Alright Hutchin's obviously did not have computer record keeping back in 1980 (the most likely year of our 16) but after looking through some known boats we determined it to be a 1980. The photo's showed a number of 1270 on the mainsail, which we learned from Salty19 was more than likely the hull number. The Hutchins folks indicated that they DID NOT place such numbers on all of their boat sails, but some were and 1270 kinda matches up with what we do know about her approximate year.
The hull number is a combination of Hutchins ID, ABV
production # 1270
month as a letter (i.e. January=A, Feb=B, etc) ?
month and year as 3 digits (i.e. July 1980=780) ?80 (more than likely an 80 build year)
so here is what we have: ABV1270??80
Hope this helps folks understand the way the HIN's were done and hopefully help ring a bell out there for someone to check their HIN if they have a CP16 from about that year. Still on the trail!
