 8 (1978?) and then model year 1G (huh?), and A1 is a steak sauce. Maybe its an '81? Sail# is 63105, probably original? It seems to match the flamer color scheme, but I don't know. Any insight?
