HIN Format, XDYDxxxxMyym or XDYDxxxxmmyy or XDYxxxxxMyym-D
XDY = O'Day D = Day Sailer (no distinction between DS I, DS II, DS III) xxxx or xxxxx = class# M = model year format m = letter code for month (A = August, B = Sept., C = Oct.......L = July) yy = model year. mm = month if "M" model year was not used, O'Day as well as other builders used both numbering systems, but not at same time.
Using my boat's HIN, XDY10201M79E-D, XDY=O'Day, 10201=class#, M79=1979 model year, E=December 1978, D=Day Sailer. The modle year under this format ran from August to July, so 1979 model year was August 1978 to July 1979.
On boats built before the HIN requirement went into effect on 01 Nov. 1972, O'Day gave every boat 2 numbers, a Hull # and a Class#. Hull # was based on O'Day's total number of boats built, Class # was based on how many of that class had been built. My old (1969 or 68) Widgeon was Hull# 22698 Class#1791. This means that she was the 22,698th boat built by O'Day and the 1791st Widgeon.
