Bill: from information shared by Randy G. - In 1988 (roughly at hull #400) the centerboard was changed from 220 lbs cast iron to the same centerboard as is used in the M15, weighing 40 lbs. The M15 is comprised of a fiberglass-lead-fiberglass sandwich and does not require a winch to raise and lower. Also, the ballast was increased to compensate for the change in centerboard weight, and the ballast was changed from steel punching to lead. These changes took places over several boats. For example; our [Randy's] 1988 M17 #410 has the fiberglass centerboard but steel punching ballast. (can't remember where i got this specifically ... what i have is credited to Randy.) :: Dave Scobie --- On Wed, 3/27/13, Bill Wickett <billwick@gmail.com> wrote:
Who can advise the year that the CB was changed from iron to laminate? Which CB would an '89 M17 be likely to have? Would the ballast be iron or lead?
Thanks,
